"THE TWELVE"

Super Monitor & Floorstanding Loudspeaker

 

 

Modified  12” 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. This speaker series however offers a choice of two aesthetic designs - a Super Monitor (GRA - Golden Ratio) or a Floorstander (MGRA - Modified Golden Ratio).

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.

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
