Professional Audio Solutions Since 1949 
Seventy years ago, MISCO founder Cliff Digre—the son of Norwegian immigrants—had a bold vision: Challenge the loudspeaker industry with the most powerful and creative solutions to provide the best music experiences for listeners everywhere. This vision of boldness lives on, inspiring MISCO's most scientifically accurate pro-audio loudspeakers and audio systems to date—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 to reveal the keys to superior audio performance. While we rely heavily on scientific data 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.
The NS- 10TM Woofer's Most Accurate Reproduction
Introducing Bold North Audio's MS10-W. Many have tried but none have succeeded in recreating the exact timbre of the woofer used in the most widely used studio monitor in history…until now.
MISCO’s goal in developing the MS10-W was not to improve upon the Yamaha NS-10’s woofer performance but to exactly match its sound. Making a drop-in driver with a white cone is easy; getting a perfect sonic match is very difficult.
