Know before you buy
Yes. While it is designed to complement ATC monitors, its flexible controls—including variable phase, gain, and multiple low-pass filter settings—allow it to be integrated with a wide range of active loudspeaker systems.
Absolutely. The SCS70 Pro is specifically engineered for multi-channel and immersive audio environments, and its ability to daisy-chain multiple units makes it an excellent choice for complex surround configurations.
The sealed-box, or infinite baffle, design provides superior driver control and a more natural, accurate low-frequency roll-off. This results in tighter, more precise bass reproduction that is less prone to the 'boominess' often associated with ported designs.
The SCS70 Pro supports an optional footswitch, which allows you to remotely mute the subwoofer. This is particularly useful if you need to quickly toggle the sub off during a session without reaching behind the unit.
Yes, the 300W Class AB amplifier features a built-in limiter to prevent distortion and includes fault monitoring for temperature and DC offset. Front-panel LEDs provide clear status indicators for power, limiting, and muting.
Yes, you can set the low-pass filter to 'Off,' which extends the frequency response up to 320Hz. This allows you to use external DSP or dedicated monitor controllers for more advanced bass management.
