PIONEER Pure Malt Series - Limited Edition since 1998

Loudspeaker

Available since 1998, Pure Malt speakers have gained worldwide recognition as leading example of Pioneer's recycling efforts. In the "Resource Recycling Technology & System Awards" presented by the Clean Japan Center and supported by the METI (Ministry of Economy, Trade and Industry), the Pure Malt speaker series won the "Clean Japan Center Chairman's Award" in 2009. Pure Malt speakers were developed in collaboration with brewing and distilling company Suntory Holdings limited, which was seeking a way to recycle casks (made from virgin white oak) that were being used for fuels and other purposes after fulfilling their mission of aging whisky. Oak trees grow for 100 years before serving as whisky casks for another 50 to 70 years. After that the wood is recycled into speaker cabinets that produce warm, rich sounds for many more years. 

The first loudspeaker of the Pure Malt series was the S-PM1000, introduced on September 17, 1998 and it was limited to 1,000 sets. The Pure Malt speakers are more than just eco-speakers made from white oak (one of the world's hardest woods, used for the original Santory barrels) they also feature a newly-designed silk soft dome tweeter and composite cone woofer. A set of matching electronics with Pure Malt design elements and limited to 500 units, were introduced in 1999. These were the A-D5A-PM amplifier (60W + 60W 8Ω, 20Hz-20kHz, 0.05%) and the PD-HL5-PM Hi-bit Legato Link CD player. The Pure Malt series continued in 2000 with the introduction of the S-PM2000 loudspeaker, in 2005 it was introduced the S-A4SPT-PM loudspeaker, in 2006 they were followed by the S-A4SPT-VP (TAD) loudspeaker the S-PM300 loudspeaker and the B-PM1000 rack. The last models were introduced in 2016, these are the S-PM50 and S-PM30 Vertical Twin loudspeakers.

Sansui SP-20000 (1973) - Precision Enginereed

loudspeaker

Sansui has three good things (and one bad thing) to tell you about the SP-20000 three-way, floorstanding speaker system introduced in 1973. First, the bad thing: if you play bad music through it, you hear bad music from it. What could be more fair ? The SP-20000 is a full-bodied speaker system entirely without a "personality" of it's own. That's good. The sound waves it puts out are exact conversions of the electrical impulses it receives from your amplifier or receiver. Thus, good or bad, the material you feed it is reproduced accurately and objectively as the medium of high fidelity can achieve. When you hear the results you'll definitely agree that this is good thing number one. Good thing number two is the fact that two of its three active speaker drivers employ a revolutionary Sansui development called the Direct-Drive Ring Diaphragm - or DDRD for short - to improve phase response, transient response and frequency response. The tweeter and midrange units in the SP-20000 are the first commercially available speakers to use this unique system where the voice coil is the diaphragm, and vice versa. Good thing number three is that the total design of the SP-20000 is integrated right down to the most minute detail. A precision-engineered "passive radiator" woofer is included to smooth and enrich the lows. The crossover and level control system is accurate and extremely flexible. The long-excursion, free-surround woofer is capable of very flat (linear) response at all input levels with reduced intermodulation distortion. And to wrap it up, the SP-20000's sensitivity (93dB/m/W, which is high but not too high) means that inputs from the exceptionally big peak of 100 watts clear down to low-power signals are handled efficiently at any listening level. 

The clean and linear musical reproduction of the SP-20000 goes for any kind of music, from bubblegum to Bartok and from jug bands to symphonies. Sansui markets the SP-20000 by the pair, the right-channel unit is a mirror-image of the left-channel unit in terms of speaker placement. Each matched pair of SP-20000 comes with a pair of two-way speaker stands of attractive and strong aluminum tubing. Speakers may be positioned flat or on a slght angle. Technical data: Woofer - 255 mm cone, Passive radiator - 255 mm cone, Midrange - 90 mm horn, Tweeter - 40 mm horn | Power rating 100 W (Max.) | Impedance 8 ohms | Sensitivity 93 dB/W | Frequency range 25 to 40,000 Hz | Crossover 1.500Hz, 7.000Hz 12dB/oct. L-C parallel type | Dimensions without stand 376 W x 786 H x 320 D mm | Weight 30 kg.

