Telegrapher HIPPO – 10″ Active Analog Subwoofer – Trooper White

OVERVIEW

The Telegrapher HIPPO is a 10-inch active, analog subwoofer built around a passive radiator system to deliver deep, controlled low-frequency extension with speed and precision. The passive radiator enables high output and extended bass without port turbulence, chuffing, or compression, keeping the low end clean and tightly controlled.

Designed to integrate seamlessly with nearfield and midfield monitors, HIPPO provides accurate sub-bass reproduction with excellent transient response and pitch definition.

The passive radiator enclosure allows HIPPO to extend low-frequency response while maintaining control and accuracy. By eliminating port turbulence and resonance, the PR design delivers fast, well-defined bass with reduced phase anomalies in the critical low-mid region. The result is a coherent, balanced presentation that preserves transient detail and spatial accuracy, making it reliable for critical listening and precise mix decisions.

HIPPO follows a fully analog signal path, preserving the natural character of the source without colouration or processing artifacts. This approach delivers a sound that is rich, musical, and direct, allowing subtle details, dynamics, and tonal balance to translate clearly and honestly.

TRANSPARENT GRILLE

Acoustically, the grille is designed to stay out of the way. The perforation pattern has a high open area, allowing sound to pass through freely without being filtered, so the speaker’s natural balance, clarity, and transient response remain intact.

The grille does its job of protection without imposing a sonic character of its own, keeping the sound open, direct, and unchanged.

HIPPO is currently available in two beautiful colours, featuring a premium, soft-touch, silky matte finish – Jaipur Orange and Trooper White.
