The Electra range stems directly from the extraordinary array of Utopia speakers. They possess the same W membrane glass-glass technology ’ hand made by a team of artisans who spend at least 30 minutes on each cone, as well as the Focus Time system, which allows the listener to orient the axes of the speakers towards themselves, using the tweeter as the axis. This system allows the perfect focussing of mid to high range sources as well as punctual sources and perfect phasing.
The Electras are true top line speakers and are destined to a demanding public of sound buffs who will tend to associate them with powerful electronics.

The Electra SR 30 are Bass Reflex Surround speakers of the Dipolar variety, with four voice cones ’ two 13 cm W cones and two Tioxide tweeters identical to those of the 920, 915 and 905. They were originally designed to be placed laterally, directed towards the listener.
