EXCELLENT CONDITION. One year old located in home equipment clean room. 350 Watts into 4 ohms. During that year I have designed and built my own sub-woofer amp so it is time to sell this one. Included is an expensive speaker cable ($700 new). Heavy duty power cable; owners manual; new strong shipping box.
The Stealth Acoustics 255R is an integrated monaural sub-woofer amplifier/crossover system designed as a low distortion power source. The 255R may stack with other components or mount in a standard 19” equipment rack requiring only two RU spaces (3-1/2”). The 255R delivers a solid 250 watts into an 8ohm load and 350 watts into 4ohms. A variable low pass, 18db per octave filter allows for infinite crossover points from 50Hz to 100Hz.
With a full complement of input and output connectors, the 255R is easily integrated into any audio system. Inputs include RCA line level, balanced XLR line level, and 5-way binding post speaker level, all with pass-through capability. The speaker level input/pass-through connections allow the 255R to feed directly from full-range speaker lines, anywhere in the system. The 255R’s amplifier output connection is via a 5-way binding post designed to accept heavy gauge speaker wires. A selectable automatic turn-on feature activates the amplifier only when audio signals are present.
Other features include an internal, quiet, 8-stage cooling fan that automatically engages as required. Front panel controls include volume control, variable low pass filter, low pass filter on/off switch, phase control, power switch and six power output monitor LED’s.
