The Paradigm subwoofer range is extensive, but this their flagship model; the Signature Sub 2 is about as goood as it gets!
The Home Cinema Choice review by Adam Rayner states “Absurdly monstous and profound in output”, “The biggest baddest subwoofer from the top range of a very high end speaker maker”.
The Signature Sub 2 “has limitless power, huge speed , awesome control and is beautifully engineered”. 4500w RMS, six 10″ drivers and will pumb the subsonics level of 7Hz!!

Kent Home Cinema loves this subwoofer!
