I'm considering purchasing a 5.1 receiver and then adding two JBL WEM-1 wireless kits (50w x2) for the four surround and back speakers. This would turn a 5.1 into a 7.1 (sort of). With two wireless kits, I could essentially wire the Surround Left and Back Left together, and the same for the right side. This would make every 5.1 audio format 7.1., and make the wife happy because no wires running across the room. Thoughts?

It won't be 7.1 because even with synthesised rears a la PLIIx you still have different signal to the rears than the sides. Buy a 7.1 AVR, which they almost all are these days, and use the wireless kit for the rears. It still might be a better and not much more expensive solution to get cables installed to run to the rear speakers.

I have to agree. It wouldn't even be "7.1 sort of", but more "5.1 with two extra speakers miming the two sides." You wouldn't get any imaging advantages of 7.1, the sound quality won't be any better, and I wonder if you'd hear any difference at all over a standard 5.1 setup.

I'd just go 5.1, use the wireless system if you need to do so to eliminate wires, and call it a day. It'll be more cost effective (two less speakers, one less wireless unit to buy), and you'll get the same benefit.

If it were me, I'd use the money saved to get a 7.1 receiver and take advantage of some better features. Most 5.1 receivers are fairly low end (from the typical brands, anyway.) You can always turn off the surround rears in a 7.1 receiver and it will work as a 5.1. Then if you're in a place that allows true 7.1 (and the wife comes around or you find a way to fish the wires through the walls), then you already have the receiver for it.

Here's my living space. Does this help? Sorry it's so crude. I did it in paint.



Yes, it's an odd location for a TV., but that's another story. The TV is anchored to the wall and swivels in every direction, so it's easy to angle it no matter where you sit.

Yeah, your 5.1 is awkward enough there. I wouldn't try 7.1.

Wouldn't adding a speaker in the corner (bottom right of photo) create a better sound? If not, how come?

Well, I haven't seen a new 6.1 receiver for sale in some time, and 7.1 receivers don't have that capability (that I know of, and I've owned a couple.) So you'd have to buy an older receiver.

It's not just throwing a speaker wherever that adds to sound. 5.1 and 7.1 systems are arranged the way they are for proper imaging of surround sound. Otherwise it's just disjointed sound effects.

If you draw a centre line perpendicular to your TV screen, it will stretch to the corner between the couches. Which means a 5.1-speaker set-up, like the one in your drawing, will have the surround speakers forward of all the listeners rather than "surrounding" them. Probably wouldn't hurt to place one or two speakers in the corner between the couches. Surround localization will be off, as Tulpa alluded to, but at least the speakers will be surrounding the listeners.
