I have a tweed clone amp, 1x12", that I absolutely love! 50 watts with five 12AX7 tubes and four EL84 matched output tubes It has a basic stock (no name-8ohm) speaker and although I can live with the sound, I thought it might benefit from a speaker upgrade. The cleans can get a bit bright and thin. Is there a speaker that I can add that will smooth out the cleans and also lower the perceived volume...this thing is loud! It also has cab outputs in 4,8,and 16 ohm varieties so I could just add a cab with another speaker to get my wishes? Thanks!
