Advanced Woofer Design

Advanced Woofer Design

Total Performance Begins with Design

Our High Excursion (HEX) surround technology allows for greater extrusion and less distortion. However, to facilitate the extra movement, longer voice coils were required. Meaning our Aluminum Sandwich technology was too heavy. To improve efficiency, our drivers were designed with cutouts arranged in the paper cone prior to gluing to the aluminum cone. The Die Cast backrest ensures strength under load, and a large magnet completes the custom driver.

Custom Designed BASH Amplifier

Custom Designed BASH Amplifier

All seven models utilize BASH technology. The discrete implementation of these tracking amplifiers allows for maximum voltage swing, providing all the power that is needed and additional dynamic power throughout the entire operating range of the woofers.

Auto EQ and Advanced App Control

Auto EQ and Advanced App Control

Placement of a subwoofer can be challenging. This is because typically they are placed in corners or hidden next to couches causing reflection, peaks or valleys. The principle of ELAC’s Auto EQ, is to remove the effect of the room by making a near-field measurement and comparing it to a far-field (listening position) measurement.

This allows a greater degree of freedom for placing the subwoofer where it meets all requirements. As the pioneer of APP-controlled subwoofers, all seven Varro subwoofers include our 3rd generation Sub Control 3.0 App with Auto EQ room correction and easy setup of multiple subwoofers.
