a sealed a11ms with the 7p
A11ms in butterworth sealed has F9-6) at about 70 Hz. 70-20k is abit over 7 octaves.

3-4 octaves for either would put the XO between 600-900 Hz.

Listening to 11ms now with digital 1st order 900Hz low pass there is still a surprising amount of HF content audible, and naturally it would be the reverse for 7p.

Over-generalised, I could see a5 vs a7 as a matter of mid vs treble quality for this.

A bit earlier in thread you mentioned 11ms does not make a good midwoofer, is that because of bass extension or other factors?

The bass extention is relatively poor. Low Qt, small Vas. In an optimum miniOnken for instance A7ms goes a couple Hz lower than A11ms.
