Exclusive Strat F1 and F2 Planars
It’s in the execution of art and science. The proprietary Strat F series planar puts other planars and ribbons to shame.
How dare we claim that the Strat F series planar is so great? Well, the Strat F series planar uses the strongest neodymium magnets and the most rigid structure imaginable. And when you put a physicist who is a musician in charge of creating the F1 there are virtually no compromises.
And confidentially, there are a few secrets that add to the mix. Like patented internal damping techniques and diaphragm tensioning processes.
This results in drivers having less than a .5db difference in production. So in the end, the Strat F series planar is highly efficient, has wide dynamic range, extended frequency response, consistent quality and is virtually distortion free.
The NEW Strat F118
Evoke has developed an all-new planar tweeter to match the speed and tambor of the Strat F1 mid-planar. The two drivers blend seamlessly with a carefully selected crossover that creates the best imaging possible. In addition, having both drivers mounted on the same faceplate allows for optimum placement to each other for exceptional time alignment.
One of the key goals of the new tweeter was to eliminate the transformer of the ribbon tweeter. The more direct current path allows for faster transient response and dynamic headroom without the coloration of a transformer.
RM Series Woofers
Finding a woofer for EVOKE loudspeakers presented an even greater challenge. The driver had to be specifically designed to match the Strat F series planar. Variations were considered including size, cabinet alignment and different Thiele-Small parameters. In the end the RM series proved a match to the Strat F series planars.
It features a low mass cone and extends the low end to the point where you may feel a subwoofer is not needed [except for home theater and very high output levels]. The heavily cast frame stabilizes extended linear cone excursion. And the phase plug breaks up the anomalies inherent to a cone driver to approach the performance of a flat planar.
T-Phase System Integration
Time and Phase. These may be two of the most contentious words in the loudspeaker business – One reason being all the misinformation and opinions that have been propagated by consumers and speaker companies alike.
Let’s consider this daunting task. Time and phase are affected by the baffle and driver placement. Each driver has its own phase components that change with frequency. Crossover components introduce their own phase and delay issues. Then imagine three drivers interacting with each other!
That should give you an idea of the complexity presented by time and phase. Then add in things a loudspeaker can’t control – the position of your speakers, where you sit and the acoustics of your room.
So what does EVOKE do? We takes an overall approach called T-Phase System Integration. By considering all factors together our loudspeakers achieves excellent results in both time alignment and phase coherence. The result is fast attack time for wide dynamics and coherent phase for spacial imaging.
Distortion and Dynamic Range
EVOKE design and engineering have brought together high performance Loudspeakers. The end result comes together to deliver a musical performance that you can hear. They have incredible dynamic range revealing the subtle harmonics of a recording as well as its dynamic crescendos.
How is that possible? Most other speakers lack dynamics, are fatiguing and just sound loud – that’s because in reality you are listening to distortion. EVOKE loudspeakers sounds better because of the lack of distortion. As a result you may not realize just how loud you are playing them!
