The function of the Master Reference Subwoofer is to reproduce, with unprecedented authority and fidelity, the lowest reaches of the audio spectrum, thereby extending the low frequency capabilities of even the finest music and home theater systems.

The Krell Master Reference Subwoofer sets a new standard in powered subwoofer design. At the heart of the Master Reference Subwoofer is its proprietary interface. This programmable electronic crossover provides unparalleled matching for subwoofer and system components and allows seamless integration with any loudspeaker configuration. Additional innovative technologies such as Active Motion Control are specifically designed to unleash the full power of the built-in Krell amplifier while assuring that the special characteristics of low frequency sound are meticulously reproduced. Innovative technology teamed with Krell’s outstanding core technology ensure maximum power, precision, and performance in the low frequency range.

Innovative Subwoofer Technology and Design

Programmable Electronic Crossover

The programmable electronic crossover is a design tour de force. It seamlessly matches the Master Reference Subwoofer to the characteristics of your system. You can select and adjust high-pass and low-pass filter profiles and parameters. Three filter profiles with unique response characteristics integrate the Master Reference Subwoofer with any loudspeaker and listening setup. Each filter profile includes parameters for frequency, slope, and level, allowing you to further fine-tune the subwoofer to your system. These adjustments are easy to select using the Master Reference Subwoofer’s step-by-step menu and remote control.

Krell Active Motion Control

The traditional approach to subwoofer design is to incorporate a standard servo circuit that uses feedback to control the drivers at higher output levels. Doing so effectively controls the drivers, but it can also dampen the musical dynamics, losing the visceral impact of the low frequency range.

At the heart of the Master Reference Subwoofer is a custom-engineered driver, designed to handle the demands of high-powered audio. With a large diaphragm and a powerful motor system, this driver can reproduce lower frequencies with remarkable accuracy. The subwoofer utilizes a sophisticated suspension system that allows for greater travel while maintaining linearity, resulting in an impressive dynamic range. This means that whether you're listening to the subtle nuances of a classical piece or the thunderous explosions of an action movie, the Master Reference Subwoofer can handle it all with finesse.

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.

In summary, the Krell Industries Master Reference Subwoofer showcases the company's commitment to audio excellence through its unmatched construction, innovative driver technology, and advanced digital processing capabilities.
