Pro active speakers are still a possibility, but if I go that way I'd go for the higher SPL, 3-way midfield or "main" monitors. The thing is, these are designed to be flush-mounted, and at this point I think I'd prefer free-standing fronts.
They are not intended to be flush mounted but like any box speaker they will invariably sound better that way (no baffle edge diffraction and no comb filtering suckouts in the bass frequencies from rear wall quarter wave reflections).
The ugly boxy appearance of regular pro speakers and extreme prices of aesthetic consumer versions of pro main monitor speakers is the biggest hurdle - so I understand your dilemma.
HOwever, if you truly desire high amounts of SPL with crystal clear low distortion and low dynamic compression then I would urge you to think pro speaker models - most consumer gear speakers are not intended to sound good at high levels and most of the construction costs go into the high quality aesthetic appearance (beautiful finish) and not so much into the driver build quality. At moderate SPL levels the best audiophile speakers will be comparable or can often surpass the best pro designs - so what SPL's you desire to achieve is an important consideration.
Hooking up mega power amps to consumer designs to get high SPL's is, IMHO, a mistake...you will be disappointed by the dull sound of the drivers as they exceed Xmax and as their response compresses thermally.
