Holy Grail of Yamaha Monitor NS-1000 one of the best monitors ever made in great condition Rare at a great price

World Renowned as the kings
These are at a great price

As is great condition selling for over 3k and above


These are possibly the coolest speakers Yamaha ever made and by far their most famous. They were ground breaking at the time, as they used actual BERYLLIUM for the midrange and tweeter diaphragms!

Subsequently they made a million different cheaper variations of the NS-1000's to cash in on the fame and attention these received. But don't be fooled, these are the original Holy Grail version which every audiophile should own at some point.

Made of solid wood these weigh in at over 65 lbs each. The gigantic woofer baskets and magnets probably add substantially to the weight.

These are the "M" studio version, identifiable by the tone controls mounted in the front which makes them much more desirable than the home model.

The drivers on these speakers are absolutely perfect and work as if they were new. They were fully tested

The Yamaha NS-1000 series, introduced in 1974, consists of legendary 3-way monitor speakers famous for being the first to use beryllium domes for midrange and tweeter drivers. They are highly regarded for their surgical transparency and low distortion, remaining competitive with modern studio

Models and Key Differences

The series is primarily divided into a domestic version and a professional monitor version, sharing identical internal components but differing in cabinet construction: 

Yamaha NS-1000: The domestic version features a heavier solid wood enclosure with a rosewood or ebony finish, weighing approximately 39kg (86 lbs) per speaker.

Yamaha NS-1000M: The "Monitor" version, designed for studio use, uses a veneered chipboard cabinet with a black ash finish. It is slightly lighter at 31kg (68 lbs) but features a more rigid cabinet for professional environments.

Yamaha NS-1000MM: A much smaller mini-monitor version (approx. 11 inches tall) meant for bookshelf use, with lower power handling and 6-ohm

Technical Specifications

According to manufacturer data and expert reviews from Audio Nostalgia and Sound On Sound:

Drivers: 300mm (12") paper pulp woofer, 88mm beryllium dome midrange, and 30mm beryllium dome tweeter.

Frequency Response: 40Hz to 20,000Hz.

Sensitivity: 90dB (1W/1m), making them relatively efficient.

Crossover Frequencies: 500Hz and 6,000Hz.

Impedance: Nominal 8 ohms. 



Performance and Sound Signature

Transparency: Reviewers from Hi-Fi News describe the sound as "forensically detailed" and ultra-explicit, similar to high-end electrostatic designs.

Bass Performance: The sealed enclosure (infinite baffle) provides fast, tight, and phase-accurate bass, though some experts find it lacks sub-40Hz extension compared to modern ported designs.

Amplification Synergy: These speakers are notoriously revealing of electronics. Stereophile testers note they sound best with high-quality tube electronics or smooth MOSFET/VFET amplifiers, as they can sound "biting" or "strident" with some solid-state equipment.

Adjustability: They feature front-mounted L-pad attenuators for fine-tuning midrange and treble levels to suit
