I'm building a new speaker system for my computer. After being disappointed with Logitech's Z-680s for their hissing and awfully boomy bass, I decided to go with a receiver and "real" speakers. The receiver will be a Denon 1403 and the speakers will either be some refurbed Infinity Entra Point 5's or Entra Ones. I really don't want to spend more than $150 or so on the sub. I basically want something to fill in where the sats leave off (especially if I go with the point 5 set). I cannot stand boomy bass, but I have nowhere to put the sub other than under my corner desk. Size is important here. Under 13 inches tall if I can help it! I've seen people talk about the AR PR808 and the Dayton sub from PartsExpress. I heard a Velodyne CHT8 at Circuit City and liked it, but it was $300. Is the Velodyne VX10 for $150 in a different league or could I expect similar performance? I think an 8 inch sub would probably serve my needs fine since I'm not a bass head and I'm on a budget. 90% of my music is pop, rock, electronic and blues. All input welcome. Wow, the Dayton sub is on sale for $99 today and tomorrow... this is awfully tempting.
