Ok, so a quick rundown of my rig. I play 335 style semi-hollow body guitars into a Reeves Custom 50 into a Marshall 1960a cab. I play hard rock and get my overdrive and distortion from pedals. Overall I am very happy with my tone especially if I am playing a room where I can turn the amp up to get the speakers moving some air. I guess I don't always like the sound of the G12T-75s at lower volumes. I like them quite a bit at higher SPLs though so I was thinking of replacing two of the speakers in the cab and getting a nice mix. I would probably be looking for speakers that sound good at lower volumes, but also retain clarity at higher SPLs. I would also want something that is a little smoother (aka, less top end) than the G12T-75s. I was thinking of getting a pair of Weber Ceramic 1265. What do you think? What combinations have you guys found successful?
