JBL XTi10C (2000–2002)
The JBL XTi10C is a center-channel speaker from JBL's XTi series, produced from roughly 2000 to 2002. In Japan it sold for about ¥45,000 per unit. The "C" stands for center. It was designed to sit horizontally beneath a screen, and it has magnetic shielding to protect nearby CRT televisions.
It's a 2-way, 3-driver bass-reflex design. Two 12.5 cm pulp-cone woofers with corrugated rib surrounds flank a 2.5 cm pure-titanium dome tweeter with an aluminum voice coil. The crossover sits at 3.5 kHz, rated impedance is 6 ohms, and it handles 50W RMS. Frequency response is stated as 60 Hz to 35 kHz, with a sensitivity of 89 dB/2.83V/m. It measures 510 × 197 × 258 mm and weighs 7.0 kg.
The enclosure is the interesting part. JBL built it as a hexagonal cabinet - four main panels (top, bottom, front, and rear), with the front and sides integrated. There are no parallel surfaces, which reduces internal standing waves. The construction is eight-piece solid MDF with no parallel side panels, and JBL claimed this gave a rigid, resonance-free structure. The woofer's magnetic circuit uses a bent pole piece to suppress dynamic compression. Terminals are gold-plated binding posts that accept banana plugs, and the speaker supports bi-wiring or bi-amplification. A matching stand was offered as an option.
Documentation on this model is thin. The XTi series also included the XTi20, XTi60, XTi80, XTi100, and XTi SUB300, but little period press coverage of the XTi10C itself has survived. One source notes that XTi series loudspeakers "may differ in some respects from the published specifications and descriptions, but will always equal or exceed the original specifications unless otherwise stated" (ManualsLib). Foam surround repair kits are available for the XTi10C today, which suggests the original surrounds age the way most foam surrounds from this era do.
