AUDIO SOCIETY
Date: Sunday, July 13, 2014,
6:00 PM
Place: Boston University, Life Science & Engineering
Bldg, 24 Cummington St, 1st Floor Conference Room:
(Room 103), Boston, MA 02215
Topic/Activity: The King Audio
Electrostatic Loudspeaker (Prince III)
& the electrostatic KS-H3 Headphones
Roger DuNaier of Performance Devices
will travel to the East Coast from Torrance, CA, to
demonstrate some of the King
Sound electrostatic technologies. Performance
Devices is the exclusive US distributor for King Sound
and will demonstrate the Prince III full-range speaker
system and two electrostatic headphone systems. The
The $14,995 King III (Prince III’s bigger brother)
was rated ‘Best of the Show’ by the Absolute
Sound Magazine in their AXPONA (Audio Expo North America)
2014 report. The show was held from April 25th through
27th at the Westin O'Hare in Chicago.
The CNET earphone of choice,
the KingSound
KS-H3 headphones, was highly rated by Steve
Guttenberg. He said they are ‘Astonishing headphones
with clarity like you've never heard before.’
David Cohen of Hegel Music Systems located in Framingham,
MA, will be present and has graciously agreed to supply
their highly regarded electronics for the demonstration.
King Sound is a well-established
electrostatic loudspeaker manufacturer in Hong Kong.
King Sound products retail in the UK, Italy, Canada,
US, China and Australia. The 13 year old company has
already earned a reputation for high performance and
very competitive prices. Audiophiles around the world
have been taking notice of the once small manufacturer’s
pledge to bring genuine high fidelity back into your
listening room. Alvin Foster, BAS founder, has maintained
at their Annual BAS Consumer Electronics Show Review
Meetings that the KS-10 electrostatic speaker is among
the best items demonstrated at CES. For the last 5-years
Foster has always categorized the KS-10 as one of
the most accurate speakers auditioned at CES.
As always, you do not have to
be a BAS member to attend.
Refreshments will be available at 5:30 PM.
See the AXPONA notice below.

Best Sound (for the money):
King Sound King III electrostatic loudspeaker (pictured
above).
While I don’t have the space to go into the usual
detail, several other loudspeakers managed to make
very good sound in Chicago.
The $15k King Sound King III
electrostats, for instance, were perhaps the most
lifelike speakers at the show on voice. (Mel Torme
was “right there” on “Once In Love
With Amy"), but then ’stats are famously
great in the midrange and, because of their figure-eight
radiation pattern, more immune to some of the room
effects that plagued most of the dynamic loudspeakers
at the Westin.
In any event, I really liked the King III's and was
pleasantly surprised by how natural their bass sounded,
even if it wasn’t as deep or as hard-hitting
as that of the Wilson Alexias.
(The King III was a close contender
for one of my Top Five System slots.)

other meetings and notices which may be of interest
to BAS members |

When collecting
and plotting "noisy" data it is often
useful to have Microsoft Excel plot a Trend
Line through it. If that data is to be
used for further work, it may be necessary to
have an X-Y table of the Trend Line. That is
not easy to get and this paper will show how
to do it.

Numerical Data from an Excel Trend Line

disk drive. Includes lifetime electronic program guide service.
