Alpha3, I noticed the little rubber feet are too short and the sub sits too low to the floor. I had Hifi Pyon custom make a sub platform($600shipped) for it with resonance isolation feet under platform and under sub. Wow what a difference it made. I have never heard better bass, controlled, defined, and really tuned the pitch of the bass. It was well worth the money and it is still way lower in price than a JL Audio F113...:)
