Very high efficiency and extended linearity are special features of this mid-bass transducer. Very efficient heat dissipation is ensured by a radiator that is part of the basket design. The aluminum voice coil offer a properly aligned Q factor and a very high sensitivity. A specially designed Shallow Triple-roll surround guarantee a very low midrange distortion. Fiberglass former voice coil, polycotton suspensions and treated cone provide the very high power handling.
