The Commonwealth Club of California is the nation’s oldest and largest public affairs forum reaching more than 25,000 people per year. After 100 years of leasing space, The Club needed a permanent headquarters to broadcast over 400 annual events ranging on topics from politics and culture to society and economy. Salter provided acoustics, audiovisual, telecommunications, and security consulting for the chosen 1910 historic building along the San Francisco Embarcadero.
A Vision for Functionality and Aesthetics
The project program called for presentation audio or background music in every public space in the 22,000 square foot building as well as outside. In addition to the main auditorium, The Club also wanted intimate viewing spaces for guests to enjoy food and drink while watching the broadcast. The project challenges included:
- Delivering a high profile show space on a non-profit budget
- Working within constraints of limited square footage and historic building regulations
- Providing concert-quality sound without compromising aesthetic standards
- Acoustics issues such as speech intelligibility, sound isolation, and ventilation system noise control
Strategic Connections and Coordination
Our team worked closely with the project designers, suppliers, manufacturers, and technical team to provide the following solutions:
- Strategic speaker and microphone placement with acoustically transparent fabric to make many of the 50 speakers and 20 microphones in the auditorium invisible
- Reclaimed wood from original structure used for sound-absorbing walls

Turning an Event into an Experience
The Club now has its first permanent headquarters equipped with a state-of-the-art audiovisual system meeting high aesthetic standards. Benefits include:
- High-end sound system featuring Meyer Sound variable acoustics Constellation System, donated by Meyer Sound, in the 300-person auditorium
- Audio, video, and data connectivity in entire building allowing for the same media to be experienced in multiple places at once
