I have used the EV 15B ( 2 of them ) , for many years, in some homebuilt enclosures, I built those cabinets according to the EV design plans, they worked well, when using a Traynor YBA-3, and a Crate BT-350, really didn't have volume issues, but with today's amps, and the headroom available, you really need to be careful, as the chance of cooking those voice coils is very real, as a side note, a few years ago, I acquired an old Ampeg V4-B cabinet, had really no idea what was in it, the first run of that cabinet line usually had "Altec's" in it but I read, that the later years they were installing EV15L's in them, I pulled the grill off and the access panels, and low & behold ...a pair of EV15L's, they sound pretty good, I really don't gig this cabinet, as it's just too big, and the throw is pretty far, but one must remember, those old speakers were developed, when amps were 100-300 watts RMS
