Query: Excellent Sounding Sub

This subwoofer sounds great, i am currently running it with energy rc micro 5.1 system and it sounds great. The rc micro system came with an 8 inch sub that sounded great but just wasn't quite loud enough for me. So i upgraded to this, was a little worried about the sound quality but after reading many reviews and doing my homework i decided to go with it. I was not disappointed let me assure you, this thing pounds and at the same time produces great sounding bass. I recommend using a good quality subwoofer cable with this, preferably acoustic research, picked one of these cables up on ebay for 14 bucks shipped. Also make sure to use the yellow line unfiltered port on the back if you have a newer receiver with a subwoofer out on it. And dont be afraid to move this sub around the room alot until you find the perfect spot that sounds best with it.
