I'm like you, OP. I also am philosophically opposed to spending more on audio than on screen. That being said, good speakers do last for a very long time: if new formats ever come out, you can always upgrade the receiver and you can keep your speakers forever.

I did a lot of searching and I ended up with a good compromise that allowed me to have a LG OLED 65 together with a set of solid speakers.

​

Here's what you need to know:

​

- The latest OLED TVs are pretty much the same as last year's. LG B7, C7, B8 or C8 are all the same TV pretty much. Get the cheapest you can find. I bought mine on greentoe.com. I offered 1900$ for a 65' B7 this past April and my offer got accepted. You can even try to price match it with your credit card, I think (search in this sub). This may save you a few dollars more. Bottom line is: you should be able to snatch a 65 OLED for ~1500-1900.

- You can order a refurbished sub for a fraction of the price. I have the Denon X1400H that u/robotdinofight recommended, and I also bought it from accessories4less.

- Atmos speakers are mostly marketing BS. There isn't much sound that comes from above you in movies. That Denon is compatible anyway, so you can always add them later. Before you do that, just go watch a movie in Atmos at a theater.

- Sorround speakers are not that important either. Your dialogue is coming from the center speaker, and music etc will be on the front channels, with just some in your sorrounds more for ambiance than anything else. You can go with *very cheap* speakers here. Source: Zeos's guide here. I ended up buying the cheapest speakers Zeos recommended: Micca Covo-s for 40$ the pair (a factor in my decision was also that I had the speaker stands I was using for the cheap Logitech 5.1 PC system I had. Speaker stands are expensive too so factor in that cost too). These speakers are honestly not great: I tried using a pair of ELAC B6 and yes, sorround was much better. But I like HDR and perfect blacks way more than better sorround, so I ended up returning the ELACs and kept the Miccas as my rear. Maybe I'll upgrade some other time.

- If you are like me and have neighbors and a wife who's not into loud explosion, you really don't need a crazy sub. I have the Elac S10 and that's *more* than enough for us, my wife wants me to keep it down. Get a cheap one! Mine was only about 100$. See Zeos's guide here: https://www.reddit.com/comments/5b1u99

- Invest in good fronts. I have the ELAC B6.2 and while I don't think they sound like the crazy expensive speakers that some friends have, they sound *much* better than a soundbar/integrated TV sound and are great for movies! Important: whatever you buy, you must buy a center channel that matches the left/right speakers. I have the ELAC Debut 2.0 C6.2 center, with the ELAC Debut 2.0 B6.2 Bookshelf Speakers as my L/R channels.

- Buy cheap speaker wire and strip it yourself!! I'm so bad with practical stuff that I was a bit intimidated by it, but honestly it's ridiculously simple. The guide that I liked before has a section on wires, read it. The sub has its own cable, remember to buy it (I bought the Amazon one).

- Buy cheap HDMI cables from AmazonBasics.

- I have these stands for my fronts: https://www.amazon.com/gp/product/B001PYV7LQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

​

Compared to u/robotdinofight's guide, you lose some sound quality, but only where it matters least and you should save some 700$, enough money to go from the TCL to a LG OLED. Hope it helped!

I'd get a longer sub cable than that( 15 to 25 foot to be able to use the "sub crawl" technique for best bass at your listening position once placing the sub in room. Mediabridge through Amazon or Knu Konceptz if you want a pure copper core cable ( I've used both and they sound exactly the same to me.) Not sure on the home theater power strips being worth it unless they have battery backups built in(debatable that's even needed.) I would also go with Monoprice's Redmere active high speed HDMI cables for longer runs but either way I would avoid Audioquest as they are overhyped and over priced.

Possibly a plain ole subwoofer cable like this if your receiver has the same type of subwoofer output.

If you want to integrate video sources, I would recommend getting a home theater receiver. It will work fine for stereo music and offers a ton of good features.

This is a good choice: https://www.accessories4less.com/make-a-store/item/denavrs730h/denon-avr-s730h-7.2-ch-x-75-watts-a/v-receiver-w/heos/1.html

Next you need some speakers, I’d get these Infinity R162, it’s a killer price on some great speakers. They will play loud and clear and work well for music and movies: https://www.harmanaudio.com/speakers/R162BK-Z.html

Lastly you need a sub, again Infinity has a great sale on this and i don’t think there’s anything better unless you spend quite a bit more for a RSL speedwoofer: https://www.infinityspeakers.com/reference-series-home/REFERENCE+SUB+R10.html

Most subwoofers use RCA cables like the yellow, white, and red to the left. They sell dedicated subwoofer cables that are just high quality RCA: http://www.amazon.com/Mediabridge-ULTRA-Subwoofer-Cable-Feet/dp/B003FVYXY0/ref=sr_1_1?s=aht&ie=UTF8&qid=1464116082&sr=1-1

Hi all -- long time lurker, first time poster.

