[QUOTE="Tim Weaver, post: 48727, member: 317"] Re: Crazy idea for a powered sub AFAIK, the eons just put heat sinks in the port area that would be cooled by the turbulent air. In this case it doesn't matter which way the air flows, as long as it flows. The Peavey device used a trick port setup that created one-way airflow by using 2 different tuned ports, each flowing one way. This allowed the heat to be "carried away" from the speaker (or amp). The way Jon did that was by having little vanes in the port that were more aerodynamic in one direction vs the other. Kind of like the barb on a fish hook. It goes in, but it won't come out. [/QUOTE]
