Ocean Way Audio
History

It all started with speakers. Ocean Way Recording began in 1968, as a showcase for
Allen’s custom monitors.
Allen needed impressive sounding material for his speakers so he began to record music
that sounded dramatic! The studio business boomed and he met the demand with many
rooms in several locations. At the peak of the studio business, Allen designed and owned
four recording studio complexes.
Five time Grammy® Award winning Allen Sides has personally recorded over 1,000
albums, many of which have become audiophile classics. He has worked with the finest
and most famous artists of the last four decades. Albums recorded in Allen’s studios have
sold over a billion copies. Allen’s hearing capabilities enables our engineers to translate
every sonic nuance, bringing a new dimension and understanding to what is possible in
high-end speaker design. His ears are our final design tool.
