Golden Ratio (GR) design follows the classical proportion for aesthetics and includes internal baffles to minimize standing waves. Speakers incorporate a custom co-axial driver from acclaimed Radian Audio, custom crossover and components selected for optimal performance. The cabinets have twin rear ports to deliver an open and transparent sound easily driven by low power tube amps. Designed and built by industry veteran Frank Fazzalari and improved over the years. A purchase of a Coherent speaker is an investment in Frank and a guarantee of personalized service and open sharing of his knowledge.
The standard Aluminum diaphragm and Mundorf capacitor can be upgraded to an exotic Beryllium diaphragm and ultra high end Mundorf EVO Silver-Gold-Oil capacitor. Matching stands are also available.
