ELAC’s Varro Subwoofer Collection Is Rather Bottom Heavy

Starting at $650 USD, the new Elac Varro Series Subwoofers offer something for everyone but which one makes the most sense for you? We break it down.

ELAC VARRO Subwoofer Line 2023

ELAC, a leading manufacturer of high-performance speakers and electronic components, is offering up its new Varro subwoofer lineup

The new Varro lineup consists of three distinct series that includes seven new models:

  • Premium: PS250-BK (10-inches), PS350-BK (12-inches), PS500-BK (15-inches)
  • Reference: RS500-SB (10-inches), RS700-SB(12-inches)
  • Dual Reference: DS1000-GB (10-inches), DS1200-GB (12-inches)

Common Features

Here are features included in all Varro Series Subwoofers unless otherwise stated. 

BASH Amplifiers: BASH amps are powerful and efficient and allow for maximum voltage swings, providing all the power that is needed and additional dynamic power throughout the entire operating range of the woofers. 

MDF Cabinets with Internal Bracing: To reduce cabinet flex and reduce cabinet resonances, all Varro subwoofers incorporate MDF cabinets ranging from 30mm (1-3/16 inches) on the Premium series increasing to 36mm (1-7/16 inches) on the Dual Reference Series. Additional internal cross-bracing is included which is designed to further reduce resonances that may negatively impact tonal balance. 

Custom Designed Drivers/Large Diameter Voice Coils: Custom woofer drivers were designed for each Varro Series subwoofer to match the power output of its paired amplifier. To assist in this task, tbe drivers have large diameter voice coils (2 inches on the Premium models and 2.5 inches on the Reference and Dual Reference Series models) to accommodate higher power and the heat generated by the motor structure. 

DSP (Digital Signal Processing): The Varro subwoofers incorporate dual 28-Bit DSPs with a 147mHz master clock frequency. This supports audio signal processing with high accuracy and minimum latency. 

Advanced APP Control: Doing away with traditional analog controls, our new Premium series subwoofers incorporate an advanced digital control system. The ELAC Sub Control 3.0 app (iOS, Android) can provide complete control of one or more compatible subwoofers as the need arises. 

ELAC Auto EQ Room Correction

Auto Room EQ: To better assist in finding the best location to place a subwoofer in a room is not always easy. Using the Elac Sub Control 3.0 app and a smartphone microphone, users can optimize room EQ automatically, allowing greater flexibility in placement without sacrificing performance.

Included Accessories: Grille, AC Power Cord, Spikes

Reference/Dual Reference Series Additional Features

Aluminum Sandwich Woofer: The Varro Reference and Dual Reference subwoofers use high excursion woofers that include a rigid and lightweight aluminum cone sandwiched with a treated paper cone using a special gluing process. According to Elac, this construction retains the transient capabilities of cellulose cones with the rigidity of aluminum. The drivers are also designed to provide extra-long cone throw that can more easily handle both high signal levels and low bass.

HEX Surrounds: Elac claims that its HEX surround geometry allows for a very linear relationship between applied force and resulting displacement in both directions. This ensures faithful reproduction of the recorded signal with low distortion even at high playback volumes.

Wireless Connectivity: Both the Reference and Dual Reference Series subwoofers have a built-in Elac AirX2 wireless receiver. To use wireless connectivity, connect an optional AirX2 Wireless transmitter to an AV receiver, and wirelessly transmit information to the subwoofer. 

Tip: Listeners can utilize up to 3 Reference or Dual Reference subwoofers simultaneously using the AirX2 wireless system.

Advanced Connectivity: The Reference Series adds speaker-level inputs for use with receivers and integrated amplifiers without a  dedicated subwoofer output. The Dual Reference Series adds balanced XLR inputs for compatibility with premium audiophile and professional audio gear. 

Custom Install Ready: Both the Reference and the Dual Reference Series subwoofers feature an ethernet port for connection to 3rd party control systems such as Control4, Savant, Crestron, and RTI.
