Hellos! I just scored a super clean Peavey 212 MC cabinet from the local Craigslist. It is an American-made vertical 2x12 with Celestion G12K-85 speakers made in 1987 in Ipswtch, England. The top speaker is angled upward, Marshall style. The back of the cab can be removed from behind just the top speaker for a sort of mixed open / closed back set-up. There is a solid board separating the two speakers inside. The cab is made of 1-inch plywood, probably pine, and covered in thick, rugged, textured black stuff, not tolex. Here's the question: Why is the cab partitioned? Many 2x12 cabs are open inside. All 2x12 combos are open between the speakers, usually with a partially open back. Old Fender horizontal 2x12 cabs do run a center board to partition though... In this Peavey, there is a board between the upper and lower speaker, so removing the back panel only "opens" the back of the top speaker. When closed, the cab really doesn't give much air space to the drivers. It sounds tight and strong, quite good actually, serious quality from the Celestions, but I wonder whether sawing out that partition would open-up the sound for both drivers with the back panel installed. (Having the back panel off totally opens the top driver's space, leaving no protection for that speaker.) Has anyone experimented with a partition in a 2x12 cab versus not having the partition? And should there be any baffling material inside the cab? How would that change the sound? Again, old Fender 2x12 cabs had fluffy stuff inside. At the moment, I am just running the speaker output from my 1965 Fender Princeton Reverb to this Peavey cab. Holy sweet potatoes - it's incredible how big the amp can sound! What an impressive little monster. But honestly, some of the open, ringing tone is missing with the stuffiness of the closed Peavey cab. I assume some of that tighter sound is also due to the nature of these beast Celestions G12k-85 speakers. Maybe a roomier cab interior would be a good compromise? Please advise. Thanks!