TELEFUNKEN TLX 3 Professional (1978) - Space Age Technology

 

Loudspeaker

Introduced in 1978 the TLX Professional series from Telefunken featured a series of high-tech solutions. The largest model of this series was the TLX 3 Professional which was later replaced by the slightly upgraded TLX 33 model. While the enclosure of the TLX 3 is a traditional particle board with either "metallic-brown" or matte black finish, the front baffle was made of a new type of composite material - a blend of wood particles reinforced with glass-fiber for lower resonance. Built as a 4-way sealed speaker the TLX 3 features a 245 mm long-throw woofer, 65 mm mid-bass dome, 33 mm mid-high dome and a 25 mm dome tweeter. All the dome drivers feature a ferrofluid cooling system borrowed from space technology that helped increasing power handling and damping. The 25 mm dome tweeter is a 3-layer sandwiched material with aluminium as the middle layer. Additionally the tweeter and midrange can be adjusted to adapt reproduction to ambient conditions and to the frequency characteristics of the amplifier and sound sources, the LED bass and treble overload indicator helps you to safely operate the loudspeaker while the tweeter has an additional "Sensistor" protection. Technical data: 200 W Music 120W Nominal power handling | Impedance 8 ohm | Frequnce range 22-25000 Hz | Cross-over frequencies 500/2700/5000 Hz | Dimensions: 35,5x54x27 cm | Weight: 19kg | Original sales price: 750 DM.

YAMAHA NS-1000/1000M (1974) - Pure Beryllium Masterpiece

Loudspeaker

The NS-1000M was the world’s first speaker system to have diaphragms made of beryllium of 99.99% purity — previously considered unobtainable — in its midrange and tweeter. The speaker offered the accuracy and clarity of audio reproduction made possible only by beryllium diaphragms that have an excellent transient response, and earned critical acclaim both at home and overseas immediately after it hit the market in 1974. It was adopted as a studio monitor speaker by the Swedish national broadcasting corporation in 1976, and by the Finland national broadcaster with 200 units ordered in 1978. Even after its successors, the NS-1000X and NS-2000, were introduced, the NS-1000M remained popular and had sold more than 200,000 units over a period of 23 years — before the production of beryllium diaphragms ended and the marketing of the legendary speaker was discontinued in 1997.

Yamaha developed the world's first hard-dome drivers with beryllium diaphragms — the JA-0801 8.8 cm midrange and the JA-0513 3.3 cm tweeter. Beryllium, considered as the ideal diaphragm material for its hardness, lightweight (low density), and stiffness, was extremely difficult to be molded into a diaphragm. Yamaha overcame the challenge of processing beryllium with its proprietary electron-beam vacuum vapor deposition method. The overwhelming sense of spaciousness and clarity made possible by the beryllium diaphragms that took advantage of the metal's sound velocity (higher than that of any other practical metal) shattered the perception people had of speakers — so much so that the NS-1000M, the first speaker system to feature beryllium diaphragms, earned wide acclaim from audiophiles and critics worldwide. Later, the NSX-10000 released in 1986 came equipped with GC beryllium diaphragms made of giant beryllium crystals, and the GF-1 introduced in 1991 featured forged beryllium diaphragms. Until the production of all beryllium diaphragms was discontinued in 1997, a hard-dome driver for Yamaha was synonymous with a beryllium-dome driver.

