Can you just close the back of a open back cabinet?

Hey all,
I have a TA 15, which I love, and use it with an open back 1X12 cab. I play a lot of corporate gigs, private parties weddings etc. It's wedding season now and here in California that means outdoor gigs. I lose all the tone and most of the sound with the open back. Can I just close the back of the cabinet with some kind of removable panel?
Thanks.

Sure. Or you could add a Thiele cabinet and have the best of both.

Mk IIA->C+ DRGX head "Cold Sweat" in GTS shell
1966 Fender Pro Reverb
DC-3 head
Orange Dual Terror
EVM loaded Thiele; MS-12 1/2 back
71 SG; 72 Tele; 76 White Strat; 77 LP Custom; 81 Goldtop; 05 Am Dlx Strat; 11 G0 plaintop

Tried one. Didn't really like it. Maybe with a different speaker in it.

Did you try it alone or with a second speaker cabinet? I'm not crazy about a Thiele alone, but love it in conjunction with a 1/2 back 1x12 cab.

I just closed the back of my 23" open back cab because I needed tighter bass (used with the ED). It works fine and helped quite a lot, but you don't get something for nothing. The closed cab does not sound as free and airy which I miss.

If your getting setup is not cutting outside, I don't think converting to closed back is going to solve your issue. Have you tried lifting your rig up. I use an amp stand for my Express 5:25 combo (similar in output to the TA-15) and that makes all the difference. Sometimes I also use an extension cab which does help at high volume levels
Triple Crown 50 combo
Electra Dyne and Royal Atlantic heads
Express 5:25 1x12 combo
JCM800 2203
Deluxe reverb reissue
Traditional 2x12, 4x10 and 23" 1x12 cabs.