Anyway, I'm looking for tech help regarding connecting my subwoofer to my speakers.

I have a Pioneer SW-8MK2 Andrew Jones Designed 100-Watt powered subwoofer.

I have Klipsch R-15PM Powered Monitor speakers.

Both are individually powered (obviously). To connect speakers to subwoofer, therefore, I just need an RCA cable. There's a single RCA input specifically labeled for connection to a subwoofer located on the back of the right Klipsch speaker.

Now, here's the slightly odd part. Instead of having a single RCA input on the subwoofer, the subwoofer instead has L and R dual red/white RCA inputs.

After reading extensively on how to connect this (read: booklet that came with subwoofer and internet) I discovered that it's perfectly fine -- and expected -- to use a single RCA cable, plug into the Klipsch subwoofer RCA input and then connect just into the "L" / white RCA input on the subwoofer.

So, I bought this RCA cable: https://www.amazon.com/gp/product/B003FVYXY0/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 and tried connecting the subwoofer to the speakers. Subwoofer clearly turns on, speakers work fine but subwoofer isn't 'firing.' I tried turning volume on subwoofer up, and increasing the frequency to no avail.

Here's the frustrating part: in attempting to resolve the problem, I found myself pushing the RCA cable harder into the "L" / white input and ... the subwoofer STARTED WORKING! However, as soon as I released the additional pressure pushing the RCA cable into the "L" / white input, the subwoofer loses the 'connection,' and fails to continue emitting sound.

So, I figured that it was the cable's design preventing the RCA cable from completely getting a secure connection... so I ordered this cable: https://www.amazon.com/gp/product/B00DI89EZI/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1. I hook it up and it seems that the cable is able to go further into the subwoofer input this time, but, no dice, same thing happens, connect them normally, no subwoofer, but if I go and push the L OR R input on the subwoofer harder and subwoofer works.

Is there something particularly funky about this subwoofer that requires a VERY specific RCA cable to work properly? Or is it that the RCA inputs on the subwoofer are defective? Should I return the subwoofer, or does someone have this subwoofer and know of an RCA cable that works?

Thanks for reading this and taking your time to help a newbie.

Well just go to amazon and grab however many CHEAP HDMI cables you will need. (PC, PS3, CableBox) and you will probably need some standard Speaker Wire and possibly a single RCA for the subwoofer.

You might also want to look into some speaker brackets to mount the energy set to the walls.

You might want to tack on some cables. A sub cable$10 and an HDMI/optical $10 for TV sound wouldn't be a bad idea. Also some speaker stands $45 to put the fronts and/or rears on might be good.

You don't need banana plugs to work with those speakers. You're fine with the bare wire.

After several months and hundreds of dollars I think I'm complete!

Turntable:
Kenwood KD-40R. One day I asked my dad if he had a turntable and this is what started it all. We found it in the attic, original box and in great shape. Replaced the needle and I was good to go. (Minus not having anything else, of course)

Speakers:

• Polk TSi 100 Bookshelf Speakers (Ebay, $100)
  
  Sub:
  
  
• Polk PSW10 (Newegg shell shocker, $80)
  
  Stands:
  
  
• Sanus Systems Wood Speaker Stands
  
  Receiver (hidden behind tv):
  
  
• Onkyo TX-NR509 Network Receiver. This thing is freaking awesome. I got it on sale from Amazon for $150. I control it with my phone, stream music from my phone, run the computer/turntable/game consoles through it.
  
  Cables:
  
  
• Dayton Audio SCP-6 6 Feet Speaker Cable Pair with Bananas.
  
  
• Mediabridge Sub Cable
  
  Preamp:
  
  
• Behringer PP400
  
  

You will need HDMI cables to connect your sources (Xbox, AppleTV, etc...) to your Receiver. Another HDMI cable out from your Receiver and into your TV. And speaker wire to connect your speakers to your receiver. You will need wire strippers.. And an RCA coax cable to connect your sub to receiver

EDIT: Since it sounds like you're a beginner with setting up AV equipment, read through your TV and Receiver owner's manuals. There should be diagrams and hookup instructions.

