Custom-Designed Drivers with Aramid-Fiber Cones Aramid fiber is employed in the woofers of all ELAC Debut passive speaker systems. Aramid fiber offers a superior strength-to-weight ratio and improved damping characteristics over conventional paper or plastic drivers. This added strength means arriving at designs that achieve a broader bandwidth with smoother response. Silk-Dome Tweeter with Deep-Spheroid Custom Waveguide The waveguide surrounding the new ELAC high-frequency driver features a custom, deep spheroid profile to improve directivity control and shield the dome tweeter from cabinet diffraction modes inherent in traditional box enclosures. Intricate Cossover A custom multi-element crossover with high-grade components in each speaker ensures smooth transition between the drivers. Robust Cabinets Every ELAC enclosure is engineered for the long run with thick MDF outer walls and a luxurious textured vinyl finish. The cabinet of the F6 incorporates specially designed internal bracing to add stiffness and strength to the cabinet’s outer walls. This bracing greatly reduces cabinet vibration, which causes unwanted coloration to the sound. ELAC believes that the only parts of a speaker that should be moving are the speaker drivers themselves. Superior Build Quality Count the parts and look at them closely. These don’t look like the components that go in such competitively priced speakers, but rather, speakers that cost much more.
