Thank you for viewing. This item is a Jensen ceramic magnet speaker. I previously acquired this as a beautiful used item. I once installed it in a Tweed Tone 5E3 Deluxe type tube amplifier, but I felt that an Alnico speaker suited it better, so I removed it immediately. It is in a beautiful condition with almost no signs of use. How about it for a Fender Deluxe Reverb or Twin Reverb? I think it would also suit Blues Deluxe, Hot Rod Deluxe, and Blues Junior. The Jensen C12K is also installed in the Deluxe Reverb reissue, etc., but I personally think that the 100W power handling is too high, and the bass is too boomy, which doesn't suit the amplifier. This one has a slightly lower specification, with moderate power and bass, and is recommended.

Please understand that this is a used item before purchasing.
