Multiple woofers in a common enclosure

[ligs]

Here is a quick question. If my woofer works well in a 0.4 ft3 enclosure with a 1.5-inch diameter, 6-inch long vent. Using two woofers the volume of the enclosure shoud go up 2x. How about the vent diameter and the length? I tried google this but did not get an answer. Thanks in advence.

Not necessarily! Helps to know make and model of woofers!!!

It should help you determine the correct length and diameter port.

Good Luck!

Actually it really is pretty simple. If you arrive at an alignment you like for a given woofer, and you want to go with two of them The simplest thing would be to double the box size and add one more port exactly the same dimensions as the single one. This will result in the same alignment as the single woofer had. If you only want one port, then the diameter of the new port in twice the box volume would be 1.414x the original diameter but the same length as the original port. If that becomes a number that won't work because it is an odd size, then it back to recalculating the port size.

Thanks It is simple enough:)
