Massive Audio FX Series FX4 4" 2-Way Coaxial Speakers are designed with high-tech sonic performance in mind. Each car speaker has a mounting depth of 2". These rugged speakers come equipped with high-powered Y35 strontium ferrite magnets contained in heavy-gauge, powder-coated stamped steel baskets. This ensures sufficient magnet force needed for high sensitivity and accurate sound reproduction. Speakers feature a 1" high-temperature 100% pure KSV coil that floats on a high-quality cloth spider with polyester fiber and custom fiberglass cones with soft butyl foam surrounds. The result is a sonic balance of quality audio and high volume output. A custom-made tweeter plate with built-in 6dB Linkwitz-Riley crossover connects to a ferrofluid-cooled 20mm inverted aluminum dome tweeter for smoothness and definition. These high-end car speakers also feature a custom-designed pole piece for low distortion and sound quality and fully isolated tinsel leads to eliminate crosstalk. FX4 speakers offer power of 50W RMS, 100W max and 200W peak at 4 Ohm. You can make them your own with the 2-piece custom paintable metal grills. Combining heavy-duty construction, great sound and long-lasting performance, the easy-to-install universal FX Series coaxial speakers produce high-end sound for car-audio enthusiasts.
