Product Details

Morel ST 728 Supreme 1-1/8" Soft Dome Tweeter Pair

Innovative engineering and an advanced approach to acoustic construction are the reason for 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.
