JBL TM930 (c. 1990)
The JBL TM930 is an elliptical 3-way automotive speaker. It's a 6×9 oval coaxial that JBL sold around 1990 for ¥70,000 per unit. It belonged to the TM Series. The T595 seems to be the most famous model in that line, and the TM930 isn't it, but it was considered fairly high-end in its day. One Japanese owner recalls it costing roughly ¥70,000 for the pair, and notes it was "quite high-class at the time."
The TM930 is a 4-ohm, 3-way coaxial with a 150×225mm aperture. The low range uses a polypropylene cone. The high range uses a pure titanium diaphragm. The magnet is JBL's low-distortion SFG circuit, with an edge-wise wound voice coil. Rated frequency response is 40 Hz to 22 kHz, allowable input is 120W, and output sound pressure level is 93 dB.
The record on this model is thin. There are no production years beyond "around 1990," no overall dimensions or weight, and no period reviews have surfaced. What does exist is mostly anecdotal: owners using them as rear fill in cars (one in a Peugeot 306), and a steady trickle of secondhand listings. Foam surround repair kits are still sold specifically for the TM930, so these are being kept alive rather than parted out. Recent auction activity on Yahoo! Japan shows pairs and singles hovering around ¥25,000, and a used pair listed on an Italian marketplace went for €100.
