Pair of 12-inch, 12 Ohm - 35 watt guitar speakers made by Altec in Oklahoma City, OK in the 1960s. Yes, it is 12 ohm which means you can use individual speakers with an 8 or 16 ohm output. If both speakers are wired in parallel it will provide a 6 Ohm load which will work with a 4 Ohm or 8 Ohm output.

Really good sounding, highly detailed speakers.

• 12-inch ceramic magnet
• Stamped steel frame
• Rated at 35 W RMS
• Full-range voicing with extended upper midrange response with a paper dust cap, designed for guitar clarity rather than deep bass.
• Bright and efficient — often compared to an Altec 417 but less powerful.
• Strong upper mids and smooth breakup when pushed.
• Works very well in 1×12 combos like vintage Vox or Fender circuits around 15–35 W.
• Slightly stiff cone, so it stays clean at moderate volumes before breakup.

Voice coil: 1.5–2″ copper
Sensitivity: ~98 dB SPL (est.)
Frequency response: ~70 Hz – 7 kHz
Weight: ~9–10 lbs

I will consider selling only one for $125.
