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.
Why HiFi manufacturers don't make active crossovers anymore?
Hello to all,
On the recent days, I noticed that a lot of manufacturers of Hifi 2 channel systems, had plenty of options in a not so long past, of active crossovers, like Luxman, Accuphase, higher end Sony stuff, and many more, why do you think HiFi manufacturers abandoned the inclusion of active cross overs, channel dividers, in their lineup?
Accuphase still makes a digital one.
Appears that this devices are only still relevant in the Pro Audio world, why Home HifI abandoned the active cross over route? It's correct to assume that?
I think that can be very interesting tri-amp a three way loudspeakers with active cross overs, would like to know more about it too...
Share your thoughts about the subject, experiences in bi-amp and tri-amp with active crossovers and etc....
Thanks!

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 EN3020: https://www.hifido.co.jp/sold/11-62786-28291-00.html?LNG=E 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. |
Would like to know more active analog crossovers similar to this ones, in specs, and layout functionality, anyone have more recommendations? No DSP please.
