|Hong Da Industrial Co (HK) Ltd manufactures a comprehensive range of small, medium and large speakers from the low-end to hi-fi quality|
In the space of just 10 years, Hong Da Industrial Co (HK) Ltd has moved from the production of basic low-end speakers into superb quality speaker systems, including large units suitable for use at outdoor concerts.
"Following paper-cone speakers, usually with plastic frames, we soon moved on to Mylar speakers with metal frames," says Director Tung Man Lung. "These high-definition units have significant performance advantages, and are especially well suited for today's multimedia home theatre environment."
The range of Mylar speakers includes transparent and black models, and flat and radial types. "They may incorporate an Alnico inner magnet or a ferrite outer magnet. Typical FOB Hong Kong unit prices for inner magnet designs range from US$0.35-0.38, while outer magnet types cost about US$0.13 each," says Mr Tung.
"We bring to market an entire range of speaker products for indoor, outdoor, car and home entertainment systems, and they can be as diverse as designs for ceilings or as complete home theatre systems," he adds.
Hong Da Industrial Co also produces tweeters, dome tweeters, sub-tweeters, Mylar speakers, car speaker component systems, piezo-ceramic elements and buzzers, poly-varicon variable capacitors, receivers, antennas and condenser microphones.
"Nowadays, there is a lot of novelty in retail goods," Mr Tung declares, "which is one reason why we design speaker frames in unusual forms. For example, we have one shaped like a large green mushroom. Another is in the shape of a boulder."
The company has also cooperated closely with famous client firms such as Philips, Daewoo, Sharp and Sanyo, while its own HD and HDS brands have also established a market presence.
"Our OEM clients were mostly large, well-known makers who incorporated our speakers in their products. This enabled us to move into product development, working with new materials and designs, building up our know-how and finally advancing into ODM," Mr Tung recounts.
"As our products improved, so we were better able to attract new customers, with important buyers in Europe, the US and Japan, while the UK has always been a good market for us, as has Japan. More recently, Australia, South Africa and the Middle East opened up."
Home entertainment/theatre systems offer the best profits, followed by miniature speakers for portable devices. "Those small, common speakers are ordered in much larger quantities," Mr Tung says. "They are used mostly in toys, telephones, radios and fax machines."
The highest quality speakers the firm offers are used in hi-fi systems, and feature fibreglass or titanium-surfaced paper cones. "We sometimes use aluminium, but not for the very high-end," says Mr Tung.
Model HW-1204 is a 12-inch paper-cone woofer with a durable foam layer surround, voice coil, 4- or 8-Ohm impedance, 350 watts maximum power and a frequency response of 25-4000Hz.
The HDS-5540 is a five-speaker home theatre system, one among many options from Hong Da Industrial Co, and comes with a total output of 120W. The woofer size is 295x270x283mm. As for the satellite components, the front speakers (two) measure 820x215x265mm; the centre channel (one) measures 364x163x163mm, and the surround speakers (two) measure 245x153x163mm.
"We are ISO 9002- and CE-certified," says Mr Tung. "We are also using the SGS test at present because it covers automotive parts qualified as meeting European environmental standards."
With such clarity of purpose, it sounds as if Hong Da Industrial Co is well on track for a continuing successful future.
