I was experimenting with some different speakers and decided to try the Jensen Neodymium 12" speaker in my '81, 60w Mk IIB. First of all the amp is nearly as loud as it was with the EV12L but weighs about 16 lbs less! I really like the EV12L but this Jensen sounds really good. It has a nice character to it. The clean sounds are warm and detailed with tight bottom and the Lead sound has a nice vintage sound to it also being warm with tight bottom. I was surprised with the results. I think I am going to try a second one in my 1x12 open back extension cab with it. Anyone using the Jensen neo 12"?
