Subwoofer with 2 channel stereo setup

I have main speakers that go into the 20 Hz region, but setting the crossover at 80 Hz, thereby freeing the mains of LF duty, makes the system sound even more transparent and open, and seems to expand the sound stage while maintaining precise imaging.

Sean,

I first noticed the improvement in transaparency, openness, and soundstage when I had been using KEF Reference 102/2s with a Velodyne HGS-10,; it seemed intuitive to limit the frequency range, given the small size of the 102/2s. When I substituted the much larger KEF Reference 104/2s, I decided to send the full frequency range to them. But when a Velodyne HGS-15 from a local source was delivered by an installer very familiar with high-end audio, he suggested I use Proceed's 80 Hz crossover even with the 104/2s. I was surprised to find the the same effect as with the smaller speakers.

The HGS-15 sits on an Auralex SubDude, and blends seamlessly with the KEFs. For movies and HDTV, surrounds are a pair of 102/2s with a KEF 200 C center speaker. The other pair of 102/2s and the HGS-10 have been moved to a secondary system, and provide good sound for the living room.
