ELAC Varro Premium Subwoofers: Total Performance Begins With Design

Eliminate the challenges of placement with ELAC‘s AUTO EQ.

ELAC’s new Premium subwoofer series provides unbeatable power and performance with a sleek, modern design. These new models deliver huge performance at an affordable price. With advanced features such as BASH Amplification, Advanced App Control and ELAC’s revolutionary Auto EQ system, the new Premium Series is the perfect solution for completing your home theater or music setup.


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

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

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.

Product Specifications



Robust 1-3/16″ Thick Cabinets and Internal Bracing

Each Varro Premium subwoofer is constructed using 1-3/16″ (30mm) thick MDF cabinets and internal bracing greatly reducing cabinet resonances that could negatively impact audio quality.

BASH Amplification

BASH is a unique amplification method that offers the efficiency of Class D amplifiers, however still utilizes a CLASS AB output stage. BASH monitors the incoming audio signal and adjusts the power supply dynamically to deliver the energy necessary to reproduce today’s demanding movies and music.

Auto Room EQ

One of the most challenging aspects of adding a subwoofer to your home theater or music system is subwoofer placement. Bass frequencies integrate into each room very differently than the way higher frequencies do. Our unique AutoEQ makes automates this process by tuning itself to its exact placement in your exact room using only your phone. If you want to manually EQ your Varro subwoofer, our free iOS and Android App offers an industry leading 8-band parametric eq.


All of the Varro Subwoofers employ the AK7735 Dual 28-Bit DSP with a 147mHz master clock frequency to process all audio signals with high accuracy and minimum latency.
