Plus, I'm thinking that if you are in the market for buying a new sub and you are wavering on the decision that a DSP controlled sub is worth the extra price, you could save a few hundred by buying the non-DPS version (350 anyone) and then put the money towards this item that does both the EQ function and adds DSP control.

Great, now I really, really want to buy stuff.

With great power comes Awesome irresponsibility.
