[QUOTE="John Roberts, post: 48970, member: 126"] Re: Crazy idea for a powered sub Yes, I hinted at that, but that depends on where the heat sink and localized hot air is relative to the port mouth and cooler free air, and amount of displacement. Clearly any hot air that goes fully outside the cabinet will diffuse and mix with cooler ambient air. The coherence of this volume of port air is not expected to maintain much past the port mouth. My judgement is that this does not automatically deliver a high percentage of air turnover, but any turnover with outside air is useful. JR [/QUOTE]
