The Gran Sfera Horn Speaker System

backchamber



Gran Sfera horns are based on the Le Cleac'h expansion selected for its open sound, lack of coloration and spherical wave release. It allows nuance and dynamics of music with a natural quality. It does not sound like a typical horn system more like an electrostatic with macro dynamics. The system's four elements are:
Alto Horn:
250hz horn with Le Cleac'h expansion designed for Lowther A55 driver with open baffle rear wave release.

Basso Horn:
120hz horn with Le Cleac'h expansion, ported rear chamber and proprietary bass driver designed specifically for this application. Response to 28hz at 100db/1watt/1m.

Grand Stand:
Isolates drivers for maximum clarity and micro detail. Separates Final Passage from Basso cabinet to prevent microphony.

Final Passage Crossover:
Provides seemless integration of the Alto and Basso Horns with coherent phase and open dynamic through extensive design and component selection. It is very simple electronically, a product of evolution, a first order (a single capacitor and resister) for the Alto and the Basso uses a second order (one inductor, one capacitor) with a super high quality inductor (20lbs. of OFC copper) with low DCR to maintain excellent impulse response.


The Gran Sfera is a complete system for comprehensive reproduction of music with high efficiency.
