You need to have some patience I'm still painting the cabs. We tested the OpenDRC and found out it has a base latency of 15ms. This is too high for direct monitoring. Still searching for an alternative.

You may have just found out why to my knowledge no manufacturer of studio monitors uses FIR filters.

Very nice job on the cabs though!

Kii Audio and Grimm Audio use them, same for KS Digital and Neumann (KH80). The problem is not FIR in general, as it can be made zero latency. Usually phase linear filtering requires long buffer times, therefore latency can jump up to triple digits.

From what I've heard, most of the time there's a way to implement both linear phase and minimum phase to retain similar filter curves, but trade phase coherency with latency when needed.

Does the KH80 use FIR? We had the KH120 a while back but I didn't care for them.

It does. Check the specs and you'll see that they're implementing phase correction - Georg Neumann GmbH - Professional Monitoring

As for the KH120, I regard it as a very good monitor for the price. Overall I'd say that nowadays it's rather hard to find truly horrid small 2-ways.

Anyways - I'm closely monitoring this thread as I have a need for a very similar design. Good luck!

You're right but indeed with a bypass switch to go back to good old latency free IIR.
Would a Lake contour 26D be an option? It has very steep "linear phase" brickwall filters.
