The ECP-G6 is a 6.5 inch speaker set from Emphaser, featuring its innovative CRYSTALGRAIN compound diaphragm. The 25 mm fabric dome tweeter delivers detailed sound reproduction, while the crossovers are optimally tuned to the phase alignment of the components. With a rated power handling of 120 watts RMS and a sensitivity of 90 dB, the set ensures powerful and precise sound. Additional features such as the Emphaser screw terminal and strontium ferrite magnets enhance performance and durability. The set includes woofers, tweeters, and crossovers, all designed for easy installation.

The Woofer

The warmth of the GRAVITY sound is thanks to the new "CRYSTALGRAIN" compound diaphragm. It combines the high stiffness and damping effect of paper with the direct transient response of the quartz crystals applied on the top side. The diaphragm thickness is chosen to provide stability for powerful bass attacks and the necessary lightness for precise midrange. The durable surround ensures that the ECP-G6 does not lose any of its precise reproduction even at high levels and thus high diaphragm excursions. The clean, crisp bass foundation and its level capabilities owe to the strong strontium ferrite magnets of the mid/woofer.

The carefully selected components are mounted on the minimalist Emphaser FlowMax aluminum die-cast basket. The very open design with delicate struts gives the rear-radiated sound maximum freedom and minimizes unwanted reflective surfaces that could affect the sound. Despite its delicate construction, the design offers maximum stability. Another innovation is the new Emphaser screw terminal: although very robust, it requires very little space and ensures secure signal transmission with its solid hexagon screws and gold-plated contact surfaces.

The Tweeter

The 25 mm fabric dome tweeter impresses with its warm sound and can reproduce even the smallest musical details. The diaphragm geometry offers a uniform directivity pattern for excellent sound in various installation situations. Besides the low weight of diaphragm, surround, and voice coil, it is especially the deliberate omission of ferrofluid that makes the tweeter play so lively, spatial, and distortion-free. The protective grille offers high sound permeability and low reflections due to its very large opening area. The supplied mounting housing allows installation at two different radiation angles for perfect adaptation to the vehicle acoustics.

The Crossover

The components of the crossovers have been defined through intensive test series in the lab and in various vehicles to achieve the best possible phase alignment of the components with minimal space requirements. The result is authentic-sounding voices and instruments with precise stage imaging and impressive spatial depth. The crossovers are divided into a tweeter and woofer branch. This allows easy installation directly at the mounting location without having to lay new cables across the vehicle.
