Best Active Crossovers?

You have to be careful purchasing active crossovers for speakers. Some (not all) speakers need some sort of wave shaping circuitry to correct for issues inherent to the specific speakers. Martin Logans for example. So, when thinking about purchasing a third party's active crossover, contact the speaker manufacturer first and ask if wave shaping is required or if the third party active crossover will be okay for the speaker.

Minorl , that be hard with the Dunlavy's - and with the Digmoda you can do all the "shaping" you'd want.

Marchand XM44 is good.

If you're using strictly digital sources, and you're open to something completely different....

You might think about a DEQX (or similar) digital domain x-over/preamp. These are 3 way units, so the mid and tweeter will still need to be jumpered. However, in addition to the overall theoretical advantages of crossing in the digital domain, these units also provide digital room correction (which I find compelling). This might be particularly useful to your application, because (as Minor1 noted) any missing notch filters or other FR correction built-into the passive x-overs in your speakers will be less problematic with DRC.

I understand that this is a different approach and not for everybody. Just thought it was worth bringing to your attention.

Can't think of any 6dB active analog xovers. Like the Digmoda idea but still wary about class D for tweeters. As far as a separate crossover, other digital options are Xilica (might be the best of the 'pro' stuff and stand-alone option for 8 out), Ground Sound, miniDSP and, of course, Behringer (no comment). Full-blown preamp/RTA/correction and up to 3-way are DEQX and Holm Acoustics (interesting tutorial on website). No law that it has to be entirely active, other than trying to duplicate or improve upon the existing passive PCB - particularly the mid/tweeter xover. Then, there's software/computer based xovers and RTA's. Thuneau Allocator is just one of many but really haven't done much homework here.

Hypex amps/modules might be interesting for this project as well. Not like the SC4 isn't big enough.
