@Eron. I just bought the SW-110b, my first Klipsch product ever. I am blown away by this sub, paid about $380 at a local Fry's Electronics Store. This sub is tight, punchy, and quick for music and also gets low at 28hz for LFE. I must admit I have only owned Polk subs before and they are toys compared to the SW-110. I have listened to a Velodyne Impact-10 and thought they were great as well, but for a comparable price I liked the SW-110 better. I think the woven fiberglass driver, the slot port, and the BASH amp give it just the right balance for HT and music. I have it paired with Polk Monitor 70 II mains and a pair of Polk TSi300 front wides and it blends in seamlessly. If you can afford SVS or higher end subs go for it, but I am loving my SW-110!
