Reddit mentions of 100 Feet 14AWG Enhanced Loud Oxygen-Free Copper Speaker Wire Cable, CNE62761

Soundbars are pretty awful. If you are determined to get one, just Google it and get whatever.

However, you should really consider a stereo setup instead since you have a reasonable $1,000 budget. It would be a shame to pair your high end TV with garbage audio.


Receiver

Speakers

Speaker Wire

Ok. SO, a couple points of note.

• This equipment, especially the subwoofer is VERY VERY undersized for the size of the space that you're talking about. That's a HUGE room. I just want you to know that up front so your hopes aren't too high with this. That said, this is free equipment and you'll probably LOVE it.
  
• That Receiver is/was a very nice receiver for its time, but it is now old and sliiiightly outdated. While the receiver will passthrough 4k resolution, it is not compatible with 4k/60fps, it will not pass through HDR/Dolby Vision/HLG. Again, I doubt this will be a problem for you, but I want to mention it.
  
  With all that out of the way, I will address your questions directly.

  > I have gone to sites like Crutchfield in an attempt to learn what cables I should use, and it seems the most recommended cables would be ones with 14 gauge, and banana ends (I think that’s the term). I have seen spools of 14gau wire on Amazon as well as banana ends that are DIY to put on the wire. Should I pick those up?
  
  
  Amazon. Just get oxygen-free 14-gauge Speaker Wire. Maybe even a 100' spool and a 50' Spool. It's not expensive, and it's great stuff. You can even go cheaper with the AmazonBasics brand. It isn't oxygen free pure copper blah blah blah but It's even cheaper at $16 vs $27 for 100'. Your call, you likely won't hear the difference. But I like the peace of mind for $11
  
  Personally, I really like banana plugs. It makes things SO much easier to hookup, move around, plug and un-plug, and ESPECIALLY really helps organize things in the back of the receiver. After trying several brands, MediaBridge is my absolutely favorite. Very easy to use and very secure. $26 will cover every speaker wire, both into the back of the speaker, and into the back of the receiver.

  > What about the subwoofer? Is there a different type of wire I’ll need for that? Can you buy PolkAudio power cables for that type of woofer? What should I expect to pay for cables?
  
  
  The subwoofer power cable is basically a generic PC power supply cable. Here is one on Amazon for $7 shipped, prime.
  
  ​
  
  For getting signal to the subwoofer, you need a single RCA male-to-male cable that will go from your receivers LFE pre-out, to the sub. So you'll need to buy a sub signal cable in whatever length you need to get from receiver to wherever you place your sub. In any case they are really affordable. I recommend AmazonBasics yet again. 25' cable for $10 here! They are pretty and very high build quality for the price.
  
  ​
  
  SO, to summarize you could have this all running for say $60 or so, plus whatever HDMI cables you need :)

> seating for 8 persons

That means you have seating off to the side, likely diagonally, correct? What this means is that you should get bipole/dipole/radiators for your side-surrounds, and place them centered between each "row of seating" (if it's additional couches instead of seats, put them centered based on distance from furthest seating to closest seating), a pic/drawing of the room would help. Good ones that'll fit in your budget are these bipoles ($120) or its bigger brothers, this one ($150) or this one ($200, I have these, got them $100 on sale from Walmart, currently normal priced).

> I preferred the quality of Klipsch

As for your front 3 speakers, two options I have would be Klipsch, or the same company as those bipoles. For Klipsch, there are these bookshelves + matching center ($340); for Fluance, they don't have a matching center for their SX Series, so you can mix and match, or not get their SX Series, their most expensive series (Signature) bookshelves + center would be $350, so similar price to the Klipsch's, their 2^nd highest model line bookshelves + center would be $270.

For your back-surrounds, are you wall-mounting? If your are, you will want front-ported speakers. Ones that I can recommend are these Sound Appeals ($70), or actually Fluance's top 2 model lines, you can get the Signature Series ($200) or their XL7 Series ($150). You don't want dipole/dipole/radiators for back-rears, as the sound dispersion wouldn't be good (null zones or amplified zones)

Now, that brings us to the subwoofer. If you were talking like 3-4, maybe 5 people, you could just get 1 sub, however, since you are talking 8 people, you definitely want 2 subs. The reason for that is a subwoofer has sweet spots, and an 8-person seating area is definitely too large. With the speakers I recommended, if you went on the most expensive of my recommendations, that would leave us with ~$750 to play with. I would recommend two of these ($660 total) or two of these ($740 $865 total, too expensive).

Now, I'm guessing you'll also need speaker wire. I'd recommend getting at least 16 gauge (lower the # the better), and if you are going in-wall, get oxygen-free. Speaker wire is cheap, here is 100ft of 14 gauge oxygen-free speaker wire. Now, I'd also suggest getting open-screw banana plugs (likely wont fit on any speakers you are wall-mounting), just to save on some frustration with connecting the speaker wire to the speakers/receiver, I bought 2 orders of these ($16 total), they connect like this. You will also want 2 subwoofer cables (RCA's with better insulation), I bought 1 order AmazonBasics in 15ft for $9 ($18 total for you), they also come in 25ft ($20 total, so better safe than sorry). If you don't know how to place a subwoofer, here is /u/zeospantera's tutorial.

If you're going to buy nice speakers and a receiver that are expensive, why cheap out on what connects them? I would personally go with a 14 gauge oxygen free copper wire and some banana plugs. Links below to the stuff I have, and I didn't think it was too expensive.

I have the HFBP's which looks to me like basically the same thing but the newer model.

I just measured the template and used some wood screws and screwed the one side into a stud and the other side into drywall. It mounts up fine. and there is enough room for cable to come thru.

I drilled holes and fished the cable, but there was not enough room for banana plugs so I just did it the old fashioned way. You can no doubt have enough room to have the speaker wire hanging out and running down the wall or whatever if you need to unless you are using huge wire. I am using the 14 gauge here:

Hmm.. here are the plugs: Monoprice 24k Gold Plated Speaker Banana Plugs, Closed Screw Type (5 Pairs) https://www.amazon.com/dp/B0097JLQVC/ref=cm_sw_r_cp_apip_86k8QtboC1QsA


And here is my wire: C&E 100 Feet 14AWG Enhanced Loud Oxygen-Free Copper Speaker Wire Cable, CNE62761 https://www.amazon.com/dp/B009EADB2Q/ref=cm_sw_r_cp_apip_Sy9NGh8nFOROC

Do I have to fan it out so it's really spread out ? Like no wires bunched together ?

Yup, those are mine as well.

Same type of wire as well just 12AWG(14 is fine though.)

>Do I have to fan it out so it's really spread out ? Like no wires bunched together ?

Exactly. Plus make sure you're threading the 2 parts together gently with your fingers at first then apply more force once you get past the threads to the flat part with the wire. I check them once a month or so to make sure they haven't loosened up which is common for banana plugs. Not a big deal. Just tighten them down and go back to business.
