Towering Tech Innovation is the secret sauce! A next-level top-plate design, unique heat management system and our signature cone stitching all help to give you deep bass and outstanding reliability in a single, mind-blowing design that gives you max output! DVC = OMG! Loaded with nickel-plated terminals, the L7T features standard dual-voice-coil design, so you always get the most out of your amp. Forced-Air Cooling As the woofer's cone moves downward, hot air around the voice coil is forced out of the woofer. As the woofer's cone moves upward, cool outside air is drawn into the woofer cooling the voice coil.
