Is that using the XBL 2^ motor?  Is that your driver?

That woofer looks like it means business. Will the 18" cube be sealed, PR, or vented? What kind of power does the amp put out?

Denny
The driver is not XBL^2 motor but there is one in the works.
Still a very good driver for the money.
The driver is a CSS driver which we work with Bob at CSS and we are selling the drivers,amps as well as finished subs.

Jack
Sealed is best with 6db of boost around 25hz.
We are working on a plate amp to offer a very good plate amp for the finished sub.With boost adjustable as well.

Thank Will for getting the data over just not fast enough.
