JBL MR822
The JBL MR822 is a two-way loudspeaker system from JBL, and the record on it is thin. The available documentation shows a compact design with a 20 cm (8-inch) cone woofer and a 2.5 cm (1-inch) dome tweeter, crossed over at 2500 Hz. It was rated at 90 dB sensitivity with a nominal 8-ohm impedance. Maximum input power was 200 watts.
There are minor disagreements between sources on two specs: frequency response is listed as either 35 Hz–22 kHz or 45 Hz–22 kHz depending on the reference, and weight as either 9.5 kg or 8.7 kg. Both figures appear in period equipment databases without a clear primary source to settle which is correct. The cabinet measures 400 mm high by 260 mm wide by 320 mm deep.
A service manual exists for the MR822, which suggests it saw professional use where maintenance documentation was expected. Beyond that, almost nothing is recorded about its design philosophy, market positioning, or reception. It appears to have been a workaday pro speaker rather than a flagship - the sort of box you'd find in a small venue or installed system. A single used sale was recorded at just under $350. The model was advertised in period music retailer promotions, including a November 1996 issue of Sound on Sound, p.205.
