The MS10-W: True to the Original

The Ideal Replacement For The Yamaha™ NS-10™ Woofer

Introducing the most accurate reproduction of a Yamaha NS-10 woofer yet developed. Many have tried but none have succeeded in creating a replacement driver with 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 NS-10’s woofer performance but to exactly match its sound. Making a drop-in replacement driver with a white cone is easy; getting a perfect sonic match is very difficult. Learn more from the Tech Brief

If you're looking for the original performance from the NS10, you need to consider the Bold North Audio MS 10-W.
