4FR Mid-woofer was designed with outdoor applications in mind. All speaker parts are coated to provide good protection against weather elements. The surround, cone and dust cap are produced with UV stabilizers. Our state of the art glue application and glue selection ensures the glue joints are waterproof. Magnet circuit is designed around sizable ferrite magnet. Consistent and wide Bl field add to the well balanced performance of this driver. Polypropylene cone and dustcap are lightweight solution and deliver the highest levels of performance. Large surround roll extends the peak to peak cone displacement and greatly improves the LF performance. The best application is in 2-way or multi-way speaker systems that can be designed for indoor or outdoor usage in Hi-Fi or professional products.
