I honestly believe crossover design is overrated these days (for DIY). It was a necessity in the past, but today we have cheap amps and great DSPs. "The age of the active speaker" I'd call it. The smallest ADAU145x can do the crossover (and corrections) for a 2-way speaker. If necessary even as a FIR. Products I have are the freeDSP-aurora (8 channel DSP, 300€) and a Beocreate (4 channel DSP+amp, 170€). Both use the ADAU145x family, but the aurora is more powerful.
Of course this only applies to DIY. Though I wonder what's the cheapest commercial speaker one can get with an ADAU145x in a crossover-less design.
- jasonwatkinspdx 4y agoYeah, I didn't wanna just blather at people but I should have mentioned that with minidsp and all its descendants you can treat the crossover design as a software problem, which definitely simplifies. But also what I was getting at with mentioning the common room correction systems is these days, you can do something like take a textbook Linkwitz Riley 4th order crossover, do the little bit that's necessary to match levels, and then just call it good and let the receiver's DSP handle the large scale FR response. That advice might annoy some more knowledgable people, but the blunt truth is it'll work and done with reasonable care you'll have a truly impressive system for the price. I don't know pro gear that much but my understanding is there's a bunch of vendors now that package DSP + ClassD amps in a way the speaker companies can white label as their own. Kinda like half the AV receivers on the market are ultimately mildly tweaked Audyssey designs.
