Conclusions

 Sealed boxes are small, but they don’t play very loudly.

 Sealed boxes require woofers with high Xmax ratings in order to handle lots of power.

 Vented boxes make much more bass and even more power can be applied.

 Vented boxes are bigger than sealed boxes.

 Woofers designed specifically for vented boxes often have low Xmax ratings.

 Bandpass boxes have one good feature—a big peak in the response of the car, but they’re

bigger than the other boxes and more difficult to build. Stay away from bandpass boxes,

unless there’s a really good reason to build one.

 Almost all JBL and Infinity woofers are designed to be used in sealed and vented boxe. Most

have big Xmax ratings (greater than 10mm)

 The only exception is the CS1014. It was designed SPECIFICALLY for a vented box. You can

use it in a sealed box, but only with a small amplifier .
