[QUOTE="F150Matt, post: 56080, member: 543857"] I just called a few local dealers(two of them kicker dealers) they said that they dont always use a subsonic filter on ported L7's. Also said that they've never had trouble with L7's because they didn't use one. Just done play a 20hz sine wave through it, and when u compete play frequencies around the tuning point of the port. Just thought you L7 fans might like to know that. One of the kicker dealers was even recommended by KICKER as the best one in my area and they no subsonic filter wouldn't be a problem. [/QUOTE]
