Anyone tried using high pass filter with CR1’s and subs? Block port?

I run my CR1’s full range and bring my Velodyne subs at 40hz and below (actually a bit lower using their eq) with a steep curve (typically 36db but have the remote set to choose, 30,24,18,6)

Lately I have been toying with the idea of buying an analog hi pass filter to free the CR1’s/BHK300 amps up from possibly below 50 or 60hz., and running the subs a bit higher.

I am getting a good match and really love the CR1’s bass, but wondering if there is more to be had, or if the extra electronics in the signal path (which are all tube and balanced) will outweigh any improvement.

Also wondering if blocking the CR1’s port could be another way to accomplish this?
