Abstract
Adjustments to an electro-acoustic transducer may be made to match the performance of a second electro-acoustic transducer such that a net inertial force generated by movement of the electro-acoustic transducers' diaphragms are substantially zero. Adjustments may include adjusting a moving mass of one of the elector-acoustic transducers. Adjustments may include applying an equalization to one of the electro-acoustic transducers.