Denon X1300.

Emotiva B1.

Dayton sub-1200

Many options for speaker wire. If you want plug-and-play (not stripping wires and threading them like a needle) that look nice, $26 for a pair of 10ft. And then a subwoofer cable.

If you need stands, I just made a comment here.

Despite the fact that both speakers seem to be a similar price, the Inclines will considerably cheaper and closer to your budget once you account for cables and a subwoofer (provided you actually need one).

Regardless of what you buy, I suggest first trying the speakers without a subwoofer to hear whether you actually miss the last bit of low frequency sound. Both of my suggestions produce fairly low bass, JBL 305 rated at 43 Hz +/- 3 db and who knows about the Inclines as Def Tech doesn't report frequency response using the standard +/- 3 db (most likely they reach somewhere in the 50s?).

For the 305s, you are less likely to need a sub. Also, connecting a sub to the monitors can be complicated and will depend upon your overall setup. A related issue is whether you will be using an external digital-to-analog converter (DAC) - I recommend you do so for the improved sound quality and that you get one with a volume control. I think the best value approach is buy a pro audio interface - these have a DAC, volume control, and the types of cable connections that would facilitate mating your monitors and sub, plus other features that are used by recording musicians. I have the Steinberg UR22 (paid about $115 shipped new off ebay) but you can do fine with cheaper options: Lexicon Alpha has been recommended https://www.amazon.com/Lexicon-2-Channel-Desktop-Recording-Studio/dp/B000HVXMNE/ref=sr_1_6?s=musical-instruments&ie=UTF8&qid=1472738288&sr=1-6&keywords=audio+interface or the Behringer UCA202 https://www.amazon.com/Behringer-UCA202-Audio-Interface/dp/B000KW2YEI/ref=sr_1_5?s=musical-instruments&ie=UTF8&qid=1472738288&sr=1-5&keywords=audio+interface

I went ahead and got the matching JBL LSR310S, but it is expensive ($400 usually but I got mine new on ebay for $279). It was worth it to me as I work from home and listen to some electronic music. Here are ebay listings now: http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=jbl+lsr310s&_sop=15 Monoprice has a studio sub at $220 that would work (http://www.monoprice.com/product?c_id=115&cp_id=11504&cs_id=1150401&p_id=605999&seq=1&format=2 For cable connections it will depend on what audio interface you get (suggest you buy cables from Monoprice for their support - don't bother with Guitar Center or similar places as their cable prices are very high), however, I think you need the following: for the Behringer you have to use unbalanced connections, qty 4 TRS male x RCA male cables, a) connect the interface to your computer with the supplied USB cable, b) then connect the interface input to the sub input using two (left & right) male TRS x RCA cables, and c) then two more male TRS x RCA (one each, L&R) from the sub output to the 305s input. For the Lexicon Alpha, you would connect in a similar manner but can use balanced connections, total of 4 male TRS x male TRS.

For the Inclines and in considering your initial budget goal, you could go with any of the budget subs. My son has the Dayton SUB-800 http://www.parts-express.com/dayton-audio-sub-800-8-80-watt-powered-subwoofer--300-627 ($99 - $5 Labor Day coupon + $6.95 shipping). I'd spend another $20 and get the Dayton SUB-1000 because it supposedly goes down to 30 Hz http://www.parts-express.com/dayton-audio-sub-1000-10-100-watt-powered-subwoofer--300-628 You would need a subwoofer cable for the connection, such as https://www.amazon.com/Mediabridge-ULTRA-Subwoofer-Cable-Feet/dp/B003FVYXY0/ref=sr_1_3?ie=UTF8&qid=1472740255&sr=8-3&keywords=subwoofer+cable

As I mentioned before, one the nice things about the Incline is that it has a built-in DAC; however, the "manual" isn't very helpful - this review does a good job of explaining the source input hierarchy and how to engage the DAC (there isn't an input selection switch so you have to unplug cables to make sure the DAC overrides your computer onboard sound card - in any case, use the USB input or optical for DAC): http://www.audioholics.com/computer-speaker-reviews/definitive-technology-incline-desktop-speakers-review

It's unlikely Hsu would put his subs on sale. They're what he's known for. You can call and ask him. He answers his own phone, and he's a really nice guy. He might even cut you a deal, if you're buying a sub and bookshelves together. He might not, too. But, hey...might as well ask!

