Serhan & Swift MU2 MKII Bookshelf Speaker Solid Timber Special Edition w/ upgraded crossover Pair



 Serhan Swift mu2 Mk Special Edition w/ upgraded crossover

Based in Sydney Australia, Serhan Swift is a formidable band of loudspeaker designers with 100 years of combined experience, and one simple focus: build loudspeakers that reproduce music in such a way that it transcends the unachievable: “realism”, “belief”, “put the band in the room”, "transport me there" - the holy grail...


Brad Serhan has been quietly working away behind the scenes on what are best described as a turbo-charged version of the Mu2 and we are delighted to have a pair on permanent demonstration, they certainly have upped the performance over the standard model, both models are going to run side by side.

The standard Mu2 cabinet is manufactured from 25mm high quality birch-ply as opposed to mdf, this is much better at damping and as a result it dramatically lowers the noise floor of the speaker.

The SE version uses the same style of birch ply cabinet but it is 19mm thick, the missing 6mm is made up by a solid New Guinea Rosewood cabinet, so it’s effectively a cabinet within a cabinet, the rosewood is hand oiled to show off its natural beauty. This type of design dramatically reduces unwanted cabinet radiation and distortion to such a low level that the amount of subtlety and nuance the SE can pull out of a recording is quite something.

The Mu2 SE uses the same ScanSpeak 1″ Ring Radiator Tweeter and the ScanSpeak 5”/15cm Revelator Bass/Mid driver as the original.

Serhan & Swift core values

– Reliability – Consistency – Longevity

– Value "the price is not the cost (of ownership)" – Secure investment

– Anti-obsolescence – Invisible technology – ease of use and installation

– Subtle, understated appearance

mu2 - what's in a name?

The Greek letter mu (which looks like a "u", but pronounced "mew") is used in science and engineering to mean "micro" or one millionth. Here it signifies a speaker that is deceptively small in size, considering its big sound and performance.

But it has come to mean more - an approach to design that considers every detail, even the microscopic. Serhan & Swift pay particular attention to how energy is dissipated, and keeping vibration to an absolute minimum, as not only do these result in extraneous sound output, but the effect on the various components, including those in the crossover network, causes distortion. Our discoveries are applied to cabinet materials and construction, and the use of mechanical isolators for mounting drivers and crossover components.

Serhan & Swift have come to refer to this discipline as "micro vibration engineering" or "muve"

mu2 MK II - Details

With its smart new high quality matt black finish, 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 - see above) have been expanded upon, and now been applied to the mu2 Mk II.

While the woofer and tweeter may look the same as the previous model, both have been improved with even flatter response, smoother rolloff, 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 mu2 Mk II takes detail and resolution to yet another level, as well as making the spatial preentation even more realistic. Soundstage and imaging are readily apparent, appropriate and precise in scale, and rock solid - they don't appear to change or move.

Additionally, the speaker truly disappears, with listeners in our showroom unable to tell which speakers are playing.

Of course, the other attributes for which the mu2 is renowned (see Design Brief, above) have all been retained.
