The MTS-4 is a fully integrated unit, containing all the drivers and amplifiers needed to handle both high frequencies and lower subharmonics. No extra subwoofers and no extra amplifiers are needed, and all of this comes in only seventeen cubic feet of cabinet!

Each of the three low frequency drivers has its own vented chamber, creating acoutstical addition that gives the MTS-4 its impressive output levels. Its high frequency horn rounds-out the audio spectrum to produce a wide, flat frequency response (±3dB from 30Hz to 16kHz).

The MTS-4 is easy to set up. The power supply utilizes the Intelligent AC system, which provides for automatic voltage selection, EMI filtering, soft current turn-on, surge suppression and dual circuit breakers. Simply plug in a power source and an audio signal.

The power system utilizes a dual fan, forced air cooling system which removes the heat from the heatsink and exhausts it to the rear. Since air is not directed over the electronics themselves, dirt cannot accumulate on sensitive components -- increasing the reliablility of the amplifiers.

The MTS-4 is as impressive to listen to as it is easy to install, with phase corrected drivers, balanced input circuitry and constant time response.

Servicing of the MTS-4 is facilitated by a rear access panel; the entire power/amplifier module can be removed and replaced.
