The short answer is YES.
I recently picked one up for use in a near field application to round out the bottom end of a pair of the Pioneer BS41s. I figured that for the sale price I couldn't go too wrong. What stunned me was just how good it actually is. In my system, the BS41s perform FAR, FAR above what their price would suggest. Well, the SW-8 does a fine job of enhancing their low end while retaining all the positive aspects of tonality, dynamics and control which the BS41s exhibit. This is a purely 2 channel system (not really technically 2.1) and is EQ'd with a BFD. With the SW-8 I'm getting usable response down to 20Hz in my compact space, and while this is highly unlikely in a large or acoustically unfriendly space, it's still worth noting. Overall output is the same story. It has plenty of headroom for my application, I can't comment on its use in a larger space. I also have yet to hear any port turbulence, regardless of frequency, but we're talking about the 90dB range near field, so YMMV. Anyway, it's a bargain and I wouldn't hesitate to recommend it. My friend was over yesterday and commented on how impressed he was and he owns an Epik Empire, so it's doing some things very right.
