What would be the best choice

A friend has two Vandrstein subs with his 804's, they sound seemless together
If you can find a used B&W ASW-800 it will be a perfect match. The ASW-800 is the Matrix sub. For a REL, I would consider the Storm III at a minimum.
two martin logan original dynamos sealed box fast and very musical sounds awesome with my 805 matrix imho
Has anyone used a Velodyne sub with the B&W Matrix 805s? If so what model #s?
A friend of mine used a Velodyne sub with B&W Matrix 805s a long time ago. It was the ULD-15 I think. Amplification was Krell. Awesome sound. He still regrets selling that system.
