"5 days to conceive - 5 years to perfect"
The Serhan+Swift team searched long and hard and tested many designs over a 5 year R&D period before settling on the final design ingredients.
One of the most crucial aspects of any loudspeaker is the driver selection. In a search for the best performing and lowest distortion drive units, the renowned Scan-speak loudspeakers of Denmark -premium Revelator series - was finally select- ed for both the bass-midrange driver and ring-radiator tweeter. These drivers are also found in much more expensive speakers from high-end companies such as Wilson Audio, Sonus Faber and others—some costing well over $50K. Their use in a speaker at this price point is unheard of - pun intended!
After extensive experimentation with low and high-order crossover configurations, a high-order crossover was ultimately chosen allowing for steeper slopes, to keep the drive units in their respective “power bands” and minimise out of band distortion. Whilst this increases component cost dramatically the audible benefits are very obvious.
Nothing is left to chance - only the best components are used including Solen capacitors and even these are hand value trimmed and pair-matched. Air-core inductors are supplied over-wound and then custom trimmed exactly to the desired value. This time consuming attention to detail ensures that every single mu2 SE provides the same exacting performance.
The mu2 SE is clearly not a production line speaker - every unit is meticulously hand crafted. The mu2 SE further benefits from carefully considered use of super high-end Auricap XO capacitors, carefully selected after 1000’s of man-hours of critical listening and measurement. However, components are not selected simply on the basis of brand or reputation - synergy is key. They have to perfectly suit the application.
Bass and treble crossovers are kept separate and hand wired, point to point, then silver soldered on 5mm thick high den- sity substrates. Proprietary micro vibration control is also applied here. These measures reduce unwanted noise and dis- tortion even further.
The Cardas brand terminals are high purity copper with rhodium plating. Expensive, but audibly superior, reliable, and long lasting. (Nothing has been overlooked. Attention to detail means you hear the detail.
