- What's New?

With its smart new high quality matt black finish or matt white finishes, the mu2 Mk II is much more than just a facelift, it's a totally new loudspeaker. All elements - cabinet, woofer, tweeter, crossover - have been carefully re-examined and significantly improved, even where many thought no further improvement was possible. Lessons learned from the original mu2 Special Edition (as well as our ongoing research into the effects of vibration on all components) - have been expanded upon, and now been applied to the mu2 Mk II. Constrained layer damping material has been custom manufactured for the mu2 by Les Davis Audio.

While the woofer and tweeter may look the same as the previous model, both have been improved with even flatter response, smoother roll off, and lower distortion. Enhancements to the crossover take full advantage of the above.

With 1000’s more hours of listening tests and measurements, the cross-over region and on-axis to off-axis transition are even more seamless and even more difficult to detect (always outstanding features of the original design).

The new multi-layer cabinet construction now employs additional layers of differing materials, carefully chosen for composition and thickness, for even further reduction in cabinet noise (vibration), energy storage and coloration. Bracing has been further strengthened.

Of course, the other attributes for which the mu2 is renowned have all been retained.

 

Design - "5 days to conceive - 5 years to perfect"

With 5 years of R&D and component testing, Serhan Swift found the optimum drivers to be a bass-midrange woofer and ring-radiator tweeter belonging to the premium. Revelator series manufactured by renowned Scan-speak of Denmark. 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.

Bass and treble crossovers are kept separate and hand wired, point to point, then silver soldered on 5mm thick high density substrates. Micro vibration control is also applied here. These measures reduce unwanted noise and distortion 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 every detail).

Serhan Swift consider their products a long-term investment. Each pair of mu2 MKII’s take 3 days from start to finish under the watchful eyes of Chief Loudspeaker Designer Brad Serhan and Engineering Director Morris Swift. Brad performs final testing and then he and Morris proudly sign each unit.
