Free (almost): Box o'drivers

I was the speaker engineer at Alesis for a few years and accumulated a bunch of evaluation drivers, primarily for the M1Active 520 monitors. I am under strict orders from my wife to get rid of all unused electronics (like that's going to happen). I'm appeasing her, for now, with these guys, which are decent Chinese samples. There are 10, 5.5" poly woofers, 4 assorted fabric tweeters and an 8" poly woofer. These aren't going to be mistaken for anything Scandinavian, but they'll make a decent small monitor with the right crossover. Pics can be seen here:

Unfortunately, the only reference design I have is for the active monitor. It's fairly complex as this has balanced inputs and various switchable EQ settings. I have the 5.5" driver LMS measurements and 3 of the tweeter measurements. The 520 cabinet was 11" x 6.5" x 7" with .75" walls and a 1.5" x 4" port.
