Know before you buy
The tribrid system uses three distinct driver technologies—a dynamic driver for bass, balanced armatures for mids, and electrostatic drivers for treble—to handle specific frequency ranges. This allows the Oracle MKII to deliver deep sub-bass, accurate vocals, and extended, airy highs simultaneously without the distortion often found in single-driver setups.
Yes, the Oracle MKII features improved ergonomics and is crafted from medical-grade UV resin to ensure a comfortable, secure fit. The lightweight design is specifically intended for extended use in both professional studio environments and casual listening.
While the Oracle MKII is designed to be efficient, its high-fidelity nature benefits from a clean signal source. Using a dedicated DAC or amplifier will help you get the most out of the electrostatic drivers and ensure the full frequency range is accurately reproduced.
The modular cable allows you to switch between 3.5mm, 4.4mm, and 2.5mm plugs without needing to replace the entire cable. This makes the monitors compatible with a wide range of devices, from standard smartphones and laptops to professional balanced audio equipment.
The Oracle MKII is tuned for studio-style neutrality, meaning it aims to reproduce audio as accurately as possible. It provides a clean, detailed sound with a dedicated sub-bass boost for depth and an extended treble response that adds clarity and 'air' to your music.
Absolutely. Because the Oracle MKII is tuned to be monitor-neutral and faithful to the original recording, it is an excellent tool for critical listening, mixing, and mastering tasks where accuracy is essential.
