These are the somewhat rare follow up to the very successful NS-1000.To quote a previuos entry ; " Revised version of the NS-1000 bestseller and masterpiece - still Beryllium loaded.
Besides the straight placement of the drivers, the only tangible difference with the original is the woofer : out went Yamaha's staple white special pulp paper and in came carbon fibers !
Already a lightweight but stiff material, Yamaha made the cone of its new 30cm woofer in eight pieces, bonded together for even more mechanical rigidity ; the carbon fibers are lined from center to edge.
Edgewise-wound OFC copper is used in the voice coil ; the surround is made of impregnated polyurethane foam and the chassis is cast with a special aluminium alloy....
The 8cm mid and 3cm high drivers are essentially the same as those of the NS-1000, with a few manufacturing differences to improve dispersion characteristics and input capacity ; OFC wiring is used here as well.
The enclosure is built thicker with more bracing throughout and beautiful real wood veneer finish.
The result is crystal clear highs, amazingly realistic mids and tight, very solid bass "From the ad when I purchased these: "They have Beryllium dome midrange and treble drivers that have a fantastically detailed and open sound. We have had the opportunity to hear many excellent reference monitors, many costing $20,000 or more. These speakers, made in the early 80's hold their own alongside top studio monitors (ATC, Barefoot, Adam, Focal). These speakers have been well taken care of, both before, and since I received them. The one modification that has been done to both speakers is that they have been re-veneered. They look great, and the wood matches our studios panels, but they do have a slightly different look than the originals (which some might consider a bonus)." The veneer is slightly worn in places, but still very presentable [see the pics]..One midrange driver has a very slight indentation that does not affect the sound in any way..Finally, one of the attenuators for the midrange is not working. The sound from the speakers is well matched and I never felt the need to get it fixed.
The stands in the pictures I had made for $350 and are included...All in all, a fantastic pair of very functional and collectable speakers at a great price..Please see my feedback on Audiogon and Ebay as Pianopig for purchase assurance.Because they are quite heavy, local pick up only..For Paypal add 3% if not using the gift option.I would consider a trade for a solid state or digital power amp or integrated amp of equal value..
