Ok, I just reviewed the project with my wife, a 4.6 cu ft cabinet for a 12" Shivia I getting from Mike P.

I was doing well in my proposal till I said, "it is about the size of the end table". That didn't go over very well so back to the drawing board.

To be honest, with the materials I have (1 sheet of 3/4" MDF and a large stack of 1 1/2" x 1/4" oak flooring), I am having a hard time designing a 24" cube cabinet which meet our family room decor. It will be placed in a prominent corner so it must look nice.

I can vision a tall design, paint it a light color with the wood strips running vertical as trim. Or a column design with American craftsman style trim.

For the inside dimension, I come up with 16"x16"x 36" tall or 14"x14"x 45" tall. I have 4" precision port tube kit on order from Parts express.

What I don't understand, is the design of a SonoSub the same as a vented cabinet using WinISD?

Would I have to place some damping material (fiberglass) inside this design.

I have no issue with placing the vent on the top just like a SonoSub but I could use a 90 degree elbow and vent it to the back.

Thanks for listening..

Yes. It's about the net volume of the cabinet. It doesn't matter if the cabinet is square or round.

some people use fibreglass. I find egg crate foam much easier to wrok with. It's sold at Walmart as a mattress pad for about $20.

Thanks Mike, I hate working with fiberglass. When you should use damping material is still a mystery to me. I understand it can make a smaller cabinet act larger but this isn't a problem for my design.

The Adire Audio suggested cabinets says no damping material is needed for a 4.6 cu ft cabinet so I would assume my design would need to damping material. What engineering factors determine when to dampen a cabinet?
