3 15" x ones will be going into a wall in the back of my gmc yukon

which is the best place to put the port? top, bottom or side?

or which one of these will work best?




box will be strictly for daily driving use and tuned to 32-34hz

i want some input on which would be best for what i want

thanks

i was thinking 10 cubes before displacement of the subs and port

36 x 36 x 16

I would go for the one on the bottom right. And if you are building a wall but want a daily driver, I would make the port so you can change it for SPL contests, because if you ever enter one, and get beat by a street A car you will feel all yucky inside.

I agree with DWVW, the one on the bottom right, but group your subs as close together as possible while still being able to brace the baffle correctly.

Keep the port away from the extreme side of the box. Center the rectangle port in the remaining area where the subs are not. If your port is right up against the edge of your box, your box can see the door panel as an extension of the port and it will change your tuning.

X3 go for the right corner one in your design for dailys but down the road u are going to love your wall so much that u would join a comp for fun..... port on driver and maybe u can even put your seats init to HAHA have fun

Here is the skinney for SPL yo...

I agree that port placement as well as sub placement can effect loading... take note that at resonance the output from the sub cone will be at a minumum while output from the port will be at a maximum (will account for 3/4 of your output)

I might try to find the sweet spot for the port that will cause the greatest degree of loading at resonance where the mic will be placed....

ive actually decided to go with all three subs across the top just above the seats, and the port is going on the bottom

52.5 x 24 x 17.5

after displacment that gives me 9.6 cubes

im going with 90 sq inches of port(6 x 15), with a 14.5" depth so its tuned just under 34hz

when it comes to SPL comps, yea i might enter just to see what itll do, but im not too worried about losing, like i said before, STRICTLY daily driving, ill post some pictures when its all said and done

So you ask for advice, every single person tells you the same way, and you decide to do it differently?

thats not even one of his own options [img]graemlins/freak.gif[/img]
