Re: Retrofitting Altec 612 cabinet for a 4pi build
I wouldn't change the dimensions of the cabinet for these reasons (from the Pi Speakers FAQ): Cabinet design, port placement and internal standing waves Damping material placement Altering Dimensions I realize you are talking about reducing the inter...

Re: 7Pi questions and plan
You can place sound damping materials on the walls, in and around the corner and anywhere else you want. They'll absorb sound mostly at high frequencies and upper midrange, depending on how thick the panels are. So the sound radiating from the bass bin...

Re: 3Pi plans and questions
Certainly, a person can always employ the single-sub route. But to be very honest, this is a worst-case scenario. You really want to use at least a pair of subs - setup as flanking subs. And if possible, add one or two more distant subs configured as ...

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: 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: Multisubs for pi7
I run two sealed Stereo Integrity 18s in custom boxes with my Pi7's. I run with a single Behringer NU12000. I will replace with a big Sinbosen amp in the near future. Works very well!
