No, I have never noticed. I have seen some Foam surrounds go to shit though. They rot out with sunlight and whatnot...

the subs i have owned with rubber surrounds have low excursion.

I do prefer rubber though

Rubber is my favorite. I had some old school kickers 12 that roted out But they had been round the block a few times

This certainly is not a rule of thumb by any means...

Yeah your right because there are some really good sub with foam surrounds

I guess it just depends on what you like

they do make foam rubber.

Older type foam surrounds had varying elasticity and tensions depending on how warm they got with movement, and how far they were stretched. This is very bad. The longer you would play the subs, the more likely excursion will not be linear and distortion or damage will occur.

The older foam also deteriorated and dried out after a while of use.

The new type treated foam surrounds are multilayered and stronger.

My fi q was a foam surround and it had 28mm of xmax. So there can definitely be subs with foam surrounds and high amounts of excursion.

rubber feels better then foam //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Yes, Fi uses newer type multi layer foam that works quite well. I believe it is a foam rubber.

Not the older type foam I was speaking of. The older type I speak of is like the orange expanded foam surrounds used on Cerwin Vega XL woofers.

actually older rubber surrounds were kind of bad too. The newer ones are much better.

But new foam surrounds are treated and multilayer. This certainly helps with strength and integrity.

Most of my high end subs use a type of foam rubber whereas the lower end subs I have use rubber.
