Redcatt 61FHMX4 4 ohm 6-inch Woofer speaker

61FHM mid-woofer was designed for outdoor applications, yet it will shine in hi-fi home and studio applications as well. Optimized ferrite based magnetic circuit with good air-venting features ensures long lasting performance.
Our engineers have chosen hard-anodized cone with rubber surround for this model. Both of these components are produced with UV stabilizers.

Further more, REDCATT state of the art adhe sives and dispensing techniques ensures waterproof seals in all weather exposed glue joints. Sealing to the exposure can be guaranteed by EVA gaskets or based upon a request by Form In Place Gaskets.

The audio system designers can rest assured we have extensively tested this product with UV exposure, salt exposure and waterproofing

The extended mid-frequency response allows the systems to be used with higher resonance frequency HF units. For the best performance in the audio systems, we recommend usage in sealed enclosures. In this model the aluminum cone further improves the mid-frequency response and lowers the harmonic distortion artifacts.
