    DD 9518 Info

    Getting my first DD sub soon, as well as my first 18 incher. Just looking to hear some opinions on enclosure size/port size/tuning.

    Will be powered by an AB VFL 150.1 in the back of a Ford Explorer, so you have some room to work with. What's the best 5-7 cubes tuned to 32 or is that too low? How much port area?

    Tried searching but I didn't come up with much, thanks in advance for your opinion!

    Re: DD 9518 Info

    I've done several of them for daily: 6 cubes net, 96^2 port area, and tuned 35-36Hz. If that amp is only 1500watts you could go bigger, 6.5 - 7cubes net and do 16^2 port per cube.

    Base tuning on the music you'll mostly listen to. I've never tuned AQ/DD subs below 34Hz as they'll play into the upper 20's no problem at that tuning

    The ab vfl 150.1 is rated at 2900rms ..but wont do so unless ur running .5 with strong electrical ..safe to say around 2200 to 2500
