Yep, I want to go even smaller and lighter. I have access to some of these 1" x 25 units. Specs and polars charts are in PDFs at bottom. They claim 96 db and 10 to 250 watt rating crossed at 120 (no way but I will do 250 or so.... Thoughts? I could even do 50 of them??? I can get them at a real bargain price.

I am thinking medium levels (a single act but I do play left hand bass) I am planning on a Hypex DSP amp, and building a 6" Tang band "sub" cube sub with a passive radiator, perhaps iso stacked . Its about size . I want a Hoffman's iron law breaking pa (-: I will choose to lose the "efficiency" and use amp power as much as possible. Steep crossover slopes to protect the little 1" units, though they claim a lot of power handling.... don't need anything below 60hz, just a decent level. I see a lot of these crossed over a bit higher than 250 as well
25 1" drivers crossed over steeply no lower than 250 ought to be pretty loud huh? My B&W 801s use a 5" mid and yes, they could be horribly misused as a PA in the places I play. (That would be a travesty)
Well, ideally we want a pristine 250-2500 Hz telephone BW, so nowadays with digital; 4th @ 125 Hz or 62.5 Hz/8th, but an added 720 degs of delay [2 Hz offset] runs counter to my 'sensitivities' even if not a big deal down this low, so would try the pioneer's conclusion that up to 500 Hz/2nd order was the best overall compromise.

I was thinking I could get away with 24db and some time tuning so I could push those 1" drivers harder, definitely going between 250-350, but you and the pioneers are probably right, we don't want the emasculated "B***" drive a truck through the hole sound. I will be able to tell when I get those 25 x 1" sticks and hear them. Thank you
Any other thoughts let me know I don't mind being dumb and educated. (-:

That's exactly what I planned to do as per post 6. Going to use one of those (Hypex)? DSP amps to biamp and do the eq etc. This is where I think I can "fudge" Hoffman's law, sacrificing efficiency. Just wanted input before a few hundred go bye bye .
FWIW, I'd avoid the Tang Band mini-subs for PA use. Seriously.
I had a pair set up in a medium-sized living room, and was past -6dB on an NU6000 to get to decent levels. Those things need a rocket up them to get anywhere useful.
My recommendation would be to grab a couple of half-decent 8-10" drivers and put them in a 6th order bandpass.
There are other problems with small line sources, too...

(~150/side sometimes) wonder how they would sound in a little home setup ? A 5" neo PRV on a horn would be more sensitive (but limited in bandwidth)

here's frequency response at 6 meters of what appears to be the same speaker. (assume this is vertical -?)
