Better check the woofer underneath if you haven't. Those are similar to my PS-10A's, except they have an 8" down-firing woofer instead of a 10". The foams might be rotted, but if someone refoamed them before sending them off then you'd best grab 'em as quickly as you can.
I've refoamed a few sets of ps10a, and recently some Ps8b ( drivers are front mounted in the "b" version ). Impressive sound. Cabinets arent as solid as id like but if they're not crumbling , they are fine. .
