In 2019 we marked the fiftieth year of the PA division, and had
the idea of producing a special model of the HS series that would
feature even greater attention by Yamaha engineers. The HS series
embodies the design philosophy on which Yamaha has long insisted
for its studio monitors, and is now available as a special paired
model that uses selected volume parts. The paired model series
bears the designation of MP (Matched Pair), and MP stickers are
affixed to the back of each unit. Manufactured at the same time,
and with paired serial numbers, the “HS MP models” is offered by
Yamaha as a special fiftieth anniversary commemorative model. We
are confident that this special pair of stereo monitor speakers
will play a valued role in your recording, mixing, and mastering
work.
