Talk:Engineering Acoustics/Sealed Box Subwoofer Design

Comments
Needs original figures to be created. Synchonize with the vented enclosure section (Jason) and the moving coil page (Joe Land). Try to go in the same level of details. Mention the basic role and benefit of the enclosure (suppression of the back radiation). --me513

Effective diameter
The physical diameter of the driver does not lead to the effective area of the driver. The effective diameter can be found using the following diagram: It is not immediately clear what that means. First it says one number does not "lead to" the other, then it shows a chart of one number "leading to" the other. From inspection of the slope of the chart, it appears that it converts from the nominal speaker diameter in inches to the effective diameter in centimeters, based on some guess as to how wide the non-moving area is around the periphery. 76.199.67.31 (talk) 20:44, 22 December 2010 (UTC)
