Looking for FIR capable DSP

Sure seems like a great DSP. I am going to look into that!
Until you find out what it costs ;) in that budget range there will be more pro-audio options available. Look at Q-sys stuff for instance…
 
Hi. I recommended the BSS London-806DA. It meet all your needs plus more. You can choose between two sample rates: 48K or 96K. I recommend 96K, it will give you less latency and your FIR will take less time. Pictures below of your case setup. Each FIR filter is using 4096 taps. The max is 6700 taps per FIR filter.

Extremely expensive.
 
At this moment of this post in Ebay you can get a used BLU-160 for $700.
Much cheaper than a minidsp Flex HTx or DDRC-88D.
But true, great power comes higher price!

Thanks! Yeah it is very expensive and also only 4 analog outs..i would need 6. (Pair of 3 way speakers, tri amped)
Perhaps this solution will suit you. This board was developed specifically for an active three-way speaker system.
One ADAU1452 has 10,000 counts, for two speakers you will need two boards, i.e. in total you will have the desired 20,000 taps. If you really need an analog input, then any ADC that has an I2S output can be connected to this board without any problems.

Very interesting board you designed there. I am very tempted.
This approach has been tested by time, and everyone who tried these boards in their projects was satisfied. There were no board returns. This is a fairly flexible configuration that allows you to use the boards both together and separately. At the same time, there is no need to worry about speaker protection schemes. All protections are already taken into account in the board's operation algorithm. Well, the Sigma Studio itself, together with the adau1452, allows you to implement very complex tasks using a very user-friendly graphical interface.
 
I was thinking about getting a adau1452 eval board and some i2s DACs, but yours is just a readymade solution. I was looking into Hypex FA boards aswell but using Sigma Studio seems to be a very flexible solution with many more options.

That's right, direct access to DSP using Sigma Studio capabilities allows you to do very complex things. For example, I implemented emulation of tube amplifier distortions, while I could use an external potentiometer to adjust the level of distortion when playing music, which allowed me to determine my own threshold of hearing this type of distortion. By the way, this project is in the folder that I attached to the first message in that topic, and here are the measurements in post number 21 https://www.diyaudio.com/community/...h-dsp-adau1452-100w-per-channel.410804/page-2.
And this is all just the tip of the iceberg, in Sigma Studio you can do almost anything you want if you delve into digital sound processing.
