ECA Series Full-Range Speaker

• Featuring dual woofers, the dual 8-inch and dual 10-inch models are equipped with a 75mm compression driver, while the dual 12-inch model features a 100mm midrange driver and a 65mm tweeter, delivering wide frequency response and strong penetration.

• The dual 8-inch and dual 10-inch speakers feature a built-in passive high-frequency filter with a toggle switch for 0dB, +3dB, and +6dB boost.

• Switchable internal/external crossover for flexible system configuration.

• Woofers feature specially coated cloth surrounds with excellent elasticity and durability for fast, dynamic mid-low response.

• Tweeter diaphragm made of aviation-grade material for smooth, detailed, and transparent highs.

• Equipped with a directional plane waveguide horn to control vertical directivity; multiple units combine to form a near-linear sound source with reduced long-distance attenuation.

• Symmetrical magnetic circuit design for low harmonic distortion.

• Crossover uses low-loss oxygen-free copper air-core inductors and high-quality PP/PET capacitors for stable performance and superb sound.

• Trapezoidal cabinet with internal acoustic foam reduces standing waves for clean mid-bass and flat frequency response; compact cabinet with flying hardware and pins, vertical angle adjustable in 7 steps from -2° to 10° for flexible radiation control.

ECA Series Subwoofer

• Features one 18" woofer, designed for use with ECA series full-range speaker.

• Woofer uses specially coated cloth surrounds with excellent elasticity and durability for full, fast, and dynamic low frequencies.

• Symmetrical magnetic circuit design ensures low harmonic distortion.

• Employs a bass-reflex design with an additional front chamber opening that functions as a horn; the combined output of the port and driver is compressed and

radiated through the front chamber, enhancing forward energy transmission and improving low-frequency SPL and impact.
