For the first time in 1982, the NS-2000 is an enhanced version of the old NS-1000 Speaker it was first made in the early and mid 1970s. Like the NS-1000, is a 3-way acoustic speaker system with a suspension and a beryllium-dome tweeter midrange. However, the NS-2000 speaker is totally new, made of pure carbon fiber instead of paper. The cabinet has also been enhanced and is larger and heavier that the NS-1000.
The NS-2000 was superior to Yamaha-of-the-line products, star speaker when it debuted. A few years later, there was the NSX-10000 in limited numbers and is very similar to the NS-2000. The NS-1000xw occurred shortly after the NS-2000, and is essentially a smaller version of the NS-2000. Also of note on the line Yamaha of beryllium-dome speakers is the GF-1.
Woofer
The woofer is made of pure, long carbon fibers that were manufactured in the leaves. Eight of the leaves are linked together to make a cone. The cap in the center is also a carbon fiber sheet formed in a dome. The woofer magnet is 11,350 Gauss and 220,000 Maxwell. The frame is diecast aluminum.
The original boulder in the woofer is made of polyurethane and designed for optimal audio performance. However, it is often fragile and deteriorated in NS-2000 speakers. Fortunately, the replacement of the bank can do for repairers speaker and woofer can continue working.
The answer frequency of the speaker is rated to 28 Hz, causing the NS-2000, a full-range speaker not need a separate subwoofer for low frequencies. The crossing began at 500 Hz
The specifications read that the woofer is 33cm (13 ") diameter. It is 13 inches measured from the outer edges of the frame casting aluminum. The inner diameter of the frame, including the cone and foam edge surround sound, is about 12 inches.
Midrange
The dome of range average 8.8 cm (3.5 inch) diameter and beryllium metal, fabricated by vapor depositing the metal into a mold of the vault. The dome weighs only 0.5 is made of a material that is coated with two types of resins and folded to create folds that are tangential to the dome. This design has the dome firmly, without however, allows the dome to move with precision.
Midrange The dome is covered with a protective metal mesh. The dome is also partially covered by a ring. The ring is designed to function as a sound diffuser to enhance sound dispersion and stereo imaging, but also helps protect the dome. Some owners of the NS-1000 NS-2000 and have experimented with removing the network cable and diffuser hear the difference, but the dome not be touched. The NS-2000 has a cloth cover, and for some purists the sound that makes a sonic difference to them to remove the cover, at least (like the dull sound speaking through a shirt or not).
The average range of operating frequencies between 500 Hz and 6 kHz. The magnet is 18,400 Guass and 150,000 Maxwell. The frame is diecast aluminum.
If input power handling that exceeds, or is defective dome, the dome can crack or break into pieces. If this happens, it is possible that the metal particles Beryllium is released into the air. Beryllium particles in the lungs and body are toxic and carcinogenic. Do not inhale all of the dome.
The control knob midrange level can be turned to adjust the level between +2 dB to infinity (without sound). Perhaps it is better not to move and leave it at 0 dB. The tweeter has a level adjustment similar. Some owners of the NS-1000 NS-2000 and changed its speaker to circumvent these level controls could possibly add distortion. The improved speaker, the NSX-10000, has no such level controls.
Tweeter
The tweeter is a deep design of beryllium dome with a ring diffuser and metal mesh for protection. Opera frequencies of 6 kHz to 20 kHz (and capable of much higher). The size of the dome is 3 cm (1-3/16 ") and weighs only 0028 grams. Similar to mid-range but smaller, also has a tangential surround resin coated fabric.
