To make a 6th order bandpass box for a 12" type R???

I have tried two different "slot port" boxes, and am not happy. .

I'm just not sure if I can fit something like this. .

I have about, 15" x 19" x 32"... possible?

Yep.

Go 1 cube sealed, and 1.25 ported with 25 sq in of port 16.75" long. Sounds great and drops low.

So I could do it?

I will need someone to design me one. lol. . .

anyone bored? lol

Just wake whatever I said and see how you can fit it into your dimensions.

Thanks for the offer, but I enjoy making boxes, and need to get better!:)


and yeah.. I have a question about the "port length" though.. I never understood where along the port you measure. . .

like straight down the middle? along the outer wall?

You will have room for 6th order also, Probrably gonna be just a tad larger than the 4th order,

About 5-6 cf for a 6th order to get a nice flat response from 20-60hz.

So no, I don't think it would fit. A 4th order would probably fit, but different sound from a 6th order.

Well I would be right at the 5cf mark with those dimensions I posted. .

So that means the ports would be really close to the side walls of my trunk. Would that effect output?

You should have about 4.5-5 cu. feet, if that's not enough for that driver to perform get rid of it. When doing a bandpass in a trunk car, keep in mind that if you port "through" the rear deck it will sound much better.

If you want peaky SPL bass it might work.

Well. . . I DO have a type R.. lol, so yeah, I really just want to get loud.

I can always swap boxes.. I have an extra R laying around. . .

You need to take into consideration the thickness of the walls and inside baffle. You could cut the airspace down slightly but that would detract from the benefits of the bandpass. Unless you have the dimensions to go bigger then a simple ported box would be a better choice than a compromised 6th order bandpass.
