It models out liking really small ported boxes...like 3-4 cubes tuned to 38hz. But going bigger and tuning lower yeilds pretty good looking graphs. 6-8 cubes tuned to 35-37 gives a good peak around 40-45hz. Good for competition use.

have you accually heard one of these subs perform?because i have been told that subs over 18" just dont seem to live up to thier hype and that 2 12, or 15,s would give you lots more spl ...although that could have been a rumor how does it sound? but that amp does look beastly if i could afford 600 for 2500 watts i would get it free bump

I haven't heard it myself, but I have heard of some other hitting some good numbers with one of these...

there were only 40-50 made, and restricted to being sold from their top-tier dealers...this one came with an upgraded VC.

3k for a sub, better break a 150 like it was nothing.

I'm in class right now...I'll be back at my apartment around 3 and can take a pic then if desired. This this is really heavy, and I'd rather not have to take it out and put it back in...will this pic be good enough?

It's got triple stacked 150oz magnets, and a 30lb motor/magnet structure.
