Absolutely brilliant!
I was always a fan of the P1/AP2/AP3 range - i used P1's myself for a couple of years and still regret selling them, about 7 years on!!
The AP3's are very similar to the P1's but have a bigger cabinet and better quality drivers. The only thing to note is that they were always noted for their......er........"exuberant" treble performance and so need partnering with care if they aren't to completely destroy your ears!
The Exposures should be OK and i'd go down the bi-amping route if i were you.
