Asymmetrical Cabinet Design
Sound bouncing around inside a speaker cabinet can have a significant
effect on the sound that comes out. The biggest problem is standing
waves that commonly occur between parallel surfaces. Standing waves
can interfere with and color the speaker’s output, thus degrading sound
quality. The standard solution is acoustic insulation material inside the
cabinet, which does help, but it doesn’t address the underlying problem
of cabinet geometry. Yamaha has gone the extra mile in designing the
MSR250 and MSR400 cabinets, employing a unique configuration that
eliminates parallel interior surfaces and therefore the root cause of
standing waves. Acoustic insulation is also applied to effectively deaden
the space inside the enclosure. Elimination of unwanted sound inside the
cabinet means that optimum sound can be delivered to where it counts
the most: your audience.

Ferrofluid Cooling
Any technology that involves power also involves heat, and this can result
in compromised performance if heat generation is not effectively
controlled. The current driving a speaker generates heat in the voice coil
that, in extreme cases, can cause the speaker to burn out. But even if the
speaker doesn’t actually burn out, that heat still results in inefficiency and
non-linearity that degrade overall performance. As the power and heat
increase, the resistance of the voice coil increases as well, causing power
compression, a loss in acoustic output that reduces the system’s dynamic
range. This problem is overcome in the MSR100 and MSR250 by placing
an advanced ferrofluid in the voice coil gap, where it serves to conduct
heat away from the voice coil with much greater efficiency than air. The
results are smooth, natural frequency response and dynamics as well as
stable performance even under heavy use.
