Funnily enough I'm just finishing the assembly of my active crossovers (6.2 channel, 3-way, 4th order Linkwitz-Riley - it's been a lot of soldering). Nothing gold-plated, just a shirtload of TL074s and associated passives, driving way too many channels of power-amp. Flat within 2dB from 16Hz to 22kHz (until I crank the bass a tad), Q is about 0.7 and phase is pretty linear from 35Hz up. Double-brick walls will quake and dammit, that's what matters. I'll finally get to retire the speakers I built in high school; they're going strong but look seriously ratty.
The audio people are 100x worse than camera people (OK, maybe not Leica) for snake-oil though; my biggest LOL was an article going on about a "muddying reflection" apparently from the listener's eye-glasses.
