Options in a nutshell
It's all about the midrange, when you're talking differences between the JBL 2226 and the Eminence Omega 15 in the four Pi loudspeaker. The Omega 15 sounds very good, powerful yet still natural sounding. But it isn't as good as the JBL woofer. The 222...

Add subs for extension and modal smoothing. I'm sure you saw this whitepaper already, but just in case:

Re: Subwoofers
Two subs are definitely better than one.
I wouldn't suggest driving them with tubes. You could, but I think it's a waste. Wrong tool for the job, in my opinion. Use tubes for mains, solid state for subs. Use plate amps for the subs or press an old...

Re: 3pi/ 4pi plans
Stands are good for raising the sound source, particularly for smaller speakers. I think it becomes less necessary with larger speakers, and sometimes I use stands that are short enough they are probably best called angled risers. But sometimes even la...

Re: Multisubs
I personally use a Class A FET amplifier, the ProFet amp from Selectronic. This requires a low-pass filter in front of the ProFet amp, and I have played with several types from passive line level filters to various off-the shelf devices.
The one I ...

Re: Multisubs with Seven Pi corner horns
Without the right corners, I'd go with the three π or four π models. That's what they're designed for.
Of course, I'd suggest the optional JBL or AE woofers. I think you've seen from the measurements that there's no breakup up high with them and res...

Re: Multisubs with Seven Pi corner horns
Yes, I've used subs (actually multisubs) with cornerhorns. This is the best sound system I've ever heard, but you have to have a room with the right corners to do it.
With my DI-matched two-ways, I usually run what I call "flanking subs" so...

Re: 2-Pi Tower floorbounce
That's key - Floor bounce interference manifests itself not only by the distance from midwoofer to ground but also the distance from source to listener. At 6-8 feet, it's around 150Hz.
The thing is, while you could smooth the notch with multiple soun...

four π speakers + multisubs
When I don't run subs, I always position the woofer close to the floor to avoid floor bounce. I recommend floor standing or angled risers or no more than a few inches, if subs aren't used.
If subs are used, then I usually put the main speakers on a st...
