Arrived in average amount of time. Just about 2 months to the U.S. The rubber surrounds I received are approximately what I expected, & seem to be of fairly decent quality, made of a butyl rubber. I didn't like the way these were packaged, folded twice & put in small ziploc bags. Haven't refoamed these woofers yet, but diameter seems appropriate & fitting to do a repair job. Bought these to repair rotten foam surrounds on a few old pairs of Advent, AR, Becker & Infinity speakers. While they are a different material, I expect them to have better longevity, & resistant to deterioration. Don't know whether the dissimilar material will affect sound quality, but I am just happy to be able to restore nice pairs of vintage, 80s speakers I have, that are otherwise in excellent condition. The only down side is that they do not come with the glue necessary to adhere them to the speaker's cone, and frame basket. I will probably use ordinary rubber cement, which should work fine.
