The subs built into the BP7001SCs aren't going to be the exact same as a stand alone Supercube 1. With the stand alone you will be able to place the sub better for more optimum bass response, but even still it will not be anywhere close to the SVS. Remember, the Supercube 1 is a 10" sub, and the SVS is a 12", both are long throw subs, but the larger driver in the SVS will yield more displacement.
