I was referring to using digital processing, a DAC, and separate amplifiers versus one amplifier channel and a passive crossover, for the same speaker drivers and enclosure. I wish there was a reasonable way to do an A verses B test for a speaker system by switching between a passive and active configuration quickly for the same speakers. The only speakers I know of where there are active and passive versions of the same speakers are some of the Klipsch Heritage models (analog active crossover). I really wish Genelec would come to Washington Audio Fest and demo some of their SAM speakers -

I think DSP is perfect for subwoofers only, anywhere else in the system and you get noise and distortion. Nothing beats a well-designed and sorted passive xover.
Why would anyone put all that crap between you and the music is beyond me.
Forget about the bits and bytes and listen to the music. Go to a live musical event and listen to what real music sounds like then go listen to your system and compare.
Numbers mean absolutely nothing, listen with your heart and soul not your brain and get off the equipment go around circus and chaos.

If -- and I mean IF -- high-end (aka. uber-expensive) speaker manufacturers could produce the same product that served the music deserving the high $$$ using electronic crossovers and discrete amplifiers for each driver they would.

But they don't. WHY? All of the extra electronics to serve the speaker's needs goes a long way to corrupt the critical path. Any system that I have auditioned utilizing electronic crossovers (the guilty know who they are) had an "electronic" quality to the playback that was "shouty" with a hard-edged quality that was not musical.

Paul was totally correct about attending live events -- especially live events without sound reinforcement. Anyone on this blog with the DIY chops that compares their efforts with other playback systems is on a "fools errand."

This game is all about creating the best possible facsimile of live music in the home (or man-cave). When you are "there" it is as if you are listening to the direct-feed from the mixing desk and not listening through a couple of generations of magnetic tape and the cutter amplifiers. Even direct-to-disk recordings can sound flat and hard through an electronic crossover based system.

The best digital playback sources are easily compromised the same way. That medium is getting better as the years move along -- and not hearing what is now possible with digital playback sources is sad and prejudiced.
