Been a while since my last post on here. But I'm getting ready to start building me a blackface deluxe reverb clone and I'm having trouble deciding on a speaker. My previous amp was a Super Reverb with the giant JBL 10's. Up until yesterday I had decided on a 12" speaker instead of a 15", so I started shopping for 12's. I had it narrowed down between a Weber 12A125A (30 W, $108) and their 12A150 (25 W, $208). But reading forums and reviews scared me away from the 12A125A because everyone was hating on it for lacking the bass of the 12A150 (bigger magnet, bigger voice coil) so now i'm thinking about building a slightly taller cabinet and put in a 15A125A (15", 30 W, almost identical to 12A125A but 15", $123) so I can make up for the bass as well as get a totally unique tone (AB763 into 6v6's into a 15"). I'd rather not pay $208 for a speaker. Basically what I'm asking is would there be a considerable difference in bass with two identical speakers except for one being a 12 and the other a 15? and also if anybody has any other suggestions on a good alnico for a deluxe reverb?
