I don't think I got audio/video of the 12" alnico before I blew them, but the 15's are louder and I only have them on the baffle here:
Yes, my coordination is coming back...slowly, but I'm keeping a positive attitude and I'm going to get back on the proverbial horse. ;D
Just curious; does anybody have a Bassman or Showman cab, and does it sound better with the middle brace/2 chambers or without/1 shared chamber? How about open-backed? I aready glued the brace in, but I can knock it out if I need to.
Nice build so far, lefty! Good to hear from you and that you are coming back.
No info or experience with bracing in a Bassman or Showman cab. But I'm loving the 1X15 cab I completed last year, and I'm contemplating a second one for a stack. So your 2 15 inchers are intriguing me . . .
Most owners that have the braced cabs love them, because they tend to keep the cabinent quiet.
Be aware that the brace is not intended to stifle the standing waves inside of the cab - that's the job of the insulation that Fender installed, before the cab went out the door. The brace itself covered only about ¾ of the height, the top and bottom were open between the two speakers. The brace's actual job was to prevent the back of the cab from rattling at high volume levels, and to help keep it from caving in during bad cases of "roadie rash"..... you know, where the roadie has been partaking of the Golden Nectar a little too freely, and accidentally dumps your cab out of the "band van" and down onto the amplifier head already sitting just below the bumper. (Actually, it works both ways (clever of Leo, that) - the back reinforces the baffle, should the impact strike the front instead.)
If your cab doesn't have between 3 and 4" (depth) of insulation, do yourself a favor and put it in. (I used batts of R11, which is 3½" thick.) You'll find the lower frequencies no longer boom and/or get muddy, they stay tight and controlled at all volume levels. That's called 'damping', and most guitarists don't pay enough attention to that particular detail. (Bass players, on the the other hand.....)

Thank you sirs - your feedback, advice, and criticism are always appreciated!
Darnit, I totally forgot the insulation. The 2x12" is an open back with 2/3 panels. I don't know why I don't have a pic of the back - it's almost as gorgeous as the front. For the "Dual Showman" 2x15", I am going by the specs I could find and other people's builds, and it fit what I was looking for better than the Bassman cab. I also saw rare Ritchie Blackmore and Jimmy Page videos, and I was pretty much hooked. Well, I like the 8x10" idea too, but 2x15" is more than plenty.
The brace I figured was for structure strength and possibly to seperate the drivers' air space in case one blew, it wouldn't take the other one with it. I blew 2 subwoofers that shared the same chamber and all the "experts" say one could have been saved if it was in its own space. I went ahead and glued it in, and I guess I'll find out what +2ft^3 sealed per driver sounds like. I can also do stereo The joinery is not the greatest, but I'm not going on tour or gigging to constitute dovetails. My dovetails are worse than my playing, and I think it will hold up for years to come.
If shipping charges weren't so high, I'd probably be selling these and building more. In fact, I'd sell the 2x12 right now if the speakers weren't blown. One speaker still sounds great if you can get past the rattle of the motor. ;D
Now to trim the baffle and back cover to fit tolex and grillcloth, sand, paint, glue, stretch, jam some more - lots left to do.
Replaced the 15" pro DJ speakers with Celestion Trace Elliots, and man it sounds way better and EVEN LOUDER! These have the highs the others were missing as well as low-mid for the full sound. I'll get a video as soon as I get my right side to quit acting up on me. It's gotta be the fatigue...
That's called 'damping', and most guitarists don't pay enough attention to that particular detail. (Bass players, on the the other hand.....)
Ahhhh, I always thought damping had to do with the amber nectar, as mentioned earlier....LOL. And all of the Bass players I have known excelled in that area!

I got the new nickle corners today. These have lips like I thought the others had. I didn't put them on the Showman because I was chasing down a wiring problem that turned out to be the cable. Then I got sidetracked when I found out my crappy non-coordinated playing sounded great!
Anyway, here's the 2x12" with lips and I remembered the back this time:
