"THE FIFTEEN" 

Super Monitor & Floorstanding Loudspeaker

 

Modified  15” Radian Coaxial driver with crossover based on totally new design principles

 

As with all Coherent loudspeakers, the cabinet design follows the classical Golden Ratio proportions. As with the model TWELVE, The FIFTEEN speaker series also offers a choice of two aesthetic designs - a Super Monitor (GRA - Golden Ratio) or a Floorstander (MGRA - Modified Golden Ratio).

This series includes 2 models, covering 2 Performance Levels :

  • FIFTEEN Signature - MGRA Floorstander

  • FIFTEEN Reference - MGRA Floorstander

All speakers in the FIFTEEN Series incorporate a custom co-axial 15" driver from acclaimed Radian Audio, custom crossover and "Premium" components -- all carefully selected to deliver increasing levels of exquisite musicality, and this regardless of music genre !

The cabinets have twin rear ports to deliver an open and transparent sound easily driven by low power tube amps, and include a unique internal baffle structure to minimize standing waves.
