i said you can't burn the coil in 20 years giving it it's rateing... and yes the surround matters, it's foam you can poke through it by poking it, other matterials are lighter, stronger, and last longerThey'd wear out. Subs are wearing items. Amps can last a long *** time but subs, no. FYI the surround doesn't matter anyway?