So you're using your phone? If you're using your phone as a source, connecting through bluetooth to your integrated amp or amp/DAC combo, then you won't need anything else. I believe the Elac integrated amp has full bluetooth support. The Emotiva TA-100 has the firmware to support bluetooth, but you have to buy a dongle for it...so, there's another $15 or so.

That should be all you need, though, to get started. There's no end to the money you can spend on audio equipment, once you've decided to develop the habit. But to make music, all you need is something to take the signal from your phone and turn it into an analog signal, something to amplify that analog signal, and something to turn the analog signal into sound.

Oh, you'll need speaker wire. At least 16 gauge...lower numbers mean thicker wire, which means better transmission, generally. But don't go crazy with super-expensive speaker wire. And you'll need a cable to run from your pre-amp out to your subwoofer.

https://www.amazon.com/Mediabridge-16AWG-Speaker-Plated-Banana/dp/B00I52I2PU

You'll need 2 of those.

https://www.amazon.com/Mediabridge-ULTRA-Subwoofer-Cable-Feet/dp/B003FVYXY0

You'll need one of those.

Any audio cable with an RCA connector on each end will work. There are specialized "subwoofer cables" like this:

http://www.amazon.com/gp/product/B003FVYXY0?keywords=subwoofer%20cable&qid=1452159685&ref_=sr_1_3&sr=8-3

The only difference between these and regular RCA connector audio cables is that these "subwoofer cables" is that the subwoofer cables have some extra shielding, which is nice if your subwoofer cable is going to be on the floor with a mess of other cables. Generally worth paying a few extra bucks for IMHO, still shouldn't cost more than $10-$15.

I need help setting up my new setup, I"m a complete beginner to this so bear with me!

I bought the Klipsch R-15PM speakers, hooked it up to my computer via USB. That's working fine.

Then I bought the Pioneer SW-8MK2 subwoofer to hook up to the R-15PM. I bought the 1 male to 1 male RCA cable and connected it to the subwoofer out of the Klipsch and the L input of the Pioneer and it doesn't work.

Do I really need a Y-splitter for the RCA cable? The Klipsch has a built-in receiver, if I read correctly, so I don't think I need an external one. What should I do? Did I connect it wrong?

This one if you can afford it: Denon 1400H

This one if your $1000 total budget is an absolute limit for hardware: Yamaha RX-V383

You will also need speaker wire and a Subwoofer cable

I thought about that ....lol.

Yes his recommendation was 1 or 2 8' subs. Way too small.

Regarding wiring will this be ok for the sub and for the speakers?

Do you know the best place that I could try and sell my soundbar other then eBay or craigslist. I would love to get this system going.

Two mediocre subs are better than 1 good one. I would buy two L12s right off the bat. The F12 is much better than the L12 so if you can do 2 of those then woohoo. SVS subs are a joke now because of servo tech.

Get this http://www.hlabs.com/products/crossovers/index_files/Page384.htm REMEMBER TO ORDER TWO WAY

Get some short Monoprice RCAs (on Amazon)
Remove the jumpers from the pre-outs and main in of your amp.

Pre-out> Harrison Labs > Main in (high pass output) and Subs (Low pass output)

Get some good subwoofer cable too, unlike normal RCA's it makes a difference. https://www.bluejeanscable.com/store/subwoofer/index.htm
Or
https://www.amazon.com/gp/aw/d/B003FVYXY0/ref=mp_s_a_1_1?qid=1465602609&sr=8-1&pi=SY200_QL40&keywords=subwoofer+cable&dpPl=1&dpID=41i%2BDJgkXlL&ref=plSrch

Yep it's a pretty genius invention. Adaptable high pass and low pass. you can more finely tune the low pass on the sub.

Hello, I need a little help. I need two RCA Cable for my JBL LSR305 Speakers that I recently bought. Will either of these Cable Works for Connecting an External DAC/AMP with RCA Out to dbx GoRack? One is Label as Digital Audio Coaxial Cable w/ RCA to RCA Gold-Plated Connectors & The Other is Label as Subwoofer Cable w/ RCA to RCA Gold-Plated Connectors.

Wouldn't I want a single cable instead of a splitter?

https://www.amazon.com/Mediabridge-ULTRA-Subwoofer-Cable-Feet/dp/B003FVYXY0

This is the back of the subwoofer I'm planning to get.

https://i.imgur.com/nB81B6H.jpg

So it has a single LFE input, and then standard L/Rs next to it....if I get a single cable going from Transparent Zero's LFE output to that single LFE input, will it carry both L/R channels?

