    Re: Box specs for evil subs

    Seems like 3/4 cubic foot room per sub.
    Out of 6.50 and 7.25 is one better for 29hz tune and one is better for 33hz tune?
    Or is one size better for high power?

    What's displacement per sub?

    6.5 tuned to e3 will give you a more balanced flatter frequency response with the larger box and lower tune gives you more output and Lowend extention if you use.3 cubic foot subwoofer you should be in the ballpark

    Sub displacement should be .3 cubic feet.

    The tune and the Box off will vary frequency response the smaller higher Toolbox will have slightly better hi and extension in high-end I'll put meaning it will play up higher and louder and frequency while the larger lower tuned box will have better Lowend output and extension

    Re: Box specs for evil subs

    So it's a down to a box that will play a lot of the notes or a low end monster.
    Weird how a few hz tune can change things.

    I leaning towards 29hz and the bigger box.

    Re: Box specs for evil subs

    If it were me, I'd do 30Hz.

    Low end monster would be tuned lower, like 28Hz or lower. 30 and you still have a little upper freq.

    Re: Box specs for evil subs

    heck tuned at 33 it should still kill lows.
    May have to stick to 2 subs tho or ride steering wheel.

    I always hated sitting right up on wheel.
    But if I put batts in bed(tool box maybe) and do aero ports, plus use every inch of room for box that I can it would be close for 3.

    That would depend on thickness of box too. I'm going to re measure the room I have again.

    Tuning the port doesn’t mean how it will sound. The enclosure size and port size. 6cubed box tuned 30hz will be different from a 8cubed box tuned at 30hz
