The Image Subsonic 6 delivered a tight and punchy sound, with tremendous dynamic wallop. Most subs of this price sound slow, smeared, and boomy, characteristics that are a constant reminder you are listening to a subwoofer. The Image 6 was articulate enough to integrate well with the 6T left and right speakers, yet powerful enough to be used just for reproducing the Low Frequency Effects (LFE) channel on myany DVDs. (The LFE channel is the .1 channel in 5.1-channel sound.)
