Product details
The Telegrapher HIPPO is an active analogue studio subwoofer designed to extend the low-frequency performance of nearfield and midfield studio monitoring systems. Built for music production, mixing, and critical listening, it delivers deep, controlled bass with fast transient response and clear pitch definition. Its analogue signal path and passive-radiator enclosure are engineered to preserve the natural dynamics of the audio while reducing unwanted port noise.
The HIPPO features a 10-inch low-frequency driver supported by two side-firing passive radiators. This design extends bass response while maintaining control and minimising turbulence associated with conventional bass-reflex ports. A dedicated 250 W Class D amplifier powers the subwoofer, providing substantial low-frequency output for professional monitoring applications.
Its adjustable analogue crossover allows users to select a low-pass frequency between 30 Hz and 300 Hz, helping integrate the subwoofer with a range of studio monitors. Adjustable phase control, polarity switching, and balanced XLR inputs and through outputs provide additional flexibility when configuring a monitoring system. A protective grille, automatic standby, and LED-based protection indicators support practical everyday studio use.
