Proac response 2

i have a pair that has the surround foam rotten up, thinking about ordering new pair which cost about $500 ( original factory midbass driver)through Proac distributor, i was told these drivers are scanspeak special made for Proac,the least expensive way is to have them refoamed, anyone has them refoamed and how do they sound? also where did you get them done? the last choice is i have to order from proac distributor. Any info's will be appreciated and thanks in advanced
