Yamaha NS-690 II Speakers?? Help Identify


I recently purchased a really nice pair of Yamaha speakers at an estate sale that needed refoaming. After fixing them, I hooked them up and can't believe that they sound this good. The cabinets are overbuilt and they are very heavy. Look almost identical to the NS 1000. Does anyone know anything about these? They must be high end. What was the original retail? I have never seen another pair. Thanks all.

I had a pair of these back in '79 also. Mated them with a Yamaha B-2 amp and a Holman preamp. Smooth sound with decent bass down to the mid 30's in my room. Old retail price was $690 (my purchase)
That's about right, the price when I was looking for them was between $675 and $750, which was about $300 less than the 1000's. I too am now looking to get the woffers re-foamed. How much did the job cost you?
I use a pair of rebuilt ns-690's as my main studio monitors---Pleasant and accurate- I find my mixes translate very well!

For the age and price--awsome!

a freind gave me a pair and the bass speaker is blown out on both of them what a good replacement?
I bought a pair in the 70s and still have them and in mint condition. They started to sound scratchy because of the foam disintegrating so I ordered a re-foam kit last month from http://www.simplyspeakers.com. It was easy to repair but you have to take your time getting the old foam off the surround and frame and cost under $30. They sound as good as the day I bought them. A beautiful looking and sounding pair of speakers. I believe I paid about $700 for the pair new.
