Krell's proprietary technologies further enhance the performance of the Master Reference Subwoofer. The subwoofer features advanced digital signal processing (DSP) that allows for precise tuning and customization of the audio output. This ensures that the subwoofer can adapt to different room acoustics and individual preferences, resulting in optimal sound quality in any environment. Moreover, the Room EQ feature automatically analyzes the listening space and adjusts the output accordingly, providing an incredible level of personalization.

Connectivity options on the Master Reference Subwoofer are diverse and versatile, including XLR and RCA inputs, making it compatible with a wide range of audio systems. The intuitive interface allows users to easily navigate through various settings, making setup and adjustment a breeze.
