Recently, my Oversized Orange 2x12 fell out of the bed of my friend's pickup truck on the way home from a gig. The cabinet is shot, but the speakers, a WGS Reaper 55hz and a Greenback, are both functioning as usual. (I tested them in a different 2x12) I'm looking to get another oversized 2x12, but save a few bucks and build one myself. I have experience building cabinetry and furniture, but never a speaker cab. I have a few questions. What kind of woods are most common, and how do they affect the tone? Are their standard dimensions for oversized 2x12's, or is it a range of sizes that don't really make any sonic changes between them? My Orange was closed back, but I've seen amps that have a removable panel to switch between open and closed, and I love the idea. Does this work well, specifically with an oversized 2x12. I used my Orange cab with a JTM45 clone and occasionally an OR120 clone, usually with my attenuator, to keep volume down a tad and go easy on the speakers, if that's important. I play a R9 with 57 Classics, mostly using the neck. Genre wise, I play Blues/Rock, in that Cream/Mountain strain, if that helps at all.
