JBL XPL90
The JBL XPL90 was a 2-way bass reflex bookshelf speaker that JBL introduced as part of the XPL series, which replaced the earlier TLX line. It paired a 200mm (8") polypropylene woofer with a 25mm (1") pure titanium dome tweeter, crossing over at 3kHz. The cabinet was finished in walnut veneer over MDF, and each speaker weighed 10kg. Specs are well corroborated across sources: frequency response was rated at 55Hz–22kHz ±3dB, nominal impedance 8 ohms, and recommended amplifier power 25–150W. Dimensions were 440×280×330mm (H×W×D). The original UK price was £419.95 per pair; in the US, Vintage JBL USA lists it at $550 each. Sensitivity is generally cited at 91dB (1W/1m), though one source lists 90dB.
Period coverage of the XPL90 is thin. Hi-Fi Answers reviewed it favorably and gave a technical assessment of the drivers and cabinet, which anchors much of what's documented today. A 1991 issue of HiFI-Stereo listed the larger XPL140 alongside other JBL speakers, including the JBL2800 bookshelf speaker with its 8-inch polymer-laminate woofer and 1/2-inch dome tweeter (HiFI-Stereo, 1991, p.167). Past that review, the record is mostly enthusiast reports. Owners on forums describe the XPL90 as a great speaker with excellent imaging, and a German dealer listing calls it one of the best-sounding bookshelf speakers of its era, rating it "very good." Exact production years aren't documented in any source we've found. Finish options beyond walnut, crossover components and common failure points haven't surfaced either.
