REDCATT 61FHMX4 6.5" Aluminum Cone Bass-Mid Woofer 4 Ohm
Â
The REDCATT 61FHMX4 is a robust bass-mid woofer developed for extended frequency response and dependable performance. Its hard-anodized aluminum cone helps improve mid-frequency output while reducing harmonic distortion artifacts, making it a strong choice for compact two-way systems and other high-quality speaker builds.
Â
Built around a ferrite motor and aluminum basket, this driver combines mechanical stability with practical thermal and airflow considerations. The 38 mm CCAW voice coil uses a glass fiber former, while the optimized magnetic circuit includes air-venting features for long-lasting performance in demanding audio components applications.
Â
The 61FHMX4 is especially suitable for hi-fi, studio and outdoor speakers. The aluminum cone and NBR surround are produced with UV stabilizers, and REDCATT’s adhesive and dispensing methods provide waterproof seals in weather-exposed glue joints. This makes the driver well suited to projects where durability is just as important as sound quality.
Â
For system design, the driver offers an Fs of 35 Hz, 86.01 dB sensitivity and a Qts of 0.53. REDCATT recommends sealed enclosures for best overall performance, while compact bass-reflex alignments are also supported, including 8 liters tuned to 40 Hz for strong mid-bass output and 10 liters tuned to 37 Hz as a balanced general-purpose option.
