the speaker level output terminals from any receiver,

amplifier or integrated amplifier to the inputs of the PS112 Powered Subwoofer.

The McIntosh PS112 Powered Subwoofer is designed for Home Theater and Music Reproduction. It has a 12 inch LD/HP1 woofer, a 400 watt amplifier and built-in high and low pass filters.

The PS112 Powered Subwoofer’s performance is equivalent to the quality of McIntosh’s legendary line of Amplifiers, Preamplifiers, Signal Processors, Signal Sources and Loudspeakers, without imparting distortion or coloration of its own. It also complements the capabilities and the remarkably low distortion of McIntosh Power Am- plifiers.

Many of today’s loudspeakers are designed only for Home Theater applications. Not so with the PS112. It is also designed for the accurate reproduction of the low fre- quencies contained in music. Motion picture sound effects, explosions, and vehicle crashes require a wide dynamic range and high sound levels. These sounds are such that a speaker system having moderate distortion would repro- duce them with little audible difference. This is not true with the reproduction of music. Music is by nature and definition harmonious. To reproduce it accurately, all forms of distortion, both harmonic and intermodulation, must be kept to a minimum. This has been the result of the design of the new McIntosh PS112 Powered Subwoofer. Each component in the device has been carefully designed for durability, efficiency, and above all, low distortion. The McIntosh PS112 Powered Subwoofer will reproduce music accurately and function as an excellent Home Theater Pow- ered Subwoofer.
