JBL S76

The JBL S76 is a compact two-way bookshelf loudspeaker from JBL's vintage era. The record on it is thin. No production years, original pricing, or critical reception have surfaced. The spec sheets agree on this much: it's an 8-ohm, acoustic-suspension design with a crossover at 1,200 Hz, rated for 25 watts, and covering 45 Hz to 15 kHz.

The driver complement is a single 8-inch woofer and a 3-inch tweeter. The cabinet measures 19" W x 11.5" H x 9.5" D, weighs 21 lbs., and came in a walnut finish with a removable grille. Two independent vintage-spec sources list nearly identical figures, which suggests they draw from the same underlying data. That also means there's no second opinion on how the S76 actually sounded.

Beyond its listing in period equipment directories, almost nothing is recorded about the S76. A 1989 issue of Sound and Communication (Nov 1989, p.65) mentions JBL Professional in passing, but only in a job posting for an applications engineer. It has no review of the S76 itself.
