Our take on the ELAC Debut S12EQ by Crutchfield's Kramer Crane
Use your smartphone to calibrate your sub
You won't find any knobs or switches here! Instead, use ELAC's SUB Control app for easy touchscreen setup and control via Bluetooth.
Once I saw and heard ELAC's new S12EQ, I knew it was something special. Not only does its 12" high-excursion woofer and 500-watt amplifier deliver heart-pounding bass that brings movies alive, but it also sports a new Bluetooth calibration feature that makes it easier than ever to get bass that's precisely dialed in for your room.
Sit back, relax, and let the sub do the work
The S12EQ uses your smartphone's microphone along with sophisticated on-board software to deliver the most accurate bass possible. No longer will you have to reach back behind your subwoofer to tinker with knobs and switches. Simply download the ELAC SUB Control app and let its powerful processing customize the subwoofer's settings for your room, wirelessly via Bluetooth.
Calibration made easy
The magic behind the S12EQ lies in how you set it up and control it. Everything is done from your device's touchscreen. The SUB Control app uses Bluetooth Low Energy, a wireless connection between your device and your sub that requires no pairing and no passcode.
The calibration process begins by capturing a near-field measurement of the subwoofer's bass output. Simply hold your phone or tablet within one foot of the sub and press "Analyze." The app then records what's coming out of the subwoofer, capturing sound before it's affected by its interaction with the room's reflective surfaces and other sound-muddying anomalies.
Then you'll do the same measuring process from your favorite listening position. The SUB Control software compares the first measurement against the second, then expertly smooths out the EQ curve, delivering crisp, accurate bass to your ears. Level control and other audio adjustments are made through the app. You can also make manual changes to the calibration settings as well.
A legendary speaker designer strikes again
Andrew Jones made a name for himself designing phenomenal high-end speakers across the industry. Lately, he's turned his attention toward creating speakers that offer excellent performance at very affordable prices. The Debut S12EQ subwoofer is his latest triumph. It makes a perfect match in a surround sound setup with the entire ELAC Debut line, all of which were designed by Jones.

Elac SUB Control App: The Elac Debut S12EQ powered subwoofer does away with traditional analog controls. Instead, the powered sub incorporates Elac's advanced digital signal processing (DSP) that is controlled from the Elac SUB Control app on your Apple (iOS 7.0+) or Android (OS 4.3+) device, wirelessly over Bluetooth 4.0. From the app on your compatible smartphone or tablet device, you can control the Auto EQ, Parametric EQ, Crossover, Phase, Delay, Volume, & Sound Presets. You will need to pair your compatible Apple iOS or Android device with the Elac powered sub before using the app.
- Auto EQ: The Elac Debut S12EQ powered sub and the Elac SUB Control app are equipped with an easy-to-use and highly sophisticated Auto EQ function to automatically calibrate the EQ curve of the powered sub based on the room environment. Using the built-in microphone of your Apple iOS or Android device, the app calculates the room environment, room frequency response, and the sound reproduction of the sub. Auto room calibration is performed in two steps - first, your smartphone's microphone is placed directly in front of the powered sub for measurement; second, your smartphone is moved to your main listening position for measurement. The app will then calibrate the subwoofer based on these two measurement locations and provide visual parameters of the measured room, along with the automatically calculated EQ curve.
- Parametric EQ: You can also choose to set the powered subwoofer's EQ curve manually by adjusting the SUB Control app's parametric EQ. The parametric equalizer gives you the ability to adjust the audio output (within the subwoofer's range) to your preference. The app will let you choose and adjust the center frequency, bandwidth, and gain.
- Low Pass Crossover: The app on your Apple iOS or Android device lets you setup the powered subwoofer's variable low-pass crossover from 40Hz to 150Hz to blend the bass output of the powered sub with the rest of the speakers in your system. If you are using a home theater AV receiver with an LFE output, you will need to set the crossover frequency to "Max" or 150Hz.
