MaxxBass is all over the place. In movie soundtracks, to tv shows. Ever hear more bass than you expect? That's it.
New Peavey IPR DSP series amps have the lock on Maxxbass
They are the only amps to provide it. They will be big winners.
Pro audio racks show up with these all the time:

at $2800
The MaxxBass plug-in is $200 - it's not cheap.
Waves has been very careful to market MaxxBass, and this new Peavey arrangement will be killer. The bass playing and FOH will eat it up. No more huge subs to haul around.
For a typical bass cabinet, you need something with good upper bass and mid dispersion to get the Maxx out of it. Most bass cabinets lack in the mids as people have been trying to squeeze out close to fundamental bass. In other words, you're typical bass cabinet may not bring out the best in MaxxBass.
I use pro level PA cabinets. JBL and pro companies will publish polar dispersion charts. Because in the real world dispersion is important.
There apparently is some misconceptions about MaxxBass that people will have to get over. It is a tool for live use also.
