The ‘Sarnoff speaker’ is considered the rarest and most exotic
horn receiver in existence today. Considered too valuable to reproduce, this
beautifully crafted speaker has a permanent home at the SPARK Museum of
Electrical Invention. The remarkable story of how this one-of-a-kind speaker
came into existence, and how the Museum ultimately acquired it, begins at
the turn of the 20th century, with the first radio receivers.
The first radio listeners often wore two, low-resistance telephone earpieces
connected by a wide leather strap, creating the world’s first headset, or now
commonly referred to as headphones. Nathaniel Baldwin is commonly
credited with inventing the first practical headphone (1910). A fine example
is C. Brandes Inc.’s “Superior Matched Tone” Headphones, New York, USA
“For Land, Sea and Air!” This superior headset incorporates a unique driver
system that amplified sound with a clarity that became an industry and US
Government standard. Headsets were already sold to thousands of
switchboard operators, but as broadcast stations began to pop-up all over
the country, and radio became available everywhere, radio enthusiasts
lined-up for this necessary component. But even with improved fidelity,
many Americans felt limited and tethered by their headsets.
It seemed only natural to share the experience of radio with others, and
soon entire families were listening off a single headset by placing it in a
wooden bowl or cardboard box to amplify the volume.
Legend has it that someone over at Magnavox corporate headquarters
accidentally dropped a telephone earpiece inside a horn of an Edison
Amberola Cylinder Phonograph and the voice emanated with such volume
that it could easily be detected two blocks away. (So the first horn speakers
were little more than an amplified telephone receiver laid flat and used as a
base for a horn or cone.)
This event launched Magnavox into the public address loudspeaker business
and soon rooms-full of people everywhere were listening and dancing to the
sounds of a single radio. By the 1920s radio was big business and it seemed as though everybody
was trying to get in on the phenomena. Americans with little or no
experience producing radio equipment suddenly flooded the market with a
creative array of speakers. Most were not successful. Many of the existing
horn speakers from that era are one of a kind, and some are truly amazing.
Certainly one of the most inspiring examples from the period is the Seatone
speaker, made by the Tonk Brothers of New York. Rumored to have
mastered their trade making manhole covers, in Yonkers, this is their first
and only known attempt at producing a horn radio speaker—but what an
attempt it is! The Seatone is 26 inches of heavy brass, cast in the shape of a
woman standing barefoot at water’s edge, holding above her head an actual
seashell, where the sound “flows-out”.
Yet as hard as they tried, the American designers and manufacturers failed
to match the fine, Old World craftsmen of Europe. One need only glance at
the Museum’s display of European radios and receivers from the 1920s to
realize how imaginative and skilled their creators were.
Here we see scores of beautifully crafted horn-type speakers in all shapes
and guises: There’s the lavish serving bowl forged out of a polished silver, a
charming hand painted floor vase, even a jade green glass shaped like a
Chinese philosopher—all fully operational radio speakers. The English,
French and Czech’s were making more than just good radio equipment, they
were producing fine works of art, and everyone knew it, including Mr.
In 1924, David Sarnoff was president of the Radio Corporation of America
(RCA), and later became the founder of the National Broadcasting
Corporation (NBC). He was considered the most powerful and influential
character in the history of radio, and color television. Often compared to
Caesar, Patton, and Captain Ahab, Sarnoff became the very definition of the
cigar chomping mogul, and characterized in countless books and films.
That same year, Sarnoff commissioned a group of artisans in Czechoslovakia
to construct the two most beautiful and unique horn speakers imaginable.
The idea was to produce an appealing, ultra-high-end speaker for serious
audiophiles, AND, collectors of unique art. Upon completion, the two
speakers were sent to Sarnoff along with the estimated cost to produce
What Sarnoff saw was like nothing attempted before or since. The taller of
the two prototypes stands at just over 2 feet. The horn is a straight, classic
gooseneck design and a seamless blend of wood, brass and metal. Hundreds
of minute, cut-glass beads are set in swirling arcs and accented with mother
of pearl. The Sarnoff speaker is made with the kind of detail and symmetry
that make this the rare instrument it is. One can only imagine Sarnoff’s face
when he first saw the speakers.
It’s much easier to guess his look when first seeing the bill.
The cost was staggering, even for Sarnoff, who immediately realized the
speakers were too impractical to reproduce or sell to the American market,
no matter how beautiful or well made. The speakers remained in storage at
RCA for over fifty years, until discovered by Ralph “Doc” Muchow, a
Midwestern dentist, and one of the world’s premier radio collectors.
The Sarnoff speakers were displayed in the Muchow Museum until 2001
when Muchow died, and the speakers were sold at auction. The taller, more
valuable ‘flute’ speaker was purchased by the Museum’s co-founder John Jenkins.
The speakers featured in this article—along with many, many
more—are on display in the Museum’s extensive galleries. There’s nothing like experiencing this remarkable collection in person, less than an arm’s length away.
