JBL Project K2 S9500
Documentation on the JBL Project K2 S9500 is thin. What exists comes mostly from classified ads and forum posts, not period reviews or official literature. The S9500 was part of JBL's K2 Sx500 range, a family of four models, and sat at the top of that line. It is a large floorstanding loudspeaker with two woofers flanking a high-frequency horn. The design team is credited to Greg Timbers (crossover, horn, and enclosure), with Doug Button on bass development and Francher Murray on the high-frequency driver.
What the record does show is a seriously capable speaker. The S9500 pairs two 15-inch (380mm) Aquaplas-coated pulp cone woofers with a 4-inch Aquaplas-coated midrange, a horn-loaded titanium tweeter, and a 0.75-inch pure titanium compression super-tweeter. Crossover points are set at 250Hz, 2.2kHz, and 15kHz. Sensitivity is rated at a very healthy 98dB, nominal impedance is 8 ohms, and allowable input is 300W. Frequency response is quoted at 38Hz–50kHz (-6dB). The cabinets are substantial — 1362 x 548 x 489mm — and at 199kg each, these are not speakers you move casually. The woofers use fiberglass/aquaplas cones, and the suspension on the woofers is known to need replacement over time; at least one owner has had theirs rebuilt professionally.
Owners who have written about the S9500 are enthusiastic. One Russian-language forum user described them as "very impressive speakers with gorgeous sound - even, detailed and agile, with a wonderful soundstage," while noting the price tag is a stopper for most. A Korean classified listing described a mint-condition pair at ₩10,000,000. A pair sold through a Japanese dealer in June 2017 for ¥1,100,000. That unit had some grille dowel damage and minor cosmetic wear, but the seller confirmed it played with good sound. Another used pair was listed in Australia at AUD $12,950. There is also active demand for replacement woofers.
No production years, original launch price, or official design documentation have surfaced. A StereoNET listing called the S9500 "legendary" and "a must-have for the enthusiast or collector."
