Kanto Audio ORA 4

The Kanto Audio ORA 4 is a powered reference speaker featuring bi-amping, DSP tuning, subwoofer integration, and USB-C/Bluetooth 5.0 inputs for precise and dynamic sound.

Powered Reference Speakers

The ORA4 takes the legacy of the ORA to the next level, offering deeper bass extension and reference-level sound suitable for both studio and home use. With a design focused on near-flat response, it ensures accurate mixing and lifelike playback. Modern connectivity options such as USB-C and Bluetooth 5.0 make it easily adaptable to any workflow or listening scenario.

Compact – Full-Size Sound

Despite its small footprint, the ORA4 delivers the impression of much larger speakers thanks to a carefully engineered design that combines clarity and dynamic range. It provides professional, reference-quality sound in a compact enclosure, ideal for desktop setups, small spaces, or portable use.

DSP-Tuned

Carefully tuned DSP ensures studio-precision sound while also delivering an enjoyable listening experience for everyday use. The 4″ woofers of the ORA4 combine dynamic, rich bass with accuracy and impressive response.

Dual Amplification & Sub Integration

Each tweeter and woofer is powered by a separate Class D amplifier (bi-amping), avoiding wasted energy and maximizing performance. Additionally, the ORA4 automatically detects a connected subwoofer and applies a high-pass filter to the 4″ woofers, reducing distortion by handling only mids and highs, while the subwoofer manages the low frequencies.
