I've heard some conflicting arguments about whether there is an advantage to pulling a vacuum on a completed enclosure. From a perspective of making sure your enclosure is sealed it could make sense, but i wonder if a sub would perform differently in a state of vacuum. . I'm new to this forum and a rookie in car audio, so go easy on me if this is the dumbest thing you've ever heard of. If there is any benefit to this, I'd like to know why. thx, Mao
A vacuum? Do you mean creating an air-tight enclosure and then somehow sucking all the air out of it? No, this would be a very bad idea indeed, and would in fact be impossible with many woofers. The air inside the enclosure is an integral part of how a loudspeaker system works.

Support the12volt.comSound is a series of pressure waves. These waves need a medium to travel through.
Nothing to travel through, no sound. AkA -"in space, no one can hear you scream"
Besides you would destroy the woofer as the atmospheric pressure tried to fill the void.
as for the "theoretical" sound if the woofer could sustain the vacuum? Well, the amount of energy to mechanically move the woofer would be enormous. So i would expect the woofer to not even move at the rated power.
