I've been workin' on that for years now. The Bellari "sonic exciter" was the end. It's got a couple of 12AX7's in it and really helped the sound. Before I would just get the clip lights blinking and then shut it down 'cause it just was loud. With the Bellari I could do the same thing except it sounded so good I could just leave it there until the speaks melted.
It's a baby pro sound setup with some car audio stuff. The 2 half kilowatt A500's feed the Beta 10's and the car amp sends 25 watts each to the co-axial compression drivers. A quarter kilowatt plate amp powers the 12 inch 94 dB/watt sub. Active XO separates the signals and the EQ notches out the resonant peak on the Betas.
But it's the Bellari that makes it sound like bliss. It's that damn thing that got me into the tubes!
It can get really loud. I've never had a problem with the neighbors though. That's what's amazing. I have cranked it to clipping with the big door open and when I walked out to the property line it wasn't that bad. Oh yeah, you can still hear it, but the sound of a car driving by covers it up. And it's not like I leave it cranked all the time. I will "clip out" a song or 2 and then go back to backround level. With the big door shut I don't think anybody would care as long as it wasn't dark outside.
And it takes up zero floor space -
