Bag End Quartz/Crystal rig. Anybody know it? Comments?

Re: Bag End Quartz/Crystal rig. Anybody know it? Comments?

I've heard 6 or 8 of the Quartz subs powered by PL380's. It was ok, but I don't feel that it was any better or worse than say, the same number of SRX728's, SB1000's, SB850's, etc. in terms of both output and tonality. I wasn't all that blown away. I *think* they are loaded with some variant of the Eminence Sigma 18.

They can't be very efficient... their whole "gimmick" is using a sealed box and then applying a lot of corrective EQ to achieve the LF corner they want. I'm sure that works well, but you'll probably need to bring a lot more sub than you'd expect.
