The Neutrik speakON® Series, known in the professional
audio industry as "The loudspeaker connector" has become
the state of the art in speaker and amplifier connectivity.
Introduced in 1987 speakON was invented by Neutrik as a
result of customer demand for a reliable speaker connection.
The pro audio market quickly realized the advantages of this
completely new connection system.
The design is optimized for loudspeaker applications with
an outstanding cost-performance ratio. As market leader for
speaker connections we are proud to offer an all-encompassing product line for the specific needs of today‘s market. Recent designs such as the STX series and the speakON
Combo offer solutions for nearly every speaker application.

Integrated Design
One of Neutrik's goals is to create products that are
easily distinguished from other manufacturers. We have
successfully achieved this in our engineering efforts as well
as the patent and trademark protection granted for our
unique products. To further establish a clear difference
between Neutrik and our competitor’s products we give
our customer the means to easily identify original Neutrik
products. Therefore all of our new products such as the SPX
and the STX series are designed according to the protected
integrated design. (EU-Pat.: DM/057 379, US-Pat. Pending,
