Looking for something really low efficiency (96db and preferably less) with rolled off treble for an ac4tv head and home use. Right now the cab has a 10" Veteran and a C12r. Sounds parkly, jangly etc not bad, actually quite exciting. But only with tone is all the way down so a little more tonal flexibility (lower mids and body) would be appreciated (different guitars, moods etc...). Am I stuck with a greenback? How does the 10" GB compare to a 12? Much less bass? I am looking at the Jensen P10r-f. Theoretically, this should work although some people may argue American voiced in Vox amps etc...what do you think? Other speaker options (other than EQ pedal)? THX!
