Why HiFi manufacturers don't make active crossovers anymore?

That Xilica is awesome and all I use now are pro amps and DSP's and the huge improvement over passives and consumer gear is large. I figure most people who want great sound have not heard a system set up with something like multiple amps and a Xilica and in truth avoid that because they want plug and play and don't want to have to learn to do things other than spend money.
  Active crossovers weren't  a popular thing until buyers started demanding more with home theaters for sure. In the pro world they have been recognized as the essential tool that makes great sound for a long time. A crossover has severely limited purposes and wont control gain nor do EQ or time delay and introduces it's own set of components that have no way of being balanced against the other speaker(s) and crossover(s)
  Find someone close by who has done this and investigate it in real life and if someone tells you passives are the way to go for best sound I would run the other way.

" There is just no freaking way that an expert passive crossover designer could give you that kind of dialed-in precision using caps whose values are stated in nice, even numbers like "1 f" or "300 uf"...caps that only have a certain percentage of accuracy and whose true values vary with temp and lifespan...let alone the fact that different gear will behave differently in different systems with different rooms and different ears - all of which can be compensated for by digital crossovers, EQ, gain and delay and that, practically speaking, just can neither be predicted nor be adjusted for after the fact with passives. "
 100% correct.

" Myself I still only use the Xilica + amp-direct-to-driver for subs duties, but my main speakers with passive cross-overs are also run through the Xilica implementing a high-pass filter only (no delay or PEQ is used as-of-yet). I am considering by-passing the passive XO in the bass horn of my main speakers to run them fully active - this would be interesting for a variety of reasons. Going full-active with the mids and tweeter compression drivers is something I’ll likely avoid for the time being. "
 That 3060 is what I run too. What do you have for a system? You are right about DIY and pro usage.

" Just looked over your setup via your profile - great to see you using all-horns as well. Do you use both systems depicted? "
 The set of La Scalas is not my main listener and has been sold. The big set however is and it is my daily listener. The twp piece La Scala is an industrial LS rebuilt to be two piece with 25mm Baltic Birch sides, rebuilt crossover, stock K-55V on the mid horn and a set of MAHL large tweeters with B&C DE10 drivers. It was an experiment that turned out really well and was built for a customer so they sadly are not active crossover people, YET! They drool over the big horns every time they are here and they are doomed because they have actually heard great horns properly set up.

Hey phusis that is a nice looking setup and I have heard good things about the lilmikes. What drivers are you using on the top section? I have a rebuild LSI bass bin I am thinking of making into a two way with a 2" compression driver for 500hz to 18khz . Are those Fastrac horns and were they made from stacked Baltic Birch? I have a CNC mill and I an thinking of making some mid horns too.

  I am a Crown guy too. Went the consumer route for a while and tried all that "painless one touch" room correction junk and never was satisfied. You just can't beat the price and clean output of pro amps with consumer gear.

"Midrange compression driver in the Uccello’s is the B&C DCM50, and the tweeter is the DE10 - also from B&C. The midrange horn is a "variation" of or slightly modified version of the Eliptrac 400 (the modification, to my knowledge, seems to entail the edge of the mouth of the horn, and how it meets the baffle here) and yes, it’s made of CNC’d, stacked birch plywood.

What’s the details of the bass horn you’re using with the 402 mids horn - does it sport a 15" driver, and how low is it tuned? Any thoughts on the 2" (exit) driver to use?"
  That DE10 is a super driver and the one I use on the MAHL tweeters I make. The bass horn uses the Klipsch K-43 woofer and is -10DB at 27hz and near full output as low as 31 DB.
  The 2" driver on the 402 is a Klipsch 1132. I am going to experiment with some 2" throat horns soon and thinking of B&C for those to since I am an OEM with them.
  The Crowns are nothing fancy and are xli800's.    A Xilica xp3060 is the brain behind it all.

hifidream what MiniDSP are you using? I am thinking about making some two way systems and providing some sort of preprogramed DSP with them. At $200 the MiniDSP 2x4 price is certainly right for doing this. What is the quality of the output?

quizzio those Hypex amps have a great rep with the Klipsch DIY crowd. I have never heard one though.


  I note the article also says the Crowns are pretty darned good and a great deal and the only caution of note was to stay away from demand levels that could cause clipping. I might try a Hypex one day but there will be no hurry to do so since the Crowns I have are dead silent and the bigger problem I have with good output is the music files which Audacity can fix. If Audacity can't then they get trashed.
