So, I have this MG cab which sounds just barely ok, kinda shrill, kinda light on tone, but, it spreads the sound out and works well with my 1922. I do not want any larger cabs as I drive a honda civic, and a regular 4x12 or 1936 cab won't fit. The funny thing is the MG and my head will fit in the back of my car, so I got to thinking about upgrading the speakers. Now I know the cabs made of plywood, and thats not so good, but I was wondering if anybody had tried throwing something like the hellatone speakers in a cab like that or something of that nature. Would I need to reinforce the cab? Replace all the wiring? What would be a good mix of speakers? Would this be worth it in the end? Are there any other solutions out there for this type of problem? Another idea I had to kind of fill out the tone would be to make a new back piece to the cab out of birch and tolex it so it had a little more resonance, Any ideas on how to tolex properly etc would be helpful as well.
