Re: 3Pi plans and questions
You've got mail!
You can buy waveguides and crossovers from us.
I wouldn't suggest modifying cabinet dimensions unless you can do acoustic measurements to verify there is no regression from the changes. The thing to watch out for is lower-midrange...

Re: Concrete and Tin
It's probably not the best. I would expect problems at low frequencies from room modes and also midrange and higher frequencies from lively reflections. Not sure about the roof either - hopefully it doesn't vibrate and buzz.

Re: Number one mistake?
You know, architects aren't usually focused on acoustics. They have a lot of goals and acoustics is a property that is generally way down the list, if it is even considered. And it usually isn't.
Sadly, even venues designed for entertainment often h...

Re: speaker plans 4 pi
That's awesome! Hope it was a good deal for both you and the seller.
The deal with the center channel is the port can be removed for aesthetics. There isn't a benefit when doing so, in fact, there's a slight penalty. But only slight. The spectral ...

Re: Am I in the Right Place?
Going a little larger - to 5ft3 - adds a smidge more bass and remains properly damped. You can model it and see what I mean, or build a physical model and measure it. Going smaller reduces bass output, but again, remains properly damped. So that's a u...

Re: Subs for floorstander and corner horns
There are two different answers to what are really two different questions here.
One is whether subs are needed for six Pi and seven Pi constant-directivity cornerhorns. The other is whether subs are needed for two Pi towers.
They're two different...

Re: Multisubs for pi7
You are correct that subwoofer phase in a small room isn't terribly important. The phase response of the subwoofer is swamped by room response below the Schroeder frequency, around 200Hz.
I don't care if you use sealed or vented direct-radiators, or ...

Re: Multisubs for pi7
I love basshorns, but they're just so big. Their size often makes it inconvenient to use hornsubs for multisubs.
The main benefit that hornsubs offer is maximum acoustic energy. But we really don't need maximum acoustic energy to make it ear-shatter...

Re: Subwoofer amp and crossover
I would suggest using a flanking sub approach. Do a search for "flanking subs" here and on the internet at large. Lots of good information about it.
To describe in a nutshell, flanking subs are basically stereo subs with specific placement...
