REL Brittania B2 subwoofer

A forward-firing subwoofer with 300 watt amplifier inside, the B2 transformed a number of systems ranging from an SET-based tube system with high-efficiency speakers to a more traditional high-powered solid-state ensemble with low-efficiency Apogees. This sub reveals a large amount of bass detail, not just bass depth, and provides a huge amount of fun as long as you’re willing to experiment with placement.
