"...what speakers would you recommend I check out that are 90dB efficient or more? I'm going to say no to Active speakers just because no one seems to have any to demo."
I take it that your quest doesn't include speakers that you can't demo, and that is certainly reasonable.
Must confess I'm not up on all that's out there in the $3k ballpark in high efficiency land, with a decent possibililty of being available for local audition (assuming you're not too far from a major metropolitan area). Coincident, Zu, and Klipsch come to mind... dangit, I'm sure there are others. You might have to call up the dealerships within driving distance, tell 'em what you're looking for, and see what they have to say. Most of the high efficiency manufacturers I'm aware of sell direct.
A note about "fullrange driver" speakers, which tend to be high efficiency but with relatively low power handling. In my experience, their clarity is degraded on loud, complex, bass-heavy music. I say this as a manufacturer whose first commercial loudspeaker was based on fullrange drivers (augmented with a built-in powered sub and a supertweeer), and can pass along my thoughts as to why this is so if you'd like.
Imo it might make sense to consider a redistribution of your expenditures between mains and sub so that you don't have one becoming the limiting factor long before the other. At their rated 200 watt input, the Dynaudios can do a calculated 106 dB (real world it will be a bit less due to thermal compression). The JL Audio F113 is rated at 120 dB at 50 Hz, so theoretically you're paying for an extra 14 dB beyond the point where the Dynaudios reach their thermal limits... and in practice the discrepancy is probably more than that, because the subs will be getting a lot more boundary reinforcement than the mains. Not that you're necessarily going to be playing at 112 dB or so, but the ability to cleanly hit high SPLs means that your system will sound a lot more lively and dynamic at lower levels.
