give us an answer to this statement in 10 words or less.

if you use more than 10 words your either stupid (because you have been asked to use 10 or less) or a ***.

this gave me food for thought, and i want more.

10 word response.

THE RIGHT PORT AREA, THE DD PORT

Most modeling programs that simulate box responses were written for home audio use. They are not suited for high output systems. The port area defaults are inadequate. The port area must be commensurate with cone area. If the port velocity gets too high, the port no longer functions as a port, you end up with a leaky sealed box, double bad.

Lets say we have a 12 inch speaker in a box, roughly 100 sqin of surface area. Many programs and manufacturer sites will suggest a 4" diameter port for a 12" vented box. A 4" diameter port has about 12 sqin of area. This is about an 8-1 ratio of cone area to port area. If the 12 inch cone moves 0.25", the port must move 2.0". It can handle this, but when the cone is moving 1.0", the port must move 8 inches! Now you've got a leaky sealed box.

You need more port area for a clean sounding, high output system. The DD port formula is this: 16 sqin of port area per cubic foot of box volume. The port should be 16 inches long. Remember, the port is tuned to the box volume, not the sub(s).

This formula was derived from 1000s of hours of in-car testing and 1000s of installs. It works. It takes into account the need for increasing port area for increasing cone area. When combined with our DD subwoofer box requirements, you'll end up with the perfect match.

It should say "you're" stupid, not your. I am not one to comment on spelling or grammer because nobody is perfect, but you are a wiener-turd anyways.

I think you just owned yourself, it's spelled "Grammar". //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