Positioned as a high-end unit for home use and priced at 145,000 yen at the time of its release, the NS-1000 featured an ebony luxury urethane paint finish exterior, while the NS-1000M, priced at 108,000 yen and aimed at use from the home to the studio, sported a birch semi-gloss black paint finish. With a somewhat large thick-walled cabinet and removable saran net, the NS-1000 weighed in at 39kg, 8kg heavier than the 31kg NS-1000M. As is evident from the difference in price, the cabinet finish of the NS-1000 was lavish enough to rival that of a luxury wood grain piano, but the fearless black design and overwhelming cost-performance of the NS-1000M made it the focus of popular attention. The upgraded NS-2000 released in 1982 and the NS-1000X released in 1986 reinforced the reputation of the original machine, and in the 23 years until the end of all beryllium diaphragm unit production in 1997 it was a long-lasting hit with more than 200,000 units sold.

PIONEER EXCLUSIVE model 2401 (1983) - Studio Monitor Speaker System

 

loudspeaker

The Pioneer Exclusive model 2401 was introduced in 1983. This state-of-the-art loudspeaker was available for the mass market branded as Pioneer while for the professional audio sector it was available as TAD TSM-1. Since day one (1975), TAD Labs has been building only the highest quality, technologically leading loudspeaker chassis. Used in countless recording studios worldwide, the name TAD Labs has become an integral part of the professional scene. TAD's philosophy has remained the same to this day: Technological superiority paired with uncompromising authenticity. Introduced in 1983, the state-of-the-art TAD Labs TSM-1 studio monitor quickly gained an excellent reputation. The clear, precise sound, which reflects the energy and passion of live music like hardly any other loudspeaker, gives these TAD Labs models a near monopoly in the eighties. Even by today's standards these legendary transducers are a coveted collector's item. 

The TSM-1 (Exclusive model 2401) is a scientifically-designed monitor speaker system combining five TAD speaker components - two TL-1601a low-frequency loudspeakers, one TD-4001 high-frequency driver, one TH-4001 stabilized dispersion horn, and the TN-1 dividing network. It was designed for use in large studio control rooms. It provides both high power at all frequencies and superior transient response - a rare combination. Thanks to the use of two parallel-driven low-frequency loudspeakers, the maximum sound pressure level is a particularly high 126dB/W at 1m. Its dispersion pattern is critically controlled, based on tests of actual studio acoustics: response is smooth over a wide listening area, and consistently clear directivity can be enjoyed. Specifications: Impedance 4 ohm (when built-in network is employed) | Frequency range 29-20.000Hz | Input level 300 watts (rated) 600 watts (maximum) | Sound pressure level 98dB/W (1m) | Maximum sound pressure level 126db/W (1m) | Crossover frequency 650Hz | Dimensions 1100x900x712 mm | Weight 145 kg.

Technics SB-AFP1000 (1988) - Superlative Audio Flat Panel Speaker System

 

Loudspeaker

The SB-AFP1000 was an audio flat-panel speaker developed by examining as many as 80 types of test models and thoroughly performing computer simulations. The speaker used a unique twin-cabinet system with both sealed sections and open sections present at the same time in one cabinet. The speaker included eight 30-cm x 80-cm flat units for the low frequencies and four 13-cm x 32-cm flat units for the lower midrange frequencies. In particular, the diaphragm area for the low frequencies was equivalent to a cone woofer with a diameter of 152 cm, and at 124 dB the speaker attained amplitude of 1.27 mm (at 50 Hz). This enabled bass reproduction with low distortion. Characteristic of the AFP was that the bass was emitted in flat waves, and so the system was resistant to adverse effects such as due to indoor refection, and attenuation due to distance was extremely low. As a result, powerful, deep bass extended to the far corners of the space, and the listener was able to feel the subtle air fluctuations with his entire body. The cabinet was given a black-coating mirror finish. The first Audio Flat Panel AFP1000 was delivered to the world renowned Vienna State Opera House for use in playing the performances of singers and orchestras during rehearsals. The modular construction of the AFP System allowed creation of various combinations from "wall to wall" systems to downsized models such as the SB-AFP100 and SB-AFP10.
