Not to mention you will find yourself strangely lusting for Hummers. Do it once, do it right.

But it sounds good now.

Center 1st.
The QS4's will surprise you.
Go big.
Be happy.

P.S.
M80's are amazing

H1 or bust...

What did you decide?

To start off with, I'd stick to 5.1 and use the money saved on the second surround speakers to upgrade to QS8's, one of the larger centre channels and/or an EP500 sub or competitors equivalent. You can always upgrade to 7.1 at a later date if you feel like it without compromising on your main components up front.

For me it would depend on how far your sofa is off viewing wall.

If you follow the rule of thirds for standing waves, your sofa should be about 12' off the front wall. This puts your surrounds at 12.5-14 from front and only leaves 4-6 feet of breathing room for your rears. Not ideal.

Too small to take advantage of 7.1 imo.... rears will smear into surrounds and become indistinguishable. Soundfield collapses.

Wouldn't consider at less than 20+ feet or so.

+1 for putting saved dough into good center channel!

Good luck.

P.S. those are nice room dimensions for acoustics. lucky.

Almost ideal golden rectangle.

My room is almost identical in size.
It has 2x 7.1 setups wired from one reciever.
No regrets.
Maybe one, I want better speakers.
Axioms stay.
