Long term stability: how is the long-term stability of the Manger sound transducer?
After the burn-in phase of 24 hours, the Manger sound transducer does not alter. Our own positive, long term tests have been obtained from recording studios which have been using the Manger sound transducers since the mid 80s. There they are driven daily at high volume levels for 12-14 hours. After measuring, no deviations from the original test protocol could be detected.
