JL Audio's exclusive D.A.R.O. technology uses a powerful on-board DSP to automatically optimize the subwoofer's in-room frequency response. This leads to a superb listening experience, no matter where the subwoofer is placed.
In typical listening spaces, subwoofer and listener placement have a profound effect on the accuracy of low-frequency reproduction. While we always recommend that you place your subwoofers in good-sounding locations, we know that these often can be impractical locations. In the real world, subwoofer placement almost always involves a compromise between sonic performance, practicality and aesthetics.
To face this dilemma head on, JL Audio subwoofer systems incorporate a clever piece of technology called Digital Automatic Room Optimization (D.A.R.O.). The D.A.R.O. system self-generates a series of calibration tones, measures the frequency response at the listening position, and automatically configures an 18-band, 1/6 octave equalizer for a flat end-result. The system effectively allows for smooth, well-balanced sub-bass from a variety of locations that would have been less than ideal without D.A.R.O.
1. Connect the calibration microphone to the front panel of the subwoofer.
2. Press the calibrate button on the front panel of the subwoofer.
3. Hold the microphone at the primary listening position for about a minute.
4. A few minutes later, you have completed this one-time setup routine.
You won't need a computer, spreadsheets or complex measurement equipment, and you won't need to navigate and manipulate complicated interfaces… D.A.R.O. is a fine example of technology in the service of man, if there ever was one.
