Honestly, unless anyone as heard it, we wont be able to say. That said Ive seen one very good review of it from a person I trust and the results were stated as nothing short of excellent. Really, all eq should integrate the sub seamlessly, and your sub will no doubt be better with it than without, so even if its not perfect it should still be preferable. From what Ive read though, its at least on a par with the EQ-1, with Paradigms subs at least. On that alone I would expect it to be very good.
