Kanto ORA4

Professional sound and power in a compact form factor

• Class D bi-amplification with separate drivers for woofer and tweeter.
• 140 W peak / 70 W RMS, perfect for desktop, studio or near-field listening.
• Modern connectivity with USB-C, Bluetooth® 5.0 and RCA inputs.
• Auto crossover at 80 Hz for seamless integration with subwoofer.
• Flat, accurate response from 60 Hz - 22 kHz.
• Compact design with mounting options and magnetised woofers.

Bi-amping and DSP for maximum clarity

Each driver receives dedicated power thanks to bi-amplified Class D amplification. Internal digital processing (DSP) fine-tunes crossovers and reduces distortion, delivering a more defined, balanced and cleaner sound, ideal for production, mixing or critical listening.

Automatic subwoofer integration

When a subwoofer is connected, the ORA4s automatically activate a high-pass filter on the woofers. This frees up the low frequencies, improving the clarity of the mids and highs, and allowing the subwoofer to handle the bass only. The result is a more articulate and controlled sound across the entire spectrum.

Versatile connectivity for any environment

The ORA4s offer three input types to accommodate both digital and analogue configurations:

• USB-C (24-bit/96 kHz) for direct connection to computers.
• Bluetooth® 5.0 for high-quality wireless streaming.
• RCA line-in for players, pre-amped turntables or other traditional equipment.
  This allows for easy source switching without the need for additional adapters.

High performance in a small size

Despite their compact form factor, the ORA4s integrate 4" bass-reflex aluminium woofers, achieving deep, defined bass without taking up a lot of space. They are an excellent choice for desktops, small studios or minimalist setups that don't want to sacrifice power or quality.