- Phase: The Phase setting of the app ensures the bass signal reproduces by the powered subwoofer blends seamlessly with the rest of your speakers. When the powered sub and the rest of your speaker system are playing in Phase, bass reproduction sounds uniform.
- Delay: The Delay parameter of the app enables you to delay playback of the subwoofer's audio signal in comparison with the rest of your speaker system and your main listening position. The delay can be set to 1 msec (13") to 20 msec (21.5'). If you are using an AV receiver with an LFE output and its own auto calibration function, then the receiver will set the delay time internally, so the SUB Control's Delay parameter should be set to "minimum" or 0.
- Volume Level: The volume control of the Elac SUB Control app on your compatible Apple iOS or Android device allows you to sets the subwoofer's output level relative to the output of the other speakers in your system for a well-balanced sound. You also mute and un-mute the volume of the powered sub from the app.
- Sound Presets: From the SUB Control app on your smartphone or tablet, you can choose from 4 different sound preset modes to suit your application, need, or preference. Select Normal for most applications, select Music to add subtle emphasis to the low bass range, choose Cinema to slightly boost the bass frequencies around 50Hz, or choose Night to reduce the maximum dynamic range and volume for late night enjoyment.
Note: There are no physical controls on the front or back of this powered subwoofer. The Elac SUB Control app and a compatible Bluetooth 4.0 enabled Apple (iOS 7.0+) or Android (OS 4.3+) device is required for setup and operation of this powered sub.
500W BASH Tracking Amplifier: The Elac Debut S12EQ utilizes a BASH tracking amplifier rated at 500W RMS and 1,000W Peak. Unlike conventional amplifiers, BASH amplifiers track the input signal and adjust the available supply voltage to a traditional Class AB amplifier. This makes the amplifier incredibly efficient, but also provides the on-demand power needed for dynamic movies and music.
12" Custom Woofer & Passive Radiator: A custom front-firing, high-excursion 12" doped paper cone woofer provides the quality and quantity of bass that is fundamental to accurately reproducing today's demanding movie soundtracks and music. The Elac Debut S12EQ powered sub also employs a down-firing 12" passive radiator to improve the transient response and increases the efficiency of the system.
Braced MDF Cabinet: The cabinet is made of MDF (Medium Density Fiberboard) with an internal horizontal brace to strengthen and stiffen the cabinet, helping minimize unwanted vibrations that can discolor music or movie content. The MDF outer walls of the cabinet are covered with a textured vinyl black finish. There is a metal grill on the front to protect the front-firing woofer.
LFE/RCA Input: The Elac Debut S12EQ is fitted with a mono LFE/RCA input for connecting the powered subwoofer to your home theater AV receiver or integrated amplifier.
Auto Power On/Off: The Elac Debut series powered subwoofer will detect when an audio signal is being sent to the amplifier and will power on. Also, to conserve energy, the powered subwoofer will power off after 15 minutes of no audio signal and inactivity. On back of the powered subwoofer is a LED that will illuminate blue to indicate that the powered sub is turned on; there will be no illumination when the subwoofer is turned off or in standby mode.
Rubber or Spike Feet: The Elac Debut S12EQ powered sub features integrated rubber feet for safe placement on hardwood, laminate, vinyl, and tile floors. Four spike feet are also included for secure placement on carpeted flooring. The spikes screw into the bottom of the subwoofer's rubber feet and add approximately 0.875" of height to the powered sub.
Placement: Proper subwoofer placement can take some trial and error. In many cases, the best position for the powered sub is in the front corner of the room. If placing the subwoofer in the corner creates an abnormal amount of bass, you can try moving the subwoofer to one of the side walls near the front of the room.
Elac Debut Series: The Elac Debut series family of loudspeakers consists of two bookshelf speakers, two floorstanding speaker, a center-channel speaker, a Dolby Atmos enabled speaker, and two powered subs.
