JBL Ti1000 (1993)
The JBL Ti1000 is a two-way, bass-reflex bookshelf speaker from JBL's Ti series, the company's "high-definition" home line of the early 1990s. It came out in 1993 at ¥160,000 per unit. It was the only model in the Ti series (which also included the larger Ti5000 and Ti3000) sold in Japan. It's compact but heavy at 18kg, and measures 265 x 450 x 235 mm.
The low end is handled by a newly developed 16.5 cm cone woofer, the 706H, whose pulp diaphragm is coated with JBL's proprietary Aqua Plus material for controlled internal loss. A powerful SFG magnetic circuit and a 37mm edgewise-wound voice coil drive the bass. High frequencies come from a 2.5 cm dome tweeter, the 050 ti, with a pure titanium diaphragm and what JBL called a "unique diamond edge." The crossover sits at 3kHz, impedance is 4Ω, and the rated frequency response is 50Hz–30kHz (-6dB), with an output of 89dB/2.83V/m. Allowable input is 75W program.
The enclosure is a bass-reflex design with a double-walled, isocore-laminated internal structure. The side panels use a slant-side style with no parallel surfaces, which reduces internal standing waves.
Surviving documentation on the Ti1000 is thin. Production is generally placed at 1992-97, and used examples occasionally surface in European markets. One German listing noted the speakers were "Made in Denmark," which suggests some production outside the U.S. There's also a small aftermarket following in Japan, where Kenrick Sound offers custom-tuned versions of the Ti1000, and comparison videos between original and modified pairs exist on YouTube. No detailed service information, common-failure notes, or comprehensive market-price data have surfaced in the available record.
