"THE EIGHTEEN" - NEW MODEL !
Flagship Floorstanding Loudspeaker
Modified 18” Radian Coaxial driver with crossover based on totally new design principles

This series includes 2 models, covering 2 Performance Levels :
-
EIGHTEEN Signature - FS-MGRA Floorstander

EIGHTEEN Reference - FS-MGRA Floorstander
The all new EIGHTEEN Series incorporate a custom co-axial Neodymium 18" driver from acclaimed Radian Audio.
This is a very exciting development as it probably is a "first" in the world of Concentric High Efficiency / Sensitivity Loudspeakers :

The Design
The focus of Frank's research is to :
Design and build an accessibly priced speaker that would most realistically deliver the micro-dynamics, vividness, dimensionality and excitement of live music
After numerous prototypes, extensive listening tests and continuous design refinements, Frank determined that the best way to achieve the desired objectives would be through a high sensitivity and high quality full range co-axial driver.
The basic requirements were ultimately fulfilled by the American-made Radian coaxial drivers
However, this was only the the starting point :
-
The Radian driver undergoes extensive modifications by Coherent Audio
-
The modified driver and is then matched to a special crossover designed and built by Coherent
-
This crossover is based on totally new design principles and incorporates special coils which are built by Coherent Audio
-
Finally, and very importantly, each model of coaxial driver is matched to a Coherent designed and hand built cabinet that incorporates unique design features to allow the modified coaxial units to perform at their maximum capability
The end result is an outstanding and very exciting new range of high efficiency speakers offering :
Extremely accessible pricing for the performance
and hand-built quality being offered
