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 agree with you generally about almost everything you said except the part about time alignment. This is impossible in the modal region.
Outdoors, you want sound sources acoustically close together - within 1/4λ of each other - and the electrical si...

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 ...

Re: Small Room Suggestions
All my speakers tend to work well with boundary reinforcement, so half-space or quarter-space is best. Of course, that then gives SBIR but that's what flanking subs mitigate.

Re: Plate amp for 3pi subs
The SPA250DSP plate amp will work just fine, and yes, you'll need the DSP version for flanking subs because it will allow you to set the low-pass filter to 12dB/octave. It will also work for distributed multisubs if you decide to add one or two of those...

Oh my God, that was funny! But seriously, I'm just a big fan of Welti and his pioneerinng work on multisubs. And your visit with him was really good. I enjoyed it.
