En mi caso, tenía un AJ518A, fundido en mis Yamaha NS-10M Studio. Y compré como recambio. Se nota muy clara la diferencia entre ambos. Este es mas brillante. O se cambian los dos, o el sonido queda desequilibrado.
Si estás acostumbrado a ellas, recambios originales. Si no, sustituye los componentes de tus yamaha NS-10, por pares.

In my case, I had an AJ518A, cast in my Yamaha NS-10M Studio. And I bought this as a replacement. The difference between the two is very clear. This is brighter. Either the two are replaced, or the sound is unbalanced.
If you are used to mixing with Yamaha, original spare parts. If not, replace the tweeters of your yamaha NS-10, in pairs. AV-10 or AJ518A
