Bold North Audio MS10-W Replacement Woofer for Yamaha NS-10M

Single 7", 8 Ohm direct replacement woofer for Yamaha NS-10 studio monitors

Product Description

The Bold North Audio MS10-W is a replacement woofer for the iconic Yamaha NS-10M studio monitor woofer, painstakingly recreated to match the exact timbre and tone of the original. This 7-inch, 8 ohm woofer matches the frequency response of the original driver more closely than any manufacturer has ever achieved.


There’s an old saying still murmured around classic studios; “If it sounds good on NS-10s, it’ll sound good on anything.” The Yamaha NS-10M studio monitor is one of the most iconic pieces of studio equipment of all time. The NS-10 rose to fame not for its high-fidelity tone, but for its ability to highlight potential problems in a mix, making them the ultimate solution to translation problems.

Known for their aggressive, midrange-forward sound, NS-10s have graced the tops of recording consoles all over the world for decades. Unfortunately, after Yamaha discontinued the product, Yamaha-made replacement parts are no longer available, forcing many engineers to shelf these tried and true studio monitors… until now.


The Bold North Audio MS10-W Replacement Woofer for Yamaha NS10 exactly matches the sound of the original Yamaha woofer. Using state-of-the-art laser-based measurement tools, MISCO engineers were able to reverse engineer these classic drivers with unparalleled precision. Break out your classic near fields again and discover problems in your mix you never would have noticed on traditional speakers!


The MS10-W is packaged and sold individually, but MISCO highly recommends that NS-10 owners replace both woofers at the same time. Drivers tend to suspensions tend to fatigue over time and no longer perform as they should. For the best imaging and sound staging it is essential that left and right speakers be as closely matched as possible. Replacing both mid-woofers with MS10-Ws will restore your NS-10s back to their original glory, sounding just as good as they did the day you took them out of the box.


  • Seamed paper cone for accurate reproduction of the NS10 woofer timbre
  • Klippel Verified - designed and 100% tested with state-of-the-art Klippel measurement tools
  • Edge-wound copper voice coil
  • 90 dB sensitivity
  • Black powder coated steel basket

Was looking to bring some new life into some old ns-10s, but wanted original woofers. Not as easy to find these days. Was between these and the Avantone remakes but had concerns they would change the sound of the ns-10s. Went with the Bold North Audio woofers at the suggestion of my VK rep and was pretty surprised how much they sound like what I remember original ns-10 woofers sounding like. Definitely brought new life and detail to the mids and low mids compared to the original woofers I replaced, but without changing the overall color of the speakers. Would confidently purchase these again as replacement woofers for original ns-10 woofers.

Many thanks, the drivers seem to be nearly perfect replicas of the original.
However whilst i have you, one of my boxes seems to be dishing out more bottom end than the other? I'm just wondering if one of the x-overs is playing up? do you have a cct diagram?

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.

From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
