Modern foams supposedly outlast the older ones. Its a bit of a head scratcher. Who’s to know exactly what speakers employ the "new surround" technology.
I have speakers that are 20 years old with foams that are still holding up. UV from sun and artificial light and the gassing of of carpet and other materials will play a role in there longevity.
Arro's are fine sounding speakers in an appropriate size room with good amplification while standing at an optimum distance from wall. I can see some people being able to live with there bass response. I preferred mine with a pair of subs. But I like to feel the bass as well as hear it.
