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: 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: Plans for 7 Pi and 4 PI Please
Snatch up those 2226HPL drivers! The only differences between the 2226H and 2226HPL versions are cosmetic. Do make sure they're in good shape though, and if in doubt, have 'em reconed with OEM parts. Don't use aftermarket cones. Reconed 2226H drivers...

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...

Re: My 3π adventure
I meant to add some comments about the Helmholtz frequency in each of my responses above, but forgot. It was more important to me to discuss the use of flanking subs and multisubs, and the reasons for needing them. So I became involved in those respons...

Re: My 3π adventure
I like symmetrical multisubs, which is a Welti arrangement. You can use such an arrangement and also include flanking subs.
Place the mains with flanking subs outboard. They are just a little behind, beside and below the mains. They are stereo subs...

Re: My 3π adventure
Measured in-room, I think your response curves are pretty good. This is typical in-room response. Looks to me like all is working as designed.
In-room measurements show the room more than they do the speakers. But having a waveguide speaker really ...
