JBL 2110H (1980)
The JBL 2110H is a 200 mm (8 in) extended range transducer, released in 1980. It's a shallow-cone driver with a paper diaphragm and an aluminum center dome. JBL used that combination to improve high-frequency behavior while keeping the overall depth low. The driver measures just 7.9 cm deep and weighs 1.9 kg. It was rated at 8 ohms, with a 50W continuous program input, 96 dB/W/m sensitivity, and a published playback band of 60 Hz to 10 kHz (fo 60 Hz). Magnetic flux density was 8,500 gauss. JBL suggested enclosure volumes of 56 to 85 liters.
Not much is known about how it was used. The spec sheet says it could serve in a line array PA context or as a standalone wide-band unit. A French forum user reported owning four of them - two new, two needing replacement diaphragms. A recone kit is available from aftermarket supplier QSR (priced at $88.00 AUD), which confirms the voice coil is a flat-wire 8-ohm unit with a 2.006″/50.95mm ID. The 2110H also appears in the Kemper Kabinet's list of speaker "imprints," so it's modeled as one of the virtual cabinet options on that digital amp platform.
Beyond the 1980 brochure listing, documentation is sparse. There's no production end year. There's no original retail price for the driver itself, though a 1981 Japanese price list shows ¥28,000, the only period number. There's no confirmed list of which JBL speaker cabinets, if any, shipped with the 2110H as standard equipment. The cone is an 8″ unit with a 1.4″ depth and a 1.0″ voice coil opening, per The Speaker Exchange. No period reviews turned up in the major hi-fi magazines.
