clamshells?

when trying to figure out the tuning on them should i count the baffles where the woofers are to calculate the tuning? or do i just make sure there's enough port length already with out factoring in the baffles from the woofers?

its like a regular box, count the inside volume plus poart and woofer displacment

i got all that i just dont know if you consider the opning where the woofer rest apart of the port or just the actual port on the insde of the box?

Look at my old clamshell.



The port is the port. The baffle is the baffle. The baffle, therefore is not the port. Because of this, the baffle should not be counted as the port.

thats what i was thinking until i saw this one

if thats the case the above picture box would be tuned ungodly high

the baffles has to play a role in the tunning also.. i need help

what you don't see in that pic is that there is a length of port running parallel with the back wall for each 3sub chamber.

i seee it..its only like 6"

wtf is so hard? its a triangle, you add woofer and port displacement. Someone failed geometry in 10th grade.

Do you see where it makes a 90 and runs parallel with the back wall? No, because the angle of the pic doesn't show it. More than likely it continues for a length after the 6 inches you are seeing.

I've always liked an idea of a clamshell in the GP. Maybe 8 10's and 4 5k's? LOL

Jextell rebuilding? Sounds like a good idea! Good luck man!

it doesnt follow the back of the wall

Thats gonna be tuned pretty high then. I still agree with gmonk, the baffle shouldn't be considered port area. Looks more like a tone box than a music set-up too.

he plays the lows like no other..white girl, chopped and screwed..tons of air is being moved..

thats the setup thats been confusing me with this design..

how many cubic ft is the box? that still plays a role in the final tunning...
