pseudo-clamshell?

From what I under stand, clam shell boxes are supposedly louder. If you don't have two woofers to clam shell, couldn't you theoretically achieve the same effect by facing your port at the sub cone?

I dont think it would work that way. Because of the fact that clam shells have angled subs facing the same vector they don't cause cancellation. But facing your port at your sub well I can see cancelation being a problem though I'm not sure how you would manage facing your port at you sub anyway

Group delay between the port's output and the speaker's output will mean the port and speaker are out of phase with each other, which is why your idea wouldn't work very well. Clamshells place the opposing speakers in a position (angle and distance) that couples the output of the two, and the combined output is sent out in a vector towards the listener (or mic). With the delay in output from a port versus the direct waves from the speaker, coupling the two is impossible.

since were speaking of clams how would one go about figuring out a design for one?

I know I might not be the first person you think of when you think of box designs, but if been wanting to design a box like that, it you wanna give box dimensions ill draw something up for giggles

One last question would there be any benefits to clam shelling the ports?

i had nothing specific in mind, i just wanted to learn how to do it.
