Dave, I believe they're glued in, not just screwed in with battens like the old BF amps. So it is challenging, but can be done if you have the right tools.
If you're thinking about using a 15" speaker, this would also be a "one-purpose" mod, to reduce the weight. Tone-wise, you wouldn't gain anything by using a 15" speaker, and you'd probably lose a little perceived volume (due to the reduced radiating area). Put simply, this is one of the few amps where you don't have to rely on the speaker for the tone...it's in the amp!  [This message was edited by Donny Hinson on 27 April 2006 at 04:57 AM.] |

Dave, it would take some really specialized tools to get it out without chewing up the tolex. I sawed out the baffle of a Pro Reverb, and I chewed it up pretty bad in front. Also, a 15" in that combo cab will have a very tight fit because of the huge tranny. I'm not sure it's possible. If you are really set on keeping it in a combo cab, consider having Rick Johnson make you a new cab with a 15" baffle. You could have him add an inch or two to the height to be sure it all fits. That probably would improve the sound too.
But you know my feeling - I wouldn't want that 100 lb. anvil of a combo. My Super Twin Reverb in a Dual head cab weighs 50 lbs. - no big deal. And my heavy duty Eminence 15" speaker in a Vibrasonic cab converted to a closed-back reflex speaker cab weighs 48 lbs. I'd just much rather have the two packages. I like the flexibility of putting the amp beside me and being able to put the speaker some distance behind, maybe on a chair or stand.

Just speculating;
the STR I have has no speakers in it. I have an old Fender 2x12 60's era cabinet (Bassman) I could plug it into; I'm worried about the power handling- although i never expect it to get THAT loud.
Dave- is the "Dual head cab" a DSR and is it a swap-in fit for the STR chassis?

| Yep, the DSR, STR, Twin, Vibrasonic and Pro Reverb all fit in the same head cab. |

For the Twins with the fixed baffle, I have cut the baffle with a saber saw, leaving about a 1-1/2" lip all the way around the perimeter. Then, I made a 1/2" plywood baffle cut for the 15" speaker, installed T-nuts to secure the speaker and attached the new baffle from the rear. The "lip" had to be adjusted at the bottom so that I could mount the 15" speaker from the front (I prefer fron-loading the speaker although rear-loading would have been easier). I secured the new baffle to the lip with a bunch of drywall screws. The remaining "lip" still has the Velcro pads for the grille.

David S's approach might work for a ST. But attaching the new baffle to the back of the lip of the old one moves the speaker further back in the cab, further complicating the fit in the Super Twin. His approach of loading the speaker from the front and carving out some of the lip at the bottom apparently solves the problem for a Twin, and might also work for a Super Twin. You could also attach the new baffle to the front of the old lip. This will cause the grill to protruded a little, but might solve the fit problem even for a rear loaded speaker. Just be forewarned that the ST tranny hangs down further than in a regular Twin. There are certainly one or more ways to do this, but you have to plan and measure carefully.

I once bought an amp with the 212 baffle cut out and the extra 115 baffle installed.
It really didn't work well, buzzes, rattles and the 1/2 regular ply baffle is too weak for the 15 and the associated power.
I ended up peeling the tolex, knocking the cab apart, cleaing out the baffle dadoes, and installing an exact fit baffle.
Retolexing got me the added bonus of an amp that looked showroom new.
