The Installation Series speaker line was conceived and produced through a unique and powerful collaboration of two companies and two engineers. Audio Composite Engineering, also known as ACE, and their gifted Acoustic Engineer Michael Adams were retained by Yamaha to realize the installation series concept of Yamaha's legendary speaker engineer Akira Nakamura. For over 4 decades Mr. Nakamura had developed a wide variety of musical instruments, as well as hi-fi and commercial speakers, the most famous speaker being the legendary NS-10M studio monitor.

With over 3 decades of experience as a speaker designer and front of house & monitor mixing engineer, for the likes of Jimmy Buffett, Jackson Browne, Warren Zevon, Emmylou Harris and others, Michael Adams has developed speakers for major manufacturers and installs.

By combining into a single team, a synergy was created to deliver the most natural and accurate sounding loudspeaker line. Built in the USA, Yamaha applies the same precision and build quality as found in our fine pianos, which are also manufactured at the same facility.

We reinforce our consistent and outstanding build quality with a 5-year manufacturers warranty. Our factory capacity and commitment to on time delivery means you won't be left hanging when your project is ready to go.
The Installation Series provides a wide range of models with seamlessly integrated hardware to meet the expectations of contractors and end-users for audio quality, ease of installation and system design.

The exceptional uniform phase response is key to the accurate sonic performance of the Installation Series.

Common phase response design throughout the line minimizes the reduction of sound level and unwanted coloration in the "overlapped" area when combining/arraying speakers.

The phase differential among all models is designed to be less than 90 at 2kHz.

This achieves a minimal variation in phase response in the off axis performance, and the overall effect on frequency response is held to a minimum, ensuring a consistent family sound of speakers.
