towards a vanishly low distortion crossover

I am working on an input stage to marry with my latest speaker design (12P80ND + HF10AK).

Here is the input stage thus far.

Simple balanced instrumentation front-end, high-pass filter for subsonic filtering, and a shelving low-pass filter.

The signal chain may be quite long after the buffer downstream to the woofer and the cd.

I'd like to maintain a transparent signal, if at all possible.
