Why HiFi manufacturers don't make active crossovers anymore?

Similar to member chosenplay earlier in this thread, I am also using DEQX & Open Baffle speakers ’though in my case two processors. (HDP-5 - 3-way OBs as master & HDP-3 slave with two subs).

I am 62 y old, a vinyl listener since mid 70s & was extremely cynical about using DSP with an analogue source until I actually heard it in someone else’s system!

I then researched & auditioned/trialled numerous variations including Dirac, Mini DSP, Behringer, Acourate, even Linn Exakt in recent years but for me. DEQX provides by far the most satisfying results in spite of high cost.

The first time I set a correctly time and phase aligned crossover with corrected, time coherent speakers I literally swore out loud at the clarity, transparency, cleanness and sheer musicality of what I was listening to (this was with Shaninian Obelisks & a M&K sub that I had owned for years and knew the sound profile inside-out).

The phrase ’game changer didn’t come remotely close! (that was seven years ago & I progressed a long way since then with a setup that since early 2017 is as near ’perfect’ as I could want).

Any shortcomings that may (or must?) be present in terms of transparency are buried so deep in what I hear that the positives about absolute time/phase coherence (at EVERY frequency in the case of DEQX) completely overrule the negatives I never really appreciated in most purely passive setups that I had owned or listened to.

Any sceptics reading this - please keep an open mind before passing judgement until you hear a properly configured DSP setup

Sure DSP can correct issues and if your system has them then it is very useful. If your loudspeakers of proper design a DSP will have nothing to correct. 

Not true I’m afraid - it will be impossible for any passive crossover or indeed driver to be absolutely time and phase coherent across every frequency. Some of the high end digital algorithms do achieve that.

I have experience of ’correcting’ Shahinians, JBLs, B&Ws & Royds and in every case the change was very apparent & positive.

Some months ago I also did a ’quick & dirty’ crossover and speaker calibration to some Mission floorstanders for another forum member (prior to him using MiniDSP). We were both shocked by the huge uplift in coherence, smoothness, imaging and overall clarity achieved vs the original uncorrected and passive crossovers.

I’m not trying to be controversial so apologies it that appears too blunt.

I would like to know more analog crossovers similar to this models from Fostex, EN3000 and EN3020, EN3000 appears regularly to sell in Japan, the more sophisticated one EN3020 it's much more hard to find...

Anyway, would like to know more units with similar characteristics like this ones, very straight forward 3 way, easy to use.

For those who not know this Fostex, here they are:

EN3000: https://www.hifido.co.jp/sold/14-84210-27250-00.html

Thanks.

No DSP's recommendations please.

I think the ideal way to do active would be using the built in DSP and crossover function built into server software like JRiver.

It would require multiple or multi channel DAC, but it seems the least destructive method since no additional DA or AD conversions would be needed.

Has anyone experimented with this method?

I have dreamed of modding my TAD CR1's to work with an active crossover,  but I would not want to risk damaging such an exotic driver.

The other issue is I would want not to use amps of a lesser quality than my BHK 300's (with their tube input stage) and could not afford another 2 or 4 channels of BHK.  I have read about people trading their Pass amps for BHK 300's (perhaps because of the tubes)   Maybe a pair or 3 of the stereo BHK 250 would work.  They are doing a more powerful version, unfortunately not a lower power version for multi ways which would be ideal.
