JBL 4690
Documentation on the JBL 4690 is thin. What the record shows: it was part of JBL's Cinema Series — one of the company's larger speaker systems of the 1990s, as one owner on an audio heritage forum put it. The same forum thread confirms at least one enthusiast owned a pair ("I have two of them"), though no detailed sound commentary from that thread was captured.
The only concrete specifications that have surfaced come from a single source: an 8-ohm nominal impedance and a 600-watt power handling rating. Both figures appear on just one page, so treat them as unverified rather than settled fact. No frequency response, sensitivity, dimensions, weight, driver complement, crossover data, or original price has been documented anywhere in the available record.
Interestingly, JBL announced a pair of Professional Series speakers in late 1980 — the 4690 and 4695 Extended Range Playback Systems — described in Recording Engineer (December 1980, p.93) as compact two-way systems in 3/4-inch multi-laminate hardwood enclosures with black polyurethane paint. Whether JBL reused the number or the sources are conflating two distinct models is unclear from the record.
- Impedance: 8 ohms (single source)
- Power handling: 600 watts (single source)
- Series: Cinema Series (forum reference)
If you own a 4690 and have measurements, photos, or period literature, the archive would welcome the contribution — right now, this page is honest about how little is confirmed.
