I havent heard it but its Freq response is 38-120Hz. There are better subs out there for the money. If you want a small sub from velodyne, consider the Minivee instead, 28-120Hz. These are very musical subs and quote-fast subs due to their non-ported designs. The minivee is basically an 8" SPL sub without the equilizer and remote control.
I'd rather go with the Martin Logan Dynamo over the minivee. Its also a sealed 10"sub and very musical.
