Graham Audio SYSTEM3D

SYSTEM3D

Developed originally for the Royal Opera House, the SYSTEM3D offers the same neutrality and transparency as our BBC-licensed loudspeakers, but at much higher sound pressure levels. This is a system that is at home in the recording studio, or in a high end hi-fi setup in a large listening room. Extremely high levels of openess and delicacy are combined with an astonishing dynamic performance. Remarkably, this performance level is achieved using a conventional passive configuration, but one that is able to be used with amplifiers rated at up to 1000 watts per channel.

The system is built around a refined version of Volt's 3 inch midrange dome. A 34mm tweeter from SEAS takes over at 4kHz, while bass frequencies are handled by three high power 10" woofers. To provide complete flexibility, the SYSTEM3D will be available in different configurations - all using the same midrange and tweeter, but with differing bass configurations according to the sound levels required. As well as hard-wearing textured paint finishes suitable for professional use, the system is available with the same real-wood veneers used across the Graham Audio range.
