Besondere Ausstattungen

Pegelregler für Hochtöner

Klingen Bombe, Passiv es gibt kaum infos darüber im Netz. Eine Box wiegt gut 14 Kilo früher wurde noch geklotzt.

Versenden kann ich kostet aber dementsprechend.

Den Tieftöner würde ich sagen dass es 8 Zoll Größe hat.

Sieht aus als wurden sie gerade ausgepackt, anbetracht der Tatsache, dass sie schon gut 50 Jahre alt sind...hervorragend.

Our Thoughts RADAR AI

This is a seller’s market for vintage Yamaha speakers, and the €399 asking price for the NS-645 pair is fair, sitting just above the estimated median of €255 but well below the typical used range of €200–€350. While not a bargain, it’s a reasonable entry point for a well-regarded 2-way system from 1977 that delivers deep, live bass and rivals modern speakers at a fraction of the cost.

The NS-645 remains worthwhile due to its robust JA-2502 cone bass driver and soft dome tweeter, offering a frequency response of 40Hz–20kHz with 50W power handling. Its vintage appeal, original-owner condition potential, and compatibility with classic amps like PS Audio’s Model One make it a compelling buy for enthusiasts seeking authentic hi-fi character without overspending. No caveats are needed for this clean listing at a fair price.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Yamaha

Yamaha stands as one of the world's most storied audio manufacturers, with roots extending far beyond consumer electronics. Founded in 1887 by Torakusu Yamaha in Hamamatsu, Japan, the company began as a reed organ manufacturer before expanding into pianos and eventually becoming a comprehensive musical instrument maker. This deep heritage in acoustics and materials science would prove foundational to its later audio ventures. The company operated under its original name, Nippon Gakki Co., Ltd., until 1987, when it was renamed Yamaha Corporation in honor of its centennial.

Yamaha's entry into high-fidelity audio proved transformative for the industry itself. In 1954, the company released the Yamaha Hi-Fi Player, widely recognized as the world's first audio component to bear the "Hi-Fi" designation in its name. The company subsequently built a comprehensive product portfolio spanning amplifiers—beginning with the acclaimed A-100 in 1960—speakers, turntables, and digital audio equipment. The NS-1000 speakers, introduced in 1974 with beryllium drivers, became iconic reference monitors. Yamaha also pioneered digital audio technology, shipping the world's first CD recorder in 1988.

Today, Yamaha occupies a distinctive position as a mid-to-high-end generalist rather than a niche specialist. The brand commands respect among both casual listeners and serious audiophiles, balancing accessibility with genuine engineering credibility. Its reputation rests on six decades of consistent innovation, proven reliability, and the unique advantage of applying musical instrument expertise to audio reproduction. Vintage Yamaha components remain highly sought by collectors, while current products maintain the brand's tradition of delivering performance and durability across multiple price tiers.
