I'm running a Denon 3802 with JBL S26s and an S-center. I'm looking for a sub to complete the system, and the velo spl-800 caught my eye. This will be the first subwoofer I've purchased, and I'm a bit concerned. The woofers in the S26s are 6 inches, and they don't output that much bass. Of course, they're bookshelves, and aren't meant for that... but does an 8 inch sub really put out that much more? I'm actually looking for accurate, 'tight' Bass, but I'm concerned about the volume level too. Of course, I've yet to listen to any of the subs I'm looking at (probably going this weekend or so), but I'm curious about this, and any input is appreciated.
