Romy, what exactly was bad, and how?
Honestly, my knowlwedge and objectives were in infancy back then. Also, it's been so long that my "memory" is probably crowded with parasitic ideas passing themselves off as memories. But I remember the 808 driver was quite maddening. My buddy and I wound up making tar-filled "511" horns and crossing them over at 800 Hz (still using basically stock Altec crossovers). This crossover was obviously too high for the 515/bins, but it worked out considerably better for the tar 511 horn than using the smaller tin can horn at 800 Hz or using Altec's 500 Hz X/O with the larger horn. That "metal" 811 is a ratty-assed horn, one of the worst, ever. It's probably not usable in any way.
I don't remember the 802, but if to do it again today, I would try to "make the most of" the 808's aggressive, spitty quality. This driver responded all over the place to various adjustments, and I cannot say that I was really systematic, with evolved objectives, during the short course of my experiments. I would definitely re-work the crossover. And the horn is shite. It's hard not to think of adding channels.
