The Alon Thunderbolt is very fast and tonally accurate - a real music lover's sub - plus it's relatively inexpensive too ($1600 list.) It integrates very welll with planars as well as Alon's own speakers. Give 'em a try. You might even consider a pair.
I like them slightly better than the RELs, which were by far the best I'd heard with Maggies prior to the Thunderbolts. (I now have all Alon system including the T-bolts.)
