well, i've designed a few boxes tonite using some jank *** windows program, but its the only thing on my computer that seems easy to use for this. but i designed 2 ported boxes. im not sure what woofers im going to use for this yet. most likely 2 10 inchers. the first box has a gross volume of 2.25 cu. ft. per chamber. and i haven't quite yet did all the math for the second one cuz i just finished it a few minutes ago.

the first one, having the woofers aiming into the driver and passenger seat, slot ported on the bottom also aiming forwards. and an amp rack on top.

the second box, has the woofers mounted on top of the box, aiming twards the roof, with round ports aiming forward into the front seats and an amp rack in between the two ports

so. i've read that low frequencies aren't directional like higher frequencies. so does it matter which way i "aim" the woofer? im trying to get the most quality over loud. is there any way i can up upload the designs so i can show you guys for a better understanding?

tahnx alot

 

i say try woofer up, port firing sideways out the passenger side

 

It doesn't matter for sound distribution because very low frequencies are non-directional and spread a lot.

BUT: the distance between the speaker and the nearest surface, and/or the distance between the port and nearest obstruction can actually affect the tuning and resonance of the resulting system.

You may find that one orientation sounds better than another, but the overall coverage generally doesn't matter.

 

If you aim at the seat then you will get more seat vibration from the shorter distance but i have mine that way and get a nice massage in the morning haha. Beyond that...no bass is not directional.

 

ok, well, both boxes are designed to fit under the the little pull out tarp thing, so i can hide it. and if i go with slot ports which would be a little more difficult to make. they would be on the bottom of the box. and would blow under the front seats. the round port however, to my understanding, is suposed to be as far away from the sides, or walls as possible so they would be in the center of each chamber blowing into the back of the front seats, a good 4-8" away. is that too close?

oh, and any idea's on how i can upload those images to show yalls, thanx

 

Loading a woofer off axis of a port though can have an effect on wave loads in a cabin. Depending on design, wave obstructions, direction of port etc etc could have a benificial effect, or negative effect for the total outcome of sound.

It's not really something though that can be calculated without EXTENSIVE backround research and R&D for your vehicle and enclosure design.

For the most part, you probably won't tell a difference.

 

Ha ha, we're in agreement on that.

If it sounds good, it's fine...
