Yamaha NS-10

The Yamaha NS-10 is a loudspeaker that became a standard nearfield studio monitor in the music industry among rock and pop recording engineers. Launched by Yamaha in 1978, the NS-10 was intended as a hi-fi bookshelf speaker for domestic environments. It was received poorly by its intended audience, but became a staple for recording studios and freelance audio engineers due to its perceived ability to reveal poor quality in recordings.

The speaker is known for its exaggerated treble response, which some engineers, such as Bob Clearmountain, sought to dull by hanging tissue paper in front of its tweeter. The NS-10 has been used to monitor a large number of successful recordings by numerous artists, leading Gizmodo to refer to it as "the most important speaker you've never heard of".
