Features and Specifications

Owner's Manual

For uncompromising but architecturally difficult applications where our twin driver subwoofers just won't do, Sunfire's True Subwoofer Architectural Signature absolutely will. This design uses much of the technology found in the True Subwoofer MKIV and Signature, yet fits well into custom cabinetry with its single front-firing driver and removable cloth grill cover.

The True Subwooer Architectural Signature uses a built-in 1500-watt amplifier that incorporates Bob Carver’s Tracking Downconverter power supply technology and can fill even the largest rooms with tremendous bass extended to an unbelievably low 18 Hz.
