Swarm subwoofer system VS DEBRA Distributed Enhanced Bass Reflex Array

Does anyone has any opinion or listened to either of these systems?
Would appreciate any response.
They are functionally identical.  The difference is the footprint:  The Swarm has a square footprint, 12" x 12", and the DEBRA has a rectangular footprint, 13.75" x 9.5", which "hugs" the wall a bit better.  

My DBA is DIY and very similar to both of these. Same Dayton SA1000 amp, somewhat better Morel 10" drivers, squarish cabs. https://systems.audiogon.com/systems/8367  Based on my experience, the advantages of going to a four sub DBA are so great, and the differences between all these so relatively small, you can be assured of excellent sound quality, set that issue aside, and focus on practical considerations like size and looks and features. 

Duke also has a kit you can assemble that looks to be first rate finish and one helluva high value deal, if you don't mind screwdrivers, clamps, and glue. 

Duke is pretty modest but if you read mine or Tim's (noble100) posts you'll get a feel for just how good these things are.
