For sale is a single or pair of one of the best Devastator designs available. The Beast Mode Devastator 21 Stepped Version 5. This design produces massive amounts of bass which you can see in the third picture.
You can load it with a Lavoce SAN 214.50, Eminence NSW 6021, or a few other 21's on the market. Feed each Dev with 1000-2000 watts and it will blow you away.
These are 60" x 32" x 24" each made of 18mm baltic birch plywood. Different models of the Devastator can be made upon request.
Meticulously modeled in Fusion and CNC cut. These are designed to be put together with minimal tools and much quicker than your ordinary sub enclosure.
I have two of these in our theater that can be demoed for serious buyers.
Each flat pack without a driver is $1500
Assembled and finished with Duratex or laminate veneer in many colors or wood grain is available for an extra fee.
I also can make sealed subs in any size for any driver.
