DD9512 enclosure

[Tom82]

So, I've spent the last few days reading and reading and reading. I think ive figured this out, but thought maybe it would be a good idea to get some opions on what ive come up with.

DD says for a 2.75^ft enclosure, V=44^in, 20.5" long.

My trunk space allows for 15.5" H X 36" L x 15" D, taking storage space into consideration.

I will provide a sketch (sorry, its only been two days, didnt want to learn cad as well) with what ive come up with.

Feel free to modify for better dimensions withing limits.

Ok, first design was wrong. Realized that i calculated port length wrong. And measurements were a little obscure. Here is the revised design. Opions?

This is done on my phone. Sorry for poor quality.

Anyone? Is this a good design for a mixture of sq and deep bass?

I don't want to build it if im off.

buy a 4" port from psp-inc and run that. slot ports are no good, especially ones with bends in them.

Is there a reason a square port is not as good as round? Im going to have tonread into that

slot ports are no good, especially ones with bends in them.

And just where did you pull this notion from???

I have had several boxes with bent ports, and one with a folded port design, they were all exceptional sounding enclosures.

I too have designed, built and used dozens of slot ported boxes over the years that as was stated sounded exceptional....

So, it turns out there im an idiot and was completely wrong about my subwoofer model. Its actually a 2512. opps. Not that it matters. DD still recommends the the same enclosure size. I decided to go for a 2.5 ft3 net enclosure. v40, port length is 20.5(22.25 with 90 degree bend). Im pretty sure i have this right. I decided to learn how to use SketchUP last night. And this is what i came up with.

Yes or No? I'm new to this, im not asking for someone to do the work for me. i've done my research, im just looking for a conformation that im right.

I have a 9515G in a slot port , gets down & dirty , sounds very good

I have used both slot & PSP

both work well
