Classic Rogers LS3/5a 15 Ohm – BBC Licence.

Rogers over seventy years of excellence.

For over seventy years the name of Rogers has earned the high regard of music lovers worldwide with the high standard of musical integrity it’s products have consistently achieved.

Founded in 1947 in North London, by Jim Rogers, a highly successful range of thermionic vale equipment was produced, including several exquisitely built amplifiers.

Later in the 1960’s and early seventies, Rogers was one of the first British companies to lead the way with good sounding transistor amplifiers and tuners.

During this period many loudspeaker designs from a new factory in Catford, London, culminating in 1970 with the introduction of the LS3/6 studio monitor. This was the first BBC licensed design and heralded a significant advance in moving coil loudspeaker performance.

This was followed four years later by another BBC licensed design, the legendary LS3/5a. Undoubtedly one of the all-time greats in loudspeaker design it has inspired more interest and critical acclaim than almost any other product. Now*  entering its forty fourth year of production it continues to astonish and impress listeners the world over with its fine musical performance.
