Query: Can't beat this quality for the price

Polk is an industry leader in audio products, and this sub-woofer definitely falls in line with that. For only $100 this woofer adds such great depth to my surround sound system (Onkyo Tx-NR616 receiver + Pioneer Sp-FS52-LR tower speakers, Pioneer SP-C22 center, and Pioneer SP-BS22 Bookshelves).First impressions:*Great tight bass for music*Solid low end boom when watching movies*Great for a variety of music- played some Rap and dubstep and hit HARD, then played some Shins and Ben Folds and sounded so clear and tight (without heavy bass echo)Concerns:*Would be great if it had an LFE input*I used a y-cable to connected my LFE output to the two RCA input jacksI would HIGHLY recommend this to other users!
