Crossovers...

[Sam Lin]

I'd like to do a complicated system with a lot of separate speakers driving different frequency ranges, and I'm worried about cancellation. It can be alleviated by a very high slope crossover, but the only one I know of is Sony's XES unit set to 72 db/o. Is there any other electronic crossover that can do a high slope? Is there any way to build one?

You can get 24 with some audio control units, my Image Dynamics is 24. I think the Sony does the filtering in the digital domain where the high order filters are just as easy to implement as a lower order filter. You can build a 72dB/oct analog filter but the amount of parts starts to get pretty high and the results can be less than good due to device tolerances.

Ok, thanks. It looks like I'll be working with Sony's unit then, should be interesting with all the processing it can do.
