Founded in 1971, Eastech is one of the largest loudspeaker manufacturers in the world, with approximately 6,000 global employees including over 160 engineers specialized in acoustics, electronics, hardware, software and systems engineering. The company is headquarter in Taipei, Taiwan (Eastech is listed on the Taiwan Stock Exchange), and currently owns R&D facilities in
Videbaek, Denmark (Scan-Speak) and Hui Yang, China, directly integrated with the company's software and electronics R&D facilities in Hui Yang, Shenzhen and Singapore.
Eastech's core business combines manufacturing complete audio systems - from headphones, to soundbars and complete speakers - with manufacturing transducers for the mass consumer market, as well as for pro audio and automotive applications. The company's state of the art manufacturing facilities in Hui Yang, China, are a vertically integrated operation, able to handle plastic injection, electronic production, wood assembly and processing, and incorporating an advanced, high-capacity automated transducer production operation.
The company's engineering capabilities and acoustic expertise allows Eastech to handle high-quality loudspeaker projects, from transducer design using Comsol, FEMM, and Loudsoft software for acoustic modeling and tuning, perform 3D Finite Element Analysis to simulate and optimize the acoustic profile and system’s mechanical structural design, and perform rigorous evaluation and design characterization using Listen and Klippel measurement solutions.
Punktkilde, designed by Scan-Speak, produced by Eastech is the tagline that translates the brand's intention of pursuing supreme sound quality, acknowledging its Danish heritage on designing premium quality transducers. Within the relatively recent Punktkilde range, we can find already a number of interesting innovations and original designs, including some great looking woofers and tweeters using distinct metallic red baskets and frames (see the Punktkilde FSA044010-0802 Titanium Dome Tweeter Test Bench here), a complete line of ultra-thin woofers, and patented “dual-surround” suspension woofer designs.
Another innovation that Punktkilde has been perfecting is part of its new Radial Magnet Transducer Series, a unique slim design that is ideal for soundbar and portable speaker applications, targeting premium audio qualities. This series uses a patented dual suspension design with a dual-ring radial structure on a magnetic motor system for improved BL(x) and Kms(x) symmetry performance. A key advantage is its very low distortion comparing to conventional magnetic motor designs. A very exciting development from Punktkilde with new products now being introduced.
Five New Transducers
Among the latest products confirmed by Punktkilde, we can find the AUGWL0030-JN02, a 12" ferrite magnet 8 ohm woofer with bump bottom plate and high excursion voice coil. The woofer features an aluminum shorting ring (Faraday shield), semi-pressed paper cone (40% pulp and 60% carbon fiber), foamed rubber surround, 75.5mm (3”) diameter voice coil wound with CCAW wire. Basic specifications and Thiele-Small parameters detailed include 91dB 2.83V/1m sensitivity, 200W long term IES 17.3 power handling, Qts=0.398, Fs=34Hz, 5.5Ω Re, and Xmax=3.75mm.
Next is the AUGFL0005-JN08, a 2" diameter neodymium magnet 4Ω full-range driver that features a 1" diameter voice coil wound with CCAW, a black anodized aluminum cone with a rubber surround, 83dB 2.83V/1m sensitivity, and 15W long term IES 17.3 power handling. T-S parameters include: Qts=0.38, Fs=130Hz, 3.4Ω Re, Xmax=1.25mm.
Part of the latest Radial Magnet series is the AUGWL0006-JN01 ultra-thin (27.1mm depth) 2.25” diameter neodymium magnet 4Ω woofer. This slim woofer features a 35.6mm (1.4”) diameter voice coil, a black anodized aluminum cone with a rubber surround. Rated specifications detail 82dB 2.83V/1m sensitivity, and 10W IES 17.1 power handling. T-S parameters include: Qts=0.63, Fs=158Hz, 3.4 Ω Re, Xmax=2.2mm.
