Beyond Conventional Subwoofers

The Arke Audio Bass Enhancer is an alternative to a subwoofer and takes a fundamentally different approach to low-frequency reproduction. Rather than simply adding more bass (like a subwoofer may), it works harmoniously with your Arke speakers to address the specific acoustic challenges of your listening environment.

The Timing Advantage

Conventional subwoofers - particularly ported designs - typically exhibit group delay measurements of 20ms or higher in the lower frequencies. This temporal lag creates an audible disconnect between bass notes and the rest of the music, resulting in smeared transients and rhythmic incoherence.

The Arke Audio Kratos is an audiophile bass unit, and through its sealed design achieves extension to 20Hz while maintaining a remarkably low 10ms group delay at 30Hz, perfectly matching our Mikros and Solos speakers (5-10ms GD at 30-50Hz). The result? Bass that starts and stops with precision, maintaining perfect synchronization with your main speakers.

Technical Implementation

At the heart of the Arke Audio Bass Enhancer is a premium 10" Purifi Audio driver known for exceptional excursion capabilities and minimal distortion. This transducer operates in a critically-damped sealed enclosure powered by a robust 500W plate amplifier, delivering bass that's not just deep but remarkably agile and detailed.

Surprisingly Compact

Measuring just 350mm × 350mm × 380mm (H×W×D), the Arke Audio Bass Enhancer achieves performance typically associated with much larger systems. Despite reaching down to 20Hz, it fits discreetly into most living spaces without dominating your room aesthetics.

Intelligent Room Integration

Rather than applying broad low frequency boost, the Arke Audio Bass Enhancer - a subwoofer alternative - addresses your room's specific acoustic profile by supplementing frequencies only where room nulls occur. This targeted approach creates more linear bass response without exaggerating frequencies that already benefit from room gain.

The Sonic Result

Experience bass that sounds completely integrated with your music - precise, detailed, and properly timed. Bass notes maintain their natural attack, sustain, and decay characteristics, preserving the musicians' intended expression exactly as it should be heard.

Beautifully engineered sound
