JBL XTi20 (c. 2000–2001)
The JBL XTi20 is a compact bookshelf speaker from the Danish-built XTi Series, produced around 2000 - 2001. It's remembered mainly for the cabinet. It's a hexagonal, bass-reflex enclosure with a one-piece structure that joins the front and side panels, which minimizes internal standing waves. The design is 2-way, 2-speaker. The woofer is 16.5 cm with a pulp cone, a corrugation rib and a bent pole piece to suppress dynamic compression. The tweeter is a 2.5 cm dome with a pure titanium diaphragm and an aluminum voice coil. The cabinet is rear-ported and supports bi-wiring and bi-amplifier connections through gold-plated binding posts that accept banana plugs.
Specifications from the manufacturer's database: frequency response of 60 Hz to 22 kHz, 87 dB/2.83V/m sensitivity, 6 Ω impedance, 50W (RMS) allowable input, and a 3 kHz crossover. Dimensions are 227 × 382 × 300 mm (W×H×D), and it weighs 7.0 kg. It was priced at ¥85,000 per pair in Japan. An optional dedicated stand (XTi20Stand) was sold separately for ¥32,000.
Listening impressions from owners are consistently positive. A Russian-language listener on StereoNET noted, "I've always been surprised at how good they sound for this level of equipment." hifi-review.com praised its handling of the melodic quality of bass lines and noted solid power reserve. A Russian-language listener on archive.stereo.ru observed that raising the volume shifts the tonal balance toward the highs. The XTi series earned several listener awards in S&V magazine for its larger siblings (XTi 60, XTi 100).
The main practical issue for collectors today is foam surround rot. It's a common failure for speakers of this era, and re-foam kits are available. A service manual exists (2 pages, PDF). Current used-market pricing from Russian listings sits around 21,000 - 22,000 rubles, with condition ranging from excellent (original boxes) to units with minor cosmetic chips. Production period is documented as 2000-01. No THD or crossover component details have surfaced.
