In general, I'd stick away from the audiobahn. When I was looking they seemed to be SPL focused.

With some of their subwoofer models, this is true. But they make at least 10 different types. I highly doubt that every one of that many different kinds of subs are designed only for SPL. In fact, the model he listed seems to be from a series focused on clarity. I would not discount Audiobahn so quickly. And, it's quite easy to find their stuff for less than retail.
