Splitting Sub signal from Receiver to Wall Plate- Need 1M/2M RCA Cable suggestion...

I need to split my Sub signal from my receiver to a wall plate for 7.2. Does anyone know where I can find a decent quality 1M/2M RCA (or Digital Coax) cable? I'm thinking I need ~2'.

Radio Shack. Lowes, BB, CC, Wally World, where-ever!

Quality of cable is not so much an issue for sub signals. Spend as much as you like, though!

Sorry but it will still be 7.1. By using 2 subs, you don't get an extra discrete channel of information, you just add a 2nd sub playing the same .1 material.

No, I understand that the receiver will still only decode up to 6.1 channels (Denon AVR-1082), but the setup will be 7.2. Regardless, I have been told that what I'm looking for isn't usually constructed in one single cable due to "capacitance issues." So, I'm just going to go from the Receiver --> regular Digital Coax --> 1F/2M Y-Splitter Cable --> Wall plate.

So how are you calculating the .2? Number of drivers? Number of amps? Number of amp channels? Number of enclosures? Just curious. I use a single pro amp running in stereo to power a pair of 15's. Is that a .2 since I use 2 amp channels and/or two subs in separate enclosures or .1 since it is a single amp? How about my upgrade to four 18's (1 pair in each enclsoure) but my amp running mono? .1 (single amp channel), .2 (2 enclosures) or .4 (4 drivers)?

I got my splitter from Radio Shack. The cheapest that they had. Works great.

Not to sound defensive, but I'm defining it as I've learned from other people/companies to define it; 2 separate subwoofers = .2. Axiom comes to mind as an example- they sell complete systems up to a 7.4 setup
(7 speakers/4 subwoofers.) My receiver is only capable of decoding up to 6.1 channels, but can process that info into 7.1 channels; it splits/matrixes (is that even a word?) the rear into 2 channels. So, while I cannot decode 7.2 channels of info (or even 7.1, really), I can do more w/what I've got and enjoy a "7.2 setup". Your system sounds bad@ass (multiple 18's must be insane!), so I'd love to hear/see more if you care to share. Thanks for your input thus far.

Back to the question at hand- I think I've found my solution, so thanks for your help!

Re: Splitting Sub signal from Receiver to Wall Plate- Need 1M/2M RCA Cable suggestion...

Your both right.

Anyway, here's the best option.

Use RG-6 coaxial cable, with either direct rca compression connectors or a compression f-connector along with a screw on rca. Screw on rca's are not easy to find.

Cheapest, solution to get a high quality cable. Trust me don't use cheap cables on your sub unless it is a cheap sub like a HTIB sub.

Also try not to use a y-splitter. See if one of your subs have an output for daisy chaining.

Another little tip would be that if your subs are not exactly the same, don't do the .2 thing. I mean they should be the exact same size and model. Different companies tune their equipment differently. You may be able to get louder bass, but if they are different subs, I would say the SQ will go way down.

dont' use different size subs at the same time unless you can cross them over properly.

Nope, they'll be he same sub; 2 SVS 20-39pc+'s. I've been advised by SVS and others that using the y-splitter was the way to go. In any case, thank you all for your input. If it weren't for great folks like you in this community, I'd probably just be rocking out to some cr@ppy Rat Shack HTiB vs. realizing this incredible dream.

Both of these are poor suggestions. A cheap Y-splitter will have exactly the same audio quality as a $400 quatrz-tuned cryogenically treated solid silver wire with gold plated connector, with magnets all around it to "stabilize the aura" of the sound.

It's a subwoofer, not a radar system.

Now that was funny.

heh heh. skyooooz me, but I was feeling cheeky. It just bugs me to death that folks always think that spending more money gets a better product.

This might be true for some things, but honestly speaker wire is just wire, a shielded audio cable of any kind is perfectly fine for the low frequencies of a subwoofer, and all power cables are identical.

If you want nice looking, sturdy cables with connectors that don't oxidize, please visit some of the sponsors of this site. I hear good things about them!

So you guys are telling me that this guy should use 10 dollar cables with his really nice SVS subs. That's great advise. When custom cables cost a few dollars more from any home theatre installer.

No, we're not telling him that at all. If he can, he should spend even less than $10 on his subwoofer cables. You see, a subwoofer signal is mono and degrades very little over short runs. So unless he's sitting in the livingroom and his subwoofer is in the basement, then, it doesn't matter to spend all this extra money on super duper cables. I would argue that there's never any reason, but, someone will always think otherwise. Live and learn.

New Question!

How about VGA cables? I need to run 40' of VGA from my projector to future HTPC. What cable would you guys recommend? Would there be any signal loss for this distance? If so, how should I go about achieving this?

Not at all. I said more expensive cables would not improve the sound quality; that is a simple fact of physics. I later amended my facetious post by saying that if he would like cables that are attractive and do not corrode (as do most Radio Shack cables) he should visit the site sponsors.

sheesh, don't get your panties in a wad! we are permittd to be a bit silly occasionally, and always permitted to voice opinion. I prefer saving a few dollars on boutique cabling and instead spending it on better speakers and gear.

Have a nice day!

Monoprice 50' super VGA, gold plated and in-wall rated for $15.20.

But instead of an HTPC, why not use a dedicated media player? There are a lot on the market that will play DVD .iso files, most other video files, display pictures and play music stored locally or on the network. The Popcorn Hour Media Tank has received some great reviews. It is smaller, easier to use and comes with a remote.
