Re: L/C/R placement and toe-in
There is nothing wrong with bringing them a meter or two closer together, provided they are still outside the seating position. I think your main considerations will be the side wall and front wall reflections (which can be mitigated with flanking subs)...

Re: 3Pi speakers - various questions
Can you put the subs just to the outside of the mains instead?
If you put them in the center, they'll act as a single source. Three feet of separation isn't enough, except to smooth self-interference from nearest boundaries which you won't have becau...

Re: Six Pi Review
Understood and agreed. I think most people familiar with the multisub concept know that the more bass speakers you use, the smoother the modal range becomes. And under 100Hz, it almost doesn't matter where you put the woofers if you have four or more...

Re: Six Pi Review
As an aside, measurements made in a trihedral corner outdoors naturally do not show room modes, the response down low is ruler-flat. But indoors, room modes take over and make hot spots and dead spots, causing ripples in response. I'm sure in your case...

Re: 3Pi speakers - various questions
Thank you Wayne.
We are lining the entire 4 (of 6) room surfaces with panels similar to the range of low frequency control devices such as panels from RPG (look under the "low frequency" tab), and the Primacoustic Maxtrap. We are also refe...

Re: 3Pi speakers - various questions
Surface treatments are useful for reducing reflections from about 300Hz upwards. But they do not work at bass frequencies, not at all. You can't get a surface treatment to work much below midrange. It would have to be very thick - like measured in feet ...

Re: Built in speakers
If the speakers are high quality and mounted in the right place, in-wall mounting is very good. It eliminates self-interference from the baffle wall (which is almost always the most offending reflection) and removes any possibility of baffle step.
Baff...

Re: H290C Horn/Waveguide
Some have asked why it is important to maintain 90° beamwidth in the horizontal, and why 100° or more is less desirable. For example, one of our friends here recently evaluated another similar waveguide/horn with ~100° coverage. The other horn was tout...

Re: 7 PI Plans
Bass response of the seven π cornerhorns is the same as the four π speakers. What's different is the behaviour of sound at frequencies above midbass. The corner loading of the woofer and the midhorn prevent any self-interference from nearby boundaries,...

Re: How does one emulate the typical theater sound?
You're absolutely right. With a projector and screen, you can put the center speaker behind the screen. That's definitely the best approach. When running a plasma or LCD screen though, I'd have to say I don't think there is a good center channel optio...
