Product information "Morel ST 728 Silver"

Innovative engineering and an advanced approach to acoustic construction are the reason for ST 728 Supreme Series tweeters' superior high performance. Their underhung voice coils move in a significantly higher magnetic field and remain there at all times during operation. As a result, the Morel Supreme tweeters provide more linear excursion, eliminate intermodulation distortion, reduce power compression at high levels, and considerably improve low frequency reproduction.
