JBL D130A (1955–1966)
The D130A is the 16-ohm version of JBL's legendary D130 12-inch driver, produced from 1955 to 1966. It was part of JBL's D-Series professional drivers, which also included the 8-ohm D130F (the version widely used in Fender amplifiers) and the 4-ohm D131. The D130A was aimed at hi-fi and replacement use rather than the guitar-amp market that the D130F dominated.
The driver is known for its distinctive white painted cone with a curvilinear profile, a large Alnico V magnet, and an edge-wound aluminum voice coil. Rated at 50 watts program power with a frequency response of 50–9,000 Hz and 94 dB efficiency (1W/1m), it was a high-efficiency, rugged design that earned praise for its clean, articulate sound and ability to handle high volume levels without distortion. The shallow frame made it suitable for open-back cabinets, where enthusiasts report the bass stays tight and the driver "can breathe." Audio (February 1957, p.41) ran JBL's own advertising for the D130, positioning it as "your basic speaker" — the finest 15-inch extended range speaker made at the time, to be paired with a JBL "Harkness" enclosure and 175DLH high-frequency assembly.
Original price was $70.50 in 1959. The D130A was offered with push terminals and was made in the USA.

Collector notes from the AudioKarma forums indicate the D130A is a favorite for pedal steel and country guitar — described as "clean and sterile" rather than a rock speaker, with some users noting it can sound bright and edgy by modern standards. Common issues include foam rot, voice coil rub, and cone cracking. Original-cone examples command roughly double the price of reconed units, with typical eBay prices ranging from $250 to $450 depending on condition. Recone kits exist from third-party sources, but enthusiasts caution that new cones don't match original JBL specifications.
Surviving documentation on the D130A specifically is thinner than for the D130 platform as a whole. No Thiele-Small parameters, cabinet volume recommendations, or crossover specifications have surfaced in the sources available to the Archive. If you have original JBL literature covering the D130A, the Archive would welcome the details.
