Know before you buy
D.A.R.O. uses a calibrated microphone to analyze your room's acoustics and automatically adjust the subwoofer's output to correct for peaks and dips. This ensures a flatter, more accurate frequency response tailored specifically to your listening environment.
Yes, the SA-600W is designed with versatile mounting options and is rack-mountable, making it a clean fit for dedicated home theater or audio equipment racks.
Yes, it features a dedicated JLink™ port that allows for optional wireless connectivity, giving you more flexibility in where you place the subwoofer in your room.
The amplifier is highly versatile, offering both line-level (RCA) inputs for standard pre-amp connections and high-level inputs if you need to connect directly from your receiver's speaker outputs.
The parametric EQ allows you to manually target and adjust specific frequency ranges. This is useful for fine-tuning the bass response beyond the automatic optimization to suit your personal listening preferences.
The SA-600W is optimized for a 3-ohm load and is designed specifically to power JL Audio subwoofer systems. While it provides 600 watts of power, it is best paired with compatible passive subwoofers that match its impedance requirements.
