Telegrapher Hippo Active Analog Subwoofer for Studio Monitoring
By HiFi Editorial4 March 2026
Key Highlights
Telegrapher introduces Hippo, an active analog studio subwoofer designed to complement near- and midfield monitors with precise, controlled sub-bass monitoring.
The design pairs a 10-inch woofer with side passive radiators, delivering extended, detailed low frequencies that remain articulate and easy to control.
A 250 W Class D amplifier provides ample studio output, achieving up to 102 dB SPL without sacrificing accuracy.
Telegrapher positions Hippo firmly in the “tool, not toy” category, and the engineering choices underline that intent. The decision to stay fully analog in the signal path, including the crossover section, will resonate with users wary of latency and phase artifacts often introduced by DSP-heavy designs. An analog crossover with a wide adjustment range suggests flexibility for integrating with a broad spectrum of monitors, from compact two-ways that need early handoff to larger systems where the sub only fills the bottom octave. The unusually wide phase control range also hints at practical placement freedom, especially in imperfect rooms where boundary interactions dominate the lowest registers.
