I bought this speaker for my Reinau Tweed Deluxe, which is an hand made in Denmark 5e3 amplifier. The speaker sounded great and I used it in this amp for a while. I later replaced it with a Jensen P12R, so I moved the C12Q in a home made 5f1 champ. I really feel that this speaker suits those small tweed style amps, it really captures that vintage sound, very midrangy, with loose bass. It makes the natural overdrive from turning the amp up sound really full and yummy.
