I have an old (late ‘60’s/ early 70’s) B15 cabinet (no amp on the fliptop...) that I plan to use with some of my smaller amp heads, such as a BT25 and maybe a B25B (if I can find one cheap). Basically going to run 50 to 100 watts into it. I’m looking at Eminence speakers and the Legend CA 154. I am definitely putting a 4 ohm in as the BT25 runs at 112(?) watts at 4 ohms, and I may occasionally plug in one of the old SVT’s into it as well, so 4 ohms for sure. I will be keeping my eye out for a B15N that would go with this cabinet, but I imaging that will be hard to find... Anyone have any thoughts on this? Also, does the early 70’s B25B head have a selector to run at 4ohms? I have a mid 70’s B25B 2x15 cabinet that has a 4 or 16 ohm switch, so I would think that the B25B head has a 4 ohm option.
