Excellent Condition Yamaha NS-500M Studio Monitors
These are not common and less common in this condition. The combination of components used in this speaker is unique in the Yamaha lineup.
Tweeter - 5 cm Beryllium Dome JA-0544
Midrange - 10 cm Composite Dome JA-1214
Woofer - 30 cm Carbon Fiber Dome JA-3109
The carbon fiber 12" driver when in direct comparison to the NS-1000 cabinet makes MUCH
deeper and more easily accessible bass. I have also heard one of the NS-1000M pairs with
carbon fiber domes which also made much better bass than the paper versions. Also, this
cabinet has a significantly larger volume than the NS-1000 for bass production. This is a very
unique aspect of this speaker as the NS-1000M has consistently to me seemed bass shy!
Playback frequency band 40Hz ~ 20000Hz

External dimensions Depth 678 × height 374 × 324.5mm width
All of the drivers work perfectly and sound amazing. The tweeters are clear and sweet sounding. The composite dome mids are much more forgiving of source material than the beryllium mids of the NS-1000. The cabinets are in excellent condition. The only flaws here are several small 5mm holes in the grilles - 3 holes total count - and all lie over black plastic portions of the grille frames so are not obvious.
Thanks for looking...!
