- To build a box with two identical woofers sharing an air space, you
- calculate the volume as normal, but enter the Vas as twice the value
- of one driver. Note that the drivers can be mounted physically out of
- phase... or course this must be corrected so that they both compress
- the airspace at the same time... not electrically out of phase. The
- advantage to this is that lower driver distortion results as a result
- of the drivers being out of phase with each other physically.
-
- Note that doubling the Vas can be done in designing vented
- enclosures as well.
