I got a Dr. Bass 112LF for dirt cheap a while back. The Celestion BN12-300S that is in it and wired full range sounds pretty good with my electric but is lacking a little high end clarity with my upright. I'd like to add a tweeter and crossover but have limited space on the cabinet's baffle. Anything larger than a 3" overall diameter won't fit, which rules out A LOT of the options I'm seeing. In fact, none of the "pro audio" tweeters on parts-express are small enough but I've found several in the "home audio" section that would work.
Remember also, anything you put inside the cab, will change the internal volume, and thus, the cab's tuning. I would guess at the least, you would lose some of the cab's low end extension.
The tweeters I'm looking at maybe will be 1 or 2 in2 on the inside of the cab, so any effect they have on the cabs tuning will be negligible. My biggest worry is will such a small tweeter be audible in this setup.
