ESB Audio 3.6K3HE CX 3-way High-End Passive Crossover Alu E-Cap

ESB Audio 3.6K3HE CX 3-way High-End Passive Crossover

Main features

Passive crossovers are used in 2-way and 3-way loudspeaker systems to electrically direct low frequencies to the woofer and high tones and harmonics to the tweeters. In order for a passive crossover to fulfill its function without compromise, it must be able to handle extreme dynamic variations, the entire audio frequency range, complex transients and varying impedance of the loudspeaker load. ESB passive crossovers are carefully designed to complement the precise characteristics of ESB loudspeakers. Each crossover circuit directs the signal to the tweeters and woofers to maintain a consistent acoustic response across the entire audio spectrum. The 3.6K3 HECX uses a high-quality, discrete Alu E-Cap capacitor, a high-quality aluminum foil capacitor designed specifically for passive crossovers (tweeter and mid-range elements). It utilizes a much thinner dielectric insulation compared to the market standard. The use of a thinner dielectric allows for a capacitor with less "memory" and a much faster response. Compared to electrolytic capacitors, the Alu E-Cap brings more clarity and a slightly more natural high frequency balance to the audio system. Ideal for those who prefer a slightly brighter sounding system, while also hearing improvements in the overall naturalness/neutrality of the audio system.
