For the mid and bass channels, it will be good to have at least 3-4000.

Thank you very much, I will wait for the information. I really like the product and once the final revision is ready I will probably buy it if has enough taps.
For example here is the amount of error for a high-pass LR4 @ 250Hz and 8192 taps.

As a heads-up, linear-phase FIR filters don't need delay correction and you could use far fewer taps in the crossover. Bonus: even FIRs with a relatively small number of taps have serious attenuation a couple of octaves past the -6dB point.
