Professional Audio Solutions Since 1949 Bold North Audio
Science Serving Music
Bold North Audio products aspire to be the most accurate and thoroughly engineered audio transducers available. Bold North Audio world-class performance is rooted in fundamental scientific research, careful materials selection, precision manufacturing and most of all, love of music.
We harness cutting-edge Klippel vibrational analysis science to reveal the keys to superior audio performance. While we rely heavily on objective science to lead us, we understand that most of all speakers need to tell the musical truth. Our engineers, musicians, and recording studio veterans are the final judges of when a design is worthy of the Bold North Audio logo.
