Acoustic Research M6
Little is documented about the Acoustic Research M6. What the record shows comes from a single period review in Audio (January 1992, p.70). It indicates the M6 was a two-way bookshelf speaker using the acoustic-suspension principle AR had pioneered decades earlier.
The M6 paired a 6-inch cone woofer with a ¾-inch soft-dome tweeter, crossing over at 3.6 kHz. The acoustic-suspension enclosure was covered in charcoal-gray vinyl wrap, a plain finish that kept costs down. Sensitivity was rated at 88 dB for 2.83 V at one meter. Nominal impedance was 8 ohms (5 ohms minimum). The recommended amplifier power of 10 to 100 watts per channel suggests it was meant for typical receivers of the early 1990s rather than high-current separates. Dimensions were compact: 10⅝ inches high, 7¾ inches wide, and 11¼ inches deep.
