[QUOTE="ciaonzo, post: 6286714, member: 607015"] Doesn't matter if the trunk has a resonant frequency. Of course it does. But if the trunk has a higher Vas than that of the drivers then the Fs of the drivers will dominate and decide your "tuning". The system in the second picture is not from Coustic. It's from Servodrive. It's called that because of the servo style motor used, not because of a closed loop feedback correction system being employed. Those were designed to be used in very high output horns for outdoor venues and such. The car audio version that we would be familiar with is the Phoenix Gold Cyclone, the difference being the lack of linkage, belts, and cones. Instead the vane was directly mounted onto the shaft of the motor. This got way off track guys. [/QUOTE]