I'm a little confused if you're saying $500 for speakers alone, or the set up. Heres a list I put together for a friend who had the same budget. Hope this helps.

Just use a single RCA cable for your sub. I recommend [this one.](Mediabridge ULTRA Series Subwoofer Cable (15 Feet) - Dual Shielded with Gold Plated RCA to RCA Connectors - Black https://www.amazon.com/dp/B003FVYXY0/ref=cm_sw_r_cp_api_GS1Syb04D5C47) Your receiver will pull the subwoofer frequency out of the audio information and feed it to your sub, not your tiny bookshelfs. You need to set your front speakers to SMALL on the receiver and the crossover to 120 Htz. This should be done automatically when you set the speakers to small, but just double check. Turn your subwoofers crossover to the highest setting possible, as the receiver is doing the work here. Don't do it twice. Then listen to something, and adjust the sub's volume knob until you can barely hear/feel it. Then you know the volume is correct.

Enjoy!


EDIT: Why are you spending almost twice as much on your sub as you are your speakers? The speakers is where you'll notice the biggest improvement in sound. Start there with your budget, then improve other areas as you see fit. It'd be a shame to see you pay over $300 for a subwoofer and receiver that are fed to $80 speakers.

Just use something like this

RCA to RCA subwoofer cable https://www.amazon.com/Mediabridge-ULTRA-Subwoofer-Cable-Feet/dp/B003FVYXY0

Plugs into the WHITE colored RCA port on the bottom right side of the subwoofer labeled "sub in" the other end plugs into the BLACK colored RCA port on the bottom middle of the receiver labeled subwoofer.

It's okay man, you are just starting out and that's all part of getting better sound. Upgrading is my favorite part because then you can really hear the difference!

Just so that I have it right in my head, the back of your subwoofer has an input for speakers? Does it have an LFE port? How many speaker inputs does it have? What this does is bypass the receiver to manage the sound levels to the "mids" and provide an amplifier to them, then the subwoofer connects to the receiver correct?

Your subwoofer has what are called speaker level inputs. It powers the speakers with the subwoofers amplifier. Most newer receivers (like the one you bought) have line level inputs, which are used to run self-powered subwoofers (which is what I'm assuming you have).

You should really connect the speakers you have directly to the receiver and buy a subwoofer cable that has RCA to RCA Connectors and then connect it to the AVR (receiver) to the subwoofer input. It will sound a lot better.

-Edit- (Depends on if your sub has an LFE output from searching the web for "Canton Subwoofer" it doesn't look like it has one, shit. It might though)

The best thing to do is take a picture of the back of the subwoofer and if possible how you have it hooked up to the receiver.

Nice set up all around though!

I have been putting together a 5.1 system, and was wondering if you would be able to take a look at it! Maybe something you would recommend other than what is here. This set up is a little more than I wanted to spend, but from what I have read about each piece, it seems to be worth it. Any advice is appreciated!


Denon S500BT


BIC America F12


Micca MB42X Center


Micca MB42X BookShelf


Fluance AVBP2 Surround


A few questions I have:

• Are the Fluance dedicated rear speakers worth the extra 50 bucks over 4 of the Micca bookshelf speakers?
  
  
• Is the Micca center speaker a recommended speaker? I didn't see it listed in the OP, but I found it while searching through amazon, and figured that matching the front two speakers was a good idea.
  
  
• I was also looking into the Denon E300, but I don't see any advantages over the S500BT - any advice?
  
  
• What other things will I need to complete this system? Some speaker cable for sure, do I need a sub cord or any banana plugs? It doesn't look the S500 uses plugs, but I figured I would ask.

If I grab the BIC America F12 will I need anything other than this to connect the F12 to my A2+'s?

Yes, but I doubt a single layer of shielding tape would turn this into this.

So I could forgo having to hook up the speakers to the sub and instead use something like this?

https://www.amazon.com/Mediabridge-ULTRA-Subwoofer-Cable-Feet/dp/B003FVYXY0/ref=pd_sbs_23_1?_encoding=UTF8&psc=1&refRID=ZGVMBWB3TDPZXBEGV9JT

And plug that cable into the L or R input and plug the other end in the dedicated sub output on the SMSL Q5 pro output? Or I would still have to plug the speakers into the sub? Or I could just plug them into the amp? Correct?
