My front consists of a pair of Absolute Towers and a 2C center. I haven't noticed any issues with mismatched sound/timbre form the Def Tech surrounds (though when I mounted them on articulating mounts and raised them above ear height, angling them down toward the MLP, when I reran Audyssey, it set their crossovers at 90 hz instead of 80, maybe from moving the passive radiators away from the wall/boundary?). My attitude has been if it's not broken, don't fix it.
I am a few months from moving my main sound system to a room in an addition that we will be starting shortly, so figured it would be a sensible time to make a change, but even if I can get decent money for the PM800s and find the NHTs on sale, I'm just wondering if I'll hear that couple hundred bucks difference.
To be honest, you can probably just keep the system as-is. Yes, there would be a better timbre match if you went with NHT's all the way around, but for movies and Audyssey it probably would be fine leaving alone. As for the 90 Hz XO, just leave it alone. Speaker's freq response are highly affected by room location and that may be the best setting for those speakers mounted.
If you do decide to go with the Absolute Zeros/Walls, I would actually choose the Zeros. The walls have to be 'hung' from a hanger and have no other option since there are not mounting threads installed. The Zero's with mounts can be adjusted (tilt and pan) which the Walls cannot. They sound very similar, but the flexibility for mounting is more important IMO.
