History: |
The Rogers company was originally founded in 1947 by Jim Rogers and started advertising as speaker and amplifier component suppliers. [1] By 1951 they advertised a range of High-Fidelity equipment branded as RD such as the RD Williamson model D amplifier along with pre-amplifiers and tone networks. [2] Around 1955 the company changed its name from Rogers Development Ltd. to Rogers Development (Electronics) Ltd. [3] In 1975 Brian Pook became managing director. The company was a licensee for the manufacture of the LS3/5A and LS3/6 BBC Monitor speakers but was struggling to maintain production because of unreliable/unavailable supplies. In October 1975 it went into receivership. This notice appeared in Wireless World, January 1976, page 36. Rogers packs up It's sad to record the demise of yet another small British company making high-quality products. Rogers Developments (Electronics) Ltd, manufacturers of audio equipment including amplifiers, tuners and monitor loudspeakers, ceased operating on October 31, 1975. This was followed by this advert from Wireless World Mar 1976, Page 52. Swisstone Electronics Ltd., 4/14 Barmeston Road, London SE6 3BN is a new company that will specialize in the servicing of Rogers audio equipment.
In 1976, Jim Pook and 5 other ex-employees purchased all the Rogers items at the liquidator's auction, bought the Rogers name from the receiver, leased the factory, renegotiated the BBC LS3/5A license, and started the business again, with financial support from Michael O'Brien, under the” off the shelf” company Swisstone Electronics Limited. A new design was developed in-house, using a special bass unit (from Dalesford in Yorkshire) and rationalised the design for manufacture, resulting in the Rogers Export Monitor speaker, a product free of any BBC licence. Exporting became a key part of the new business. 1978 Acquired the Chartwell Company (a company started by former BBC employees who had taken a licence to make the LS3/5A, and operated from a factory in Mitcham), acquiring the BBC profile cone moulding tools from Hyder Cones and making speaker drive units in-house which were used to create the Rogers Studio 1 speaker. 1980s Rogers loudspeakers were still being made by Swisstone. In 1993, Rogers became part of the Wo Kee Hong Group. Through this group's vast worldwide network, strong financial background, and modern management, Rogers entered into a new era and in 1995 brought out the revolutionary single-driver subwoofer AB-1 (Auxiliary Bass One) model designed specifically to address the limitations of the LS3/5A.
