I wonder whether anyone here can assist me with information regarding the amount of FIR that Ashly,Dynacord,Nova (4 channels in and 8 channels out) or other hi quality multi channel active crossover/DSP have in their abovementioned devices ?
I think you'll have a hard time finding a high tap-count proaudio speaker management processor. Too much latency intolerance for their typical market.
On pure memory, xilica was the highest I can recall.
The installation processors such as q-sys offer quite a bit higher, you just need to build an xlr breakout panel if phoenix doesn't work for you.
I'm using q-sys at 8192 taps 48kHz

so what is the acceptable # of tap in live application? I would assume there is a difference between home and live because of the delay.
I think 15ms works. Other than for monitors of course, where near zero latency is needed.
My 15ms estimate may be a little above consensus, but not by much I think.
Guys have been tying mains to horn loaded subs with 10ft or greater paths forever....

About right. That's why the pro systems have low count taps, to keep the latency at minimum.
You may want to check Four Audio , they are applying downsampling in the lower frequencies which in turn gives high tap count.
Thanks you all for the info. It's quite frustrating to know that such a Pro Brands manufacture DSP with so few taps although I understand the difference in needs between home audio in which I'm looking for and live shows. I have heard of Four audio ,but I'm not familiar with it's qualities and I couldn't find how many taps their multi channel crossover/DSP has nor it's price !
Can anyone recommend me on multi channel crossover/DSP that has as close as possible to 64k taps for the sub,around 32k taps for the midbass,around 16k taps for the midrange and around 8k taps for the tweeters or as close as possible to the above mentioned taps ?

The Fir Filters can be partitioned and the latency can be almost 0 ms - look up brutefir and read
Possible if you use PC/software based products like Acourate or Audiolense. So the PC will be your "hardware" and you will need additional peripherals like multichannel DACs and similar.
Look up the member here Mitchba and his posts (also his blogs in the former Computer Audiophile, now Audiophilestyle). He even wrote a book about it.
Also take a look at this, will clarify somewhat (note it is 3 and a half years old and an update is overdue):
