Venturing into SET active system. Does a 45 have enough power?

Hello.

I'm venturing into SETs for a system I'm building and wanted to check my rationale with knowledgeable folks here.

I'm building a 4-way active system, with a pair of subs and midbasses to take care of frequencies below 400Hz with their own SS amps (400W).
Tweeters are 104dB/W and flat impedance at 5 ohm and midranges are being worked on but close to 103dB/W and 12ohm (minimum impedance is 8.8 ohm).

The system will be active and I'm thinking of using a Yamamoto A-08S to drive the tweeters and another A-08S to drive the midranges.

My room is 25m2 (269ft2) and 3m (10ft) high. So a medium-sized room.

Most of the music I listen to is not large-scale orchestra. Jazz, blues, and rock. Some is heavy on the bass dept, but that shouldn't be an issue. I usually listen at 85dB SPL, and sometimes at 90dB (as measured on a Radio Shack handheld SPL meter, C-weight, set to fast) - peaks of course are much higher.

I wonder if having a 45 SET to drive the treble (above 2kHz) and another 45 to drive the midrange (400 to 2000Hz) will be enough. What do you think?
