    Dual 15 L7 box design for fellow-forum member. Suggestion needed.

    I'm designing a box for a guy on another forum. He has 2 15 L7s, and since I have a good program I thought I'd give him a hand.
    Here's his PM:
    "hey, yea i can wait a few days... i drive a tacoma so i have limited space... my maximum dimensions are 52w x 26h x 19d thats MAXIMUM!... id like the box to be tuned to 32hz."

    With the dimensions he gave it's about a 12 cubic foot box. I'm looking more along the lines of doing a 10 cube, tuned to 32hz, using a couple 4" precison ports flared on both ends. I'm going to suggest he get these parts as well:

    Port: http://www.partsexpress.com/pe/showd...number=268-352
    Terminal Cup: http://www.partsexpress.com/pe/showd...number=260-303

    The final dimensions I've come up with so far are 50 x 18 x 25 (external, L x W x H) & can't decide on the ports. Here's some pics of the design I've come up with. Let me know if you guys think this will suffice. It's for a first time box builder, so I don't want to go with anything too hard (thus the aero port & not slot port)

    Box:

    2 Ports:

    3 Ports:

    Should I suggest 2 or 3 ports?


    BTW, mounting depth for the 15 L7 is less than 8.5".

    Thats not enough port area...for 15s I would want at least 70sq inches of port...AT LEAST. where as you are only using ~36 sq inches...either design up a slot ported box, or use more 4 inchers or 3 6 inch aeros.

    I'm not sure what you mean. I take it your talking about how to get the pictures to display. For some reason, a couple weeks ago when I would post pictures they wouldn't show and would instead show the image link. Care to explain what you're saying to do?...
