    Box for 2 XL m2 12s

    Im going for 3.5 internal after displacement. I have 6 inches I can use for port height, if shorter is better thats fine, External slot port wrapping up the back side of the box and extending out the top firing rear. What length and width do I need for 1 port tuned to 32hz. I have a little something in paypal i can send for a good solid answer. I want output and lows. A hairtrick port, with decent numbers.

    For sure. Well either one of them can for sure help with design.

    Re: Box for 2 XL m2 12s

    I want to see if this will work.
    Can somebody tell me how many sq inches of port this is? 3.5 internal after displacement: 12 inches wide, 3 inches tall, 30.4 inches long slot.

    Re: Box for 2 XL m2 12s

    36sq in of port opening and 10.28 sq/in per 1 cube of airspace...... WAY too small!! Shoot for 50-56sq in (14-16sq in per cube) of port area. This will require the port to be longer as well. The port size and length you just listed has a tune of about 28hz btw.

    I concur for this situation.

    If you can get me t/s parameters I'll tell you what I would do.

    That comes out to a slot: 16 inches wide, 3 inches tall, and 35.34 inches long. That should move air

    So then why is your port limited?
