These subs are catching lows! They have a great range of sound and are producing tons of bass. My truck is slowly falling apart lol. They hit tremendously hard if powered right! Very similar to the sound of an L7 but a little more inexpensive. They have been the best subs i have had so far and I have 2 15" 4ohmDVC's powered by a Rockford Fosgate T1000-1bd wired at 1ohm. They are definitely satisfying my bass addiction. Very sturdy subs as well. They look awesome, sound great, and people WILL know you have a system...trust me. These things are beyond wangin'. Again i stress they HIT HARD! The best part is you not only hear the bass but FEEL it too. Great Subs. Def recommend.
