It's nice to see the constant drive towards different designs, even if horn loads have been around a while.
Just put 100 woofers in the home and don't worry about all the different designs, let the mutual coupling amaze the natives.
When Rockford Fosgate showed off the new 15kw car amplifier using
Ultracapacitors, people were in awe at how it delivered this uber power
with one car battery on a trickle charger.
The amplifier IS running all (60) 12" subwoofers in the demo room with channels 3&4 bridged at 1-Ohm! Channels 1&2 run all (16) 6x9" for high end.
The amplifier is a FULL-RANGE amplifier a Class A/B circuit design with new Hybrid Technology and 140 Volts of storage. To produce this much power utilizing traditional Class A/B technology would require 2,000 Amps of current whereas the Power T15kw utilizes 500% less current to produce the same amount of output power.
You'll hurt yourself trying to figure it out ... This WILL change the way mobile audio amplifiers are designed. Several competitors have been in the Rockford Fosgate booth (I can't name them but the one sounds like STICKER and have been here 4 times scoping out the technology - and another has two initials in their AUDIO title) congratulating Tony D. the engineer that someone "finally" provided a new circuit solution for the car audio industry.

Could it be that 60 woofers in a room by itself is impressive
There is low frequency coupling from the drivers themselves to boost
SPL. This trick was used to make their amplifier look better than it is.
They didn't use sonosubs, no IB subs, no horn subs, etc., just a bunch of woofers in a box
