my biggest concern about Spirits and Reveal would be back fireing bass port. this, when set up wrong can cause major headache.
also IMO speaker to have decent bass response needs at least 8" driver (for example Yamaha MSP5 - i am not sure what, but something is not right there, probably i am to used to NS10s tho

which leaves PS8s (i have not heard them), Mackies (sound fab but pricey) and possibly Tannoys System800 - friend had their ancestors, also with coaxial driver and i loved sound of those.
now back to my home studio, i have to figure out what possible use might be from 4 strings in my bass (have to learn to count to 4 first

cheers
