Hippo

Active Analog Subwoofer

HIPPO is an active, analog subwoofer designed to deliver deep, controlled low-frequency extension with speed, precision, and musical authority. Built around a passive radiator system, HIPPO achieves powerful sub-bass output without port noise, turbulence, or compression. Its fast transient response and accurate pitch definition make it an ideal partner for nearfield and midfield monitors. By maintaining phase coherence and low-mid clarity, HIPPO integrates seamlessly into professional monitoring environments. With a fully analog signal path and acoustically transparent protective grille, HIPPO delivers honest, fatigue-free low end you can trust for critical listening, mixing, and mastering decisions.

Deep Bass Without Compromise
HIPPO uses a passive radiator enclosure to deliver extended low-frequency response without the drawbacks of traditional ported designs. By eliminating turbulence and resonance, it produces clean, fast, and tightly controlled bass with excellent definition.

Designed for Seamless Integration
Engineered to pair naturally with nearfield and midfield monitors, HIPPO provides accurate sub-bass reinforcement that enhances scale and depth without overpowering the mix. The result is a balanced, coherent low end that translates reliably.

Fast Transients, Clear Pitch
The passive radiator design minimizes phase anomalies in the critical low-mid region, preserving transient detail and pitch accuracy. This makes HIPPO especially effective for critical listening and precise mix decisions.

Pure Analog Signal Path
HIPPO follows a fully analog architecture, maintaining the natural character of the source without digital artifacts. The sound remains rich, musical, and direct, revealing subtle dynamics and tonal nuance.

Transparent Protection
An acoustically transparent grille provides physical protection while staying sonically invisible. Its high open-area perforation ensures clarity, balance, and transient response remain unchanged.

Refined Aesthetics
Available in two premium colors, HIPPO features a soft-touch, silky matte finish that complements both modern studios and refined home setups.
