Coherent's exciting range of super high efficiency loudspeakers are designed and hand-built by Frank Fazzalari in Stoney Creek,
Ontario. Frank Fazzalari has been in the speaker building business for years, manufacturing enclosures for many well known Canadian companies. Around 2007, he decided to create his own line of loudspeakers. His first was the Model 6, followed by the Model 7 and Model 8. During that time, various custom
commissions and specialty model speakers were also produced.
In addition to building speakers, the last five years has seen extensive research conducted by Coherent Audio. The focus of the research was to design and build an affordable speaker that would most realistically deliver the microdynamics, 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 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. and is matched to a special crossover designed and built by Coherent. The crossover is based on totally new design principles and incorporates special coils which are also built by Coherent. 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 an outstanding and very exciting new range of high efficiency speakers, with extremely reasonable pricing for the performance and hand built quality being offered. As a result, Coherent speakers have been garnering more and more praise, from reviewers, showgoers and owners.
In the core lineup are three models, which correspond to the three sizes of coaxial drivers employed (10 inch, 12 inch and 15 inch ). All models are 8-Ohm designs and range in efficiency from 94 to 98 dB's. These speakers play beautifully with low power
tube amps in particular, and at last fill a long time void in the reasonably-priced and reasonably-sized high efficiency loudspeaker category. Since all speakers are hand-built, the customer can select from the options and veneers of their choice.
