M&K Miller & Kreisel The Volkswoofer Internally Amplifier Subwoofer - $175 (St Marys)

1234567
Miller & Kreisel were at the forefront of many technological breakthroughs in audio history. Headquartered in Hollywood, CA., they built professional screening rooms for directors, producers, actors, and the Hollywood elite. These facilities were used for both work and pleasure and M&K was pioneering home theater technology years before any other company. Their goal was to take the technology and knowledge they gained from building professional studios and theatres, and create a commercial type of theater environment in the home. M&K developed the world's first subwoofer when they designed the studio monitoring system for Steely Dan's recording studio in 1973. In 1977 M&K designed and produced the world’s first Self-Powered Subwoofer, The Volkswoofer. This idea revolutionized the entire audio industry. The internally amplified Volkswoofer is different than most subwoofers I have experienced. While most subwoofers are geared to home theater and are found lacking when it comes to music reproduction, The Volkswoofer shines in a musical application. The original Volkswoofer 12" Discover Deep Bass woofer was just recently refoamed with the correct rebuild kit from Simply Speakers.It has line level and high level inputs, an independent crossover on the amp, gain control, as well as a three setting Room Matching Control feature. The three settings are labeled Calibration Response, Room Variation A, and Room Variation B. The description for the three settings are as follows:

1. Variation A is the recommended setting for most rooms. This reduces only the lowest octave of bass (below 30 Hz) and greatly helps reduce low frequency standing wave problems, along with turntable feedback and modulation noise. It is especially effective in listening rooms with wooden floors. In most rooms, this yields the flattest overall bass, particularly in the most useful range, 40 to 100 Hz.

2. Variation B gives a more "punchy" mid-bass response particularly suited to contemporary electronic rock or disco music while further reducing turntable feedback problems associated with the last octave of music (16 Hz - 32 Hz).

3. The calibrated position is set for the flattest response in an anechoic chamber (18 Hz - 100 Hz +/- 3dB). In most rooms, however, this position will not yield optimally flat bass. It is recommended only for the reproduction of frequencies below 30 Hz (organ pedal or synthesizer bass) at moderate levels, when used with a stable, isolated turntable setup.

The cabinet is in good cosmetic condition with minimal scratches and blemishes. The original grill and grill cloth are in nice condition with all grill posts present and the M&K badge intact.
