Paradigm doesn't move models in and out of its Reference Signature lineup very often, and the SUB 25 was introduced less than a year ago. Progress never stops, though, and the SUB 25 has been displaced as top dog by the SUB 2 and its "little" brother SUB 1. These new designs feature six drivers (10-inches in the SUB 2, 8-inches for the SUB 1) arranged in three radially symmetric stacked pairs -- the end result being a lot of effective radiating area with in-cabinet forces that balance each other out. In the real world, that means more boom and less buzz, especially with the kilowatt range Class D amps Paradigm includes in these subs.

The €3,500 + vat price tag on the SUB 1 is comparable to the outgoing SUB 25, while the SUB 2 will cost you  €7,500 + vat. Not cheap but if you want the very best subwoofers on the planet then these are the subwoofers for you.
