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. Any advice on which to use? What to look for? Would this work? http://www.parts-express.com/pe/showdetl.cfm?partnumber=277-086 I'm thinking a crossover point of around 3.5kHz and an L-Pad? Thanks in advance.
