The footprint and the look resembles my M&K X10 series subwoofer. Even the unpacking method is the same. LoL. The difference is the 2nd driver location. Hsu Research goes for the front and rear while M&K is front and bottom. All push-and pull design.

Looks promising. Now need to see the measurements hehe. Does data bass still actively do the bass measurements?
