Uber, I have had my Emerald Physics 3.4s for about 4 months now. 3 days ago I increased the toe in less than 5*s and BAM. Im still in shock
I have owned Accoustat 2+2s, which I loved but the servo amps were too problematic (now there are people who know how to stabilize them), but I love how open baffle throws a sound stage and the speed. After several box speakers I bought a pair of Maggie 3.5Rs which I could never get it to sound close to the 2+2s. I tried exotic fuses, biamping, pure silver jumpers, replacing the passive XOs with active XO,
For a couple years now I have enjoyed Emerald Physics KCIIs, which kicked the 3.5Rs arse and is super easy to drive. with ample solid bass in a normal size room.
I am confident you will love the Spatials, but the EPs can be had for quite a bit less money, if that's an issue for you
