DYNAMIC CONTENDER.

The SUB 2070 is in principle identical to the larger SUB 2090, but utilizes smaller drivers and a smaller enclosure for more discreet room placement. The push-push/pull-pull principle is applied to two 250 mm woofers driven by a powerful BASH amplifier, able to deliver 600 Watts and huge dynamic range. It incorporates the same powerful app that makes output and room equalization a snap.

*600 Watts Max Power

**A Bluetooth 4.0 low-energy Android or IOS device is required to set up and operate this subwoofer.

BRAINS AND BRAWN.

How smart can a subwoofer be? Thanks to the ELAC SubEQ app and the Advanced Bluetooth® control interface, listeners can simply pair an iPhone®, iPad® or Android® device with the new ELAC SUB 2090, 2070 and 2050 subwoofers and adjust the sound to their preferences. Intuitive, comprehensive and downloadable, free of charge, this clever app means there are no complicated network connections, as the subwoofer and mobile device communicate directly via BLE (Bluetooth® Low Energy).

Doing away with traditional analog controls means no fiddly adjustments at the rear of the subwoofer. Four preset modes can be selected at the touch of a finger: Normal, Music, Cinema, and Night. Those who want to explore the possibilities of the app-control system further will discover genuine pro-audio options such as a parametric equalizer, a low-pass filter, and individual settings for power-saving auto-on function. The the most exciting option is the calibration function, which uses the microphone on your smart-phone to listen to the volume, frequency response and sound reflections in the room before automatically optimizing the sound of your ELAC subwoofer.

The new ELAC subwoofers can be connected directly using loudspeaker cables (left, center, right) or stereo RCA cables. With the SUB 2090, symmetrical wiring can be also used. And if you prefer to dispense with wires altogether, the new high-performance subwoofers are equipped with an ELAC Wireless Interface for wireless music transmission.

The challenge for powered subwoofers and their amplifiers

Audio quality and power efficiency have long been at odds when it comes to amplifier design. Traditional Class AB amplifiers, which account for about 90 percent of all amplifiers made, are capable of producing prodigious power and excellent sound, but do so at the expense of efficiency. In fact, up to 50 percent of these amplifiers’ energy is wasted, dissipated as heat. Heat becomes an added liability when such amplifiers, in the case of powered subwoofers, are enclosed in a speaker cabinet. Class D switching amplifiers, on the other hand, run cool and occupy relatively little space. Compact, lightweight and efficient, they are a sensible choice for the latest applications, especially when used for powering subwoofers. Typically, however, the sound quality achieved by typical Class D designs has not been suitable for the best audio applications, but new technology has improved these designs to compete with the best of traditional amplifier topologies.

Enter BASH® amplification

BASH (Bridged Amplifier Switching Hybrid) amplifiers represent a “best of both worlds” solution for subwoofer amplification, combining the sound quality of Class AB with the efficiency of Class D amplifiers. While a Class AB amp uses fixed supply voltage regardless of input signal, BASH uses a modulated switched mode power supply that tracks the input signal, supplying only the necessary voltage to the Class AB amp as needed. The latest BASH technology has gone through three core evolutions and is further refined in these latest ELAC Debut subwoofers.

Push-push/Pull-pull configuration

The SUB 2090 and SUB 2070 deliver perfect, clean and distortion-free reproduction of low frequencies, employing a push-push/pull-pull arrangement of the two woofers that eliminates vibrations and mechanical resonances. Positioned opposite to one another but electrically driven in parallel, the acoustical output of both drivers is added up, but the mechanical forces cancel one other. Hence, no mechanical distortion remains to compromise the purity of the bass spectrum.

 

Advanced Bluetooth® control

SUB 2090, SUB 2070 and SUB 2050 subwoofers incorporate an advanced, digital control system. Analog rotary potentiometers and switches have been replaced by a digital signal processor (DSP), which allows users to adjust the subwoofer conveniently and accurately. All parameters, such as volume, cutoff frequency, phase etc., as well as the automatic calibration function, can be conveniently adjusted with the help of the ELAC app.

Auto power On/Off

Debut subwoofers will detect when audio is being sent to the unit and power the unit on. Also, to conserve energy, the subwoofer will power off after a long period of inactivity.
