Trying to Tune My Box To 33hz ..... I'm Lost!

[727Designs]

Do you have 20,000 watts to your subs?

LOL My exact thoughts.

[tonedeaf]

Small port with tons of power gives better mechanical control.

problem is the box is a bit small, so to tune it that low, the port needs to be longer than what you can fit.

6.6cuft before displacement, so you might have 5.6cuft after woofer and port displacement (unless you do invert the woofers)

the most space effective ports would be two 6inch round ports, but they'd need to have 90 degree bends as they'd need to be 20inches long for about a 33Hz tune.

do this.

of course, the fact that you have enough clearance to mount the woofers inverted suggests that you in fact have more room to build a box.

im gonna be pushing 2800 watts to them, I realize thats not 20,000, but its not exactly some 200 watt sub, I still want to do ported, but idk uhhh

the subs are facing like that because I want that space open so I can actually see out my back window

I just thought about it and realized how small I was thinking a port that is 4 x5 is, lmao, wasnt really thinking, im looking at doing a 8 x 10 port, that is 25 inches long, and 20 inches of it outside, the box, that would bring me to 33 hz, question is, does it matter where the port comes out of the box, and does it matter where the port ends up on the outside of the box, as far as how it will effect phasing and that, could I pipe it out of the lower bottom, follow it up to the top and have the port open up at the top of the box? being 8 x 10 big?

I just saw your build log, and clearly the box is nowhere near as big as it could be.

why is there all that space behind it?

I still have to have a spot for the 2500.1 amp, and do you see how the top of the box comes right to the hatch, also if it were any longer in that sense I would not be able to get it into the car, I have to bring it in sides way through the hatch, then turn it in the car and slide it back, and its already pretty tight to do that, I am building more stuff behind the box there to hold the amp and possibly 2 6x9's and a 3 way crossover, I realize I could have exteneded the bottom out, but that would only give me about 1.5 more cubic feet, and I need that room for the last amp that is freaking huge, lol
