I just put a Weber 12F150 in my Blackface DR.
It sounds great until I use the footswith to turn on the reverb, then it's like I hit a super overdrive or something.
It's alot louder and some breakup and buzz going on.
Is this caused by the bigger magnet in the new speaker? I think it must be because I can take it out of the cab and it sounds good, maybe just a little increase in gain.
Will wrapping it in foam or something allow me to put it back in the cab, or will I need to do something else?

A'way back in ought-9, I noticed the same thing when I went from two Jensen p10r's to two Weber 10F150's... I didn't get any replies, but I'm convinced that those big honkin' magnets were gettin' fresh with them little springs. I'd read other reports of that and most people saying it was doubtful that it could make a difference, but I was convinced it did.
Here was that thread (my observation at the bottom): http://www.tdpri.com/forum/shock-brothers-diy-amps/187765-reverb-tank-expectations.html (//http://www.tdpri.com/forum/shock-brothers-diy-amps/187765-reverb-tank-expectations.html)
I moved the tank as far away as I could inside the cabinet, and I think I may have switched to a "Mojo" 2-spring tank. I know I was swappin tanks left and right for a while. When comparing Accutronics, Belton, and Mojo a couple of years ago, I liked the Mojo the best. Specifically, it was the:
M4AB3C1B Mojo Reverb Tank (Fender, Marshall, Ampeg 2-Spring)
It either went in to that CVR or my silverface Deluxe Reverb. Don't remember right now.

I can't move it but about an inch farther back than what it was and that did no good.
guess I'll get some foam to wrap it in and see what that does.
It sounds great sitting outside the cab, but tatally unuseable ion the cab.
UPDATE: I didn't feel like going someplace to buy foam, so I cut the bottom out of a beer cozy and halved it for each end of the reverb pan. Screwed it in loosely and it made it work right. Sounds very good now.
Man that Weber made it a good bit heavier.
