Thank you for looking. This is a [Jensen] Alnico PM12H vintage amplifier speaker. It was manufactured in 1947, has been reconed, and is in good condition. It supports 8Ω. I was told by the previous owner that it is the predecessor to the current P12Q. I used it connected to a Fender 8Ω amplifier, and it worked without any problems, producing a dry, flavorful, and very good sound. You can enjoy high-quality alnico sound with various amplifiers. I am also listing this item elsewhere, so I apologize in advance if it is sold out and I have to cancel. I am also listing many other effectors, so please take a look if you'd like.
