I am thinking of having klaussudio.com build me a box for my two JL 13w7's and i need to know what i should have them tune it to, they recommend 33hz let me know what you guys think thanks
it all depends on what you want. That will be a good all around SQL tune as long as you have a subsonic filter set to around 30hz. I would tune a little lower to like 25 but thats me I preffer more SQ then SPL.
