About the True II
The Sunfire True Subwoofer Mark II is a compact, sealed-cube powered subwoofer designed by Bob Carver. Its approximately 11-inch cube enclosure uses opposing 8-inch long-throw elements in a passive-radiator configuration and incorporates a 2,700-watt Tracking Downconverter amplifier. Sunfire specifies frequency response from approximately 18 Hz to 100 Hz, with the exact tolerance varying by documentation. The continuously variable crossover covers roughly 35–100 Hz, with a steep 36 dB-per-octave slope, and the phase control is adjustable from 0° to 180°. Connections include line-level RCA and speaker-level inputs, while a fixed 70 Hz, 6 dB-per-octave high-pass line-level output can feed satellite speakers. The subwoofer uses optical input coupling, a black lacquer finish, and weighs approximately 43–48 pounds depending on the cited specification. It was discontinued and is no longer manufactured.
