Design Notes
The 30FF is a high efficiency, (85dB 1watt / 1 meter) 3-inch full range speaker with linear frequency response characteristics and high power handling capability while generating low harmonic distortion artifacts. The 30FF uses a lightweight exponential pressed cone assembly along with a NBR single roll geometry surround. The combination provides remarkable strength, high efficiency and sustained output under extreme conditions.
Power Handling
At the core of the 30FF is it’s voice coil technology featuring a Kapton former material capable of withstanding peak temperatures in excess of 240C, well beyond the thermal requirements of modern professional audio systems and providing optimal structural strength and thermal characteristics. Former strength provides the ideal transfer of power between the voice coil and the cone assembly and assists in reducing distortion artifacts. By combining this material with state of the art adhesives and our winding voice coil technology, the 30FF delivers very high performance.
The best application is in column speakers, two-way and multi-way audio systems. Due to its good HF extension, the HF units are not required.
