DSP vs. active analog crossover vs. passive analog crossover. What is your take?

What is you take on the sound quality?  Any personal experience and knowledge on the subject will be greatly appreciated.

I use both an external xover and DSP.  DSP to tame bass that no xover can fix. The xover is to integrate sub better and let me use for movies too.  That being said DSP happens in Roon using focus fidelity software and convolution filter in roon.  Xover is the JL Audio CR-1.  They sound great together.  Of course Roon DSP won’t help vinyl people

 but if I had learn anything from the past, there is no substitute for large drivers. 

I agree 100%!

I've heard some of these systems but to expensive for me. I have a simple 3 way passive  fairly large Bookshelf but I don't for a minute think it can compare with what these companies are now doing. DSP crossovers, fully active, complete integrated systems, this is the future.

"I don’t have exactly the same problems like you since my horn is dual concentric from 22k down to 400 Herts (it might even go down to 200 H since most likely I would let the dual 12" low midrange speakers go full range). However, I’m interested to learn more about DSD and if nothing else I can use it as a tool. Do you mind telling me which DSD processor are you using? Thank you.

P.S. Are you really a king? Just kidding....."

 

 

No, thanks be unto God (if he exists), I am not a king. I suppose I was just in a funky mood when I joined this forum. Since I am brain damaged,(two TBI in the line of duty) rapid cycling manic depressive when I get in a funky mood that has an entirely different meaning from the usual one. On all the other audio forums I visit I use my real name, Don Reid. I wish I knew how to change my username on this forum to my real name. By the way the TBI didn’t make me stupid, just a bit crazy.

I use a DEQX DSP which uses PCM coding, not DSD. DEQX is coming out with a new line of DSPs, supposedly this quarter. I wish they would use the DSD, but I doubt it. Whatever they use I am looking forward to upgrading.

I use Bill Fitzmaurice designed HT Tuba folded corner horn bass bins driven by 15" woofers which at 200 Hz cross over to Oris 150 horns with AER BD3 drivers. The Oris AER combo plays the range from 200 Hz up to 8 kHz where Fostex t900a bullet tweeters take over. Thanks to DSP the system is remarkably flat from 25 HZ where the output is identical to that of the 1 kHz reference output up to a little over 20kHz. The roll off below 25 Hz is typical for a horn loaded woofer.

I place great value on the system being fully horn loaded. Horn bass is the icing on the cake. It lends a smooth continuity and rightness to the SQ that I don’t feel is achievable by hybrid systems mixing horns with other bass alignments.

Thanks for your interest.
