I owned a pair of Yamaha NS10's years ago. IMOH there was not enough low end and there was a little too much top end for me.
I tried using paper and such to cover the tweeder, but my ears could not take more than a few hours on those monitors at a time. They made my ears feel tierd.
Starscream2010, I did a google search on NS-10T, but I got nothing. So I went to Yamaha's web-site and they don't have it listed as one of their products.
Far as I know the orig. NS-10m's were one of the first versions.
And my guess is that...NS, stands for near field speakers
The 10 is for the speaker size, and I believe the "m" stood for monitor
Now the NS-10s....I also understand (if I am correct) that the NS is the same (near field speakers)
10 is the speaker size
But the "s" means studio (they are a newer version)
I don't know what the "T" stands for on your model
I did however find a post about NS-10T on a site called

Hope this helps

NS 10-Ts are the home version ...

The NS10's were originally intended for home use until engineers started using them as studio mons ... I think Bob Clearmountian was one of the first to discover them.

I have seen the "NS10 t's" used in studios and I don't think there are any significant difference between them and the NS10s ...

The NS10 Ms are are an later version of the original NS 10s ... the older NS10 had a tweeter that had a rounded grill and were oriented to be used in a vertical placement, while the NS10ms have a grill with a squared edge and are oriented horizontally...

Thanks! to the both of you :D

I paid $120 for the pair and just was starting to think that maybe I got some bastardized version that was nothing like an NS10, but by name only, because I couldn't find any info about them. I appreciate it.
