Re: long wall setup
As much as I love constant-directivity cornerhorns, I'd probably run three π or four π mains with three π flanking subs and possibly one or two distributed subs in your room.
I've run constant-directivity cornerhorns at each end of a long wall in room...

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: Horn loaded Corona Build
Truly excellent.
I hear you about subs that are smaller than the midwoofer in the mains. It just seems "wrong." And you can get higher efficiency from a larger sub, so there's definitely an advantage in using a larger subwoofer.
But the...

Re: Crossover slopes
It's really just a guess without measurements. But it does sound like they intended to run the subwoofer up pretty high to match their mains. So it might just work as a flanking sub.
One thing you can do without measurements is to run the sub by its...

Crossover slopes
Hi Wayne,
There are a couple of old Triad subs in the house that were purchased back in the 1980's. Pulled them out to sell them but figured they might do OK as flanking subs as they aren't too large and would fit in my living room. Don't know their c...

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: 2 channel reinforcement subs
Look up threads on "flanking subs." Basically, you run the subs pretty high, with a gentle low-pass filter. I like 100Hz second-order. Run the mains full range, so they blend with the flanking subs. Set a sub just beside, behind and below t...

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.
Speakers pulled far away from walls always have the benefit of no SBIR, but...
