Deluxe reverb speaker

I traded a retired musician friend for his old, old black face deluxe reverb that needed work. A local shop went through it for me and got her up to snuff. BUT, there is a buzz when your on yer bass strings. I assume the speaker paper is torn or something like that. Anybody have experience with this and what should I do? Can you get that speaker fixed or is a replacement in order. Replacements have probably been addressed somewhere in the archives, but what one you you go to. It has such a thick, mellow, sweet sound that I'd hate to lose. Ideas?

'60s P12N.

The stock speaker in a DR was pretty lame and weak sounding. Usually either a Jensen C12Q, or more commonly an Oxfart 12K5.

If you really want to wake the thing up, put the stock speaker away for safe keeping, and call Ted Weber and put one of his P12N models (12A150) on order. You'll never look back.

Could be the speaker but make sure 1st. Try an extension cab if you can. Use the "Normal" speaker jack on the back of the amp by unplugging the plug that's in there now. If you use the "ext" jack you will hear both the internal and the extension cab.

If the speaker is an Oxford, upgrading it is a good idea anyway. Major difference when I put my Weber P12N in my '71 DR.
