Electro voice Sp12b 12 inch speaker

Up for sale is a classic Electro-Voice Model SP12B 12-inch full-range (Radax coaxial) loudspeaker. This is the real deal from EV’s golden era of American hi-fi and pro audio

The SP12B was a workhorse driver known for its smooth, balanced sound with solid bass extension and clear highs thanks to the integrated whizzer cone design. Frequency response is roughly 35–45 Hz to 15 kHz, with a mechanical crossover around 4.5 kHz. It was used in many vintage EV enclosures (like the Aristocrat or TRXB systems) and was respected for its efficiency and musicality. Collectors and restorers love these for their durability and that unmistakable vintage EV tone.

Condition notes (see photos):

•  The magnet and frame look solid with the expected patina and dust from age.

•  The cone and surround show some typical wear and surface marks consistent with a speaker of this vintage.

•  The whizzer cone is intact.

•  No major rips or holes visible.

•  Original label is clear: “Electro-Voice Inc., Buchanan, Michigan – Model SP12B”.

This driver is perfect for a restoration project, a custom cabinet build, or as a replacement/upgrade in a vintage system. It could also shine in a guitar amp or monitor setup if you’re after that classic American sound.
