I'll be honest: cheapskate that I am, I've thought (more than once) about buying one of the truly cheap Behringer 2- or 3- way stereo XOsĪ final 'thought' (I really shouldn't even pretend to know anything about this subject!) - my impression is that any of the vintage 'brand name' consumer XOs, on the used (eBAY!) market are outrageously expensive. These offer (again, according to said guru) 'time delay for driver alignment, totally configurable crossover points, slopes, and horn eq, and pretty neat bass sculpting.' One model was the EV XEQ-2 (two way, methinks), which, according to the aforementioned guru, was a rebranded Altec component. There were several models, and apparently they can be a bit confusing, but as I understand it they are quite configurable (although some DIY may be required). One of the local vacuum tube hifi gurus says (very) nice things about the Electrovoice (pro audio, of course) XOs. I've been thinking (as much as I ever actually think about anything when it comes to hifi) lately about active crossovers myself, though I still know next to nothing about them. Thanks Ken those pioneers look beautiful, but the 850 appears to be a 3 way.Įach crossover has the same frequency cut off selections Classic vintage gear will be the one to think about.

Then there's always Audio Research crossovers, but they're selling for more now then when they were new. There was a Pioneer Series 20 crossover which was excellent but impossible to find. I've used the venerable Sony TA-4300F in the past with fine results, but that could be harder to find. In terms of versatility and sound character the Pioneer is going to beat anything less than the Marchand. If you're at all handy the power supply and coupling caps could be updated. In all likelihood the only thing needed would be to clean the level adjustment pots. The best one to try and find would be the vintage Pioneer SF-850 crossover which show up on eBay fairly regularly.

While it's been quite a few years since I operated a bi-amped or tri-amped system I venture that all of those crossovers, I listed above, sound pretty limited and would negate any of the advantages gained from this approach.
