Hi Travis,
I haven't tried the unit but it looks promising, and the price is quite attactive.
One of the benefits of a multisub system, like the Swarm, is a significant reduction in spatial variance - that is, the frequency response doesn't change as much from one location to another. This makes equalization effective over a considerably broader area. In the past at times I've had to argue "multisubs vs DSP", but the DSPeaker unit takes DSP into the realm where I can change my tune to "multisubs + DSP".
