it's the tweeters on top and bottom that IMO have the most effect, and those will work fine even without a back wall.

Ummm, John?
The tweeters are on the beveled fronts/sides. It's the woofers that are top and bottom. Lift one off your soup can and check!
I think John is right though in terms of it sounding OK. The QS series are really flexible in terms of mounting location!

My tweeters aren't immediately near a wall, front or back. They work pretty well.

Bridgman, as always cool info. Just had a lengthy phone conversation with a friend that is way beyond my level of knowledge with this stuff. He suggested something similar to what you were talking about, although adding a bit of a twist. Run speaker level inputs to the sub, tell the receiver 'no' sub, and set bass management for the fronts to 'large.' He seemed to think that the LFE info would be redirected to the mains. Then I could use the sub's crossover to match the 22's. The twist comes in the form of soldering up a hobby box with some caps that would limit freqs to the mains and have something like a 6dB rolloff. I see that there could be many different options and hours of listening. It is fun though to tweak with things just to have something to do.

And ahh yes, powerwindow is my tribute to the greatest rock trio around and I'm from Los Angeles.

Thanks all for the QS placement info. I don't think I'll worry about where they'll go. I just need to win the lotto or something to get all this off the ground.

Tom, as John B.commented, my view is also to just keep things simple. Although the 120Hz cross is higher than ideal, use it with all speakers small, sub on and the line-level connection from the receiver. Use the bypass on the sub's internal crossover so that there's no problem with it.

>>Ummm, John?

Um... yeah... I meant the big tweeters... with the cones... yeah...

Good catch. I don't have to check -- I trust you

Yep, that's the idea. Just be aware that most receivers do *not* seem to redirect LFE to the mains. I know my receiver (HK) does not, for example. I believe Yamaha receivers will redirect LFE to the mains, not sure about Sonys.

I definitely am all about keeping things simple and that would be my first choice of connections. Chances are I will not be able to localize the sub anyway. I'm assuming that the reason I would want to keep the sub as close to the TV as possible is so that explosions or whatever, don't seem to be coming from off screen. Similar to why you don't want to be able to locate your surrounds.

What about music listening. I do know that if I have my receiver set to "auto decode" in the sound field/surround setup that it will direct low frequencies to the sub if sub is chosen in speaker setup. In that case sub placement is not critical, but the soundstage up front may appear funky because again you don't want to know where these lows are coming from.

Hope you Canucks had a good Canada Day.
