I recently upgraded my audio system to a home theater. I am using my B&W 801's for the front speakers, set to large. Since these babies can pump out deep bass, I asked my dealer if I really needed to get a subwoofer. He most emphatically said yes, saying something about music vs. sound effects, etc. Trusting his judgment (I've been a steady customer for years), I bought the Velodyne HGS-12 he recommended. I set up the sub along the back wall of my room, forming a "sub triangle" with the 801's. Now, the test... I popped my "Godzilla 2000" DVD into the player and fast-forwarded to the first "foot stomping" scene and, sure enough, the whole room shook with each step. I was immersed in bass. The thing I noticed, though, was that the 801's held their own against the Velodyne. They seemed to capture every deep note. This got me to thinking that my dealer may have pulled a fast one, suckering me into buying something I didn't really need. There is plenty of bass with the sub turned off, although it emanates from the front of the room, not all around. Did my dealer sucker me, or is there a valid reason to use the sub? Is a sub always necessary, even with large front speakers?
