I have TWO Prototype Dr. Bass Cabinets that were built in 2004 for NAMM in LA. Both are 3-way with "light weight" being the selling point. They use "standard" Eminence Components but they've never been strained. i have on a few occasions used them as side-fill cabinets. SOLD - [DEL]One is a 12-6-T Air Head - I think Mark later called this model the 1260. This one is 8 ohm with the Truck Body Liner (One of Mark's best ideas). It's cosmetically perfect on the outside, and never been opened. The only "defect" 2U clips on the side ripped during the airplane ride (an amp head was installed) - I never put them back.[/DEL] The other is a 10-8-T [DEL]Air Head[/DEL] "Standard" - i'm going to guess a 1080 - also 8 ohm with the Truck Body Liner. It's also cosmetically perfect on the outside, and never been opened. $210 each (obo) + actual shipping. Pic's will be posted when they arrive!
