It is true that most digital filters sound horrible, but cheap analog filter is worse. Weiss digital mastering EQ or some mastering grade computer softwares sound much better than the most opamp based analog filter out there, and they are much more versatile. You can even blind ABX test with them. The problem is you need multiple DCS.

what is this 'mastering grade'? Sounds like a marketing term to me!

Texas Instruments have published lots of info on how to use their opamps for active crossovers. Some is very simple, some is more complicated and some goes pretty deep. You read and remember the bits you can understand and ask about the bits you can't follow.

I guess some companies use the term for their marketing, of course, but mastering guys are very selective. Those mastering products are designed for mastering purpose, so it is technical, but most of them are rejected by mastering people. You will find only a few products that are actually used.

Mastering <>active crossover. Bob ludwig for example may use a weiss box for mastering, but he isn't using it as an active crossover or room management system. So I am really not sure where you are coming from on this.

I just said that DSP option should not be instantly omitted from OP's active crossover's list, because some of DSP based filters sound better than most of the other option available, whether digital or analog. I actually use one of them for crossover purpose.

The point is all DSP filters are not the same. Some are much better than the other. It's the same thing with the analog filters.

TI also has "freeware" "Filter Pro" which you can use to good effect.

Walt Jung's "Op-Amp Applications" should be on your bookshelf too.
