    L7 ported or sealed?

    what are you personal opinions on the best way to get my L7 runnin well. It will be running of a Ca-1200 amp at 2ohms, 900watts rms. right now i am leaning towards a 3 cubic foot ported box but still not sure. thanks

    if you go ported, it will have to be a big box.....l7s need really big boxes to even remotely sound well/get loud....

    Wait a sec that amp is only stable to 4ohms bridged and thats what that amp puts out bridged. What type subs do you have, dvc 4ohm or dvc 2ohm. If it is dual 2ohm then wire the vc's in series and bridge the amp. If it is dual 4ohm then wire each coil to its own channel and it will get 600 rms.

    Nope its either DVC 2ohm or DVC 4ohm. I'm not too sure if it comes in a SVC version or not.

    you're right, they're either 2ohm dvc or 4ohm dvc.

    Yup and for the Profile CL1200 and the CA1200 then you would need the DVC 2ohm so that you could wire the coils in series and then bridge the amp and get 900rms. Allthough that would prolly be a lil too much for the even the L7's so id keep the gains turned down. But if you wanted a sure enough loud burp and had a large ported box. Crank them gains up a lil and burp them suckers and your bound to be deaf

    lemme know how it sounds
    although i think you should go 2.0 cubic feet

    stuff it 50% with polyfill...also make sure the sub is broken in properly



    why run with the crowd ?
