Diapason Bass Module
We adapted the Shahinian Acoustics Obelisk unique hybrid transmission line bass chamber to a twin back-to-back configuration. The east / west driver position and rear-mounted passive radiators have many advantages and offer a modular flexibility. A single unit can be used with simple passive low-pass filters for a 3-unit satellite-type system, or as an add-on to existing full-range systems to augment the bass and reduce distortion.
Two units can be bridged to mono, yielding left and right channel dula woofers for even more power handling and lower distortion with a lower 3 dB cutoff. eg with the Diapason Module as in the 'Diapason Ensemble'.
Twin, back-to-back, hybrid transmisson line/passive radiator bass chamber with two 8" cone drivers, 3/4" Finland Birch cabinet construction; built in 140Hz / 280Hz 18dB passive filters which may be bypassed for bi-amp operation 5-way binding posts. Sits on 4 twin wheel casters
