Progress of contemporary speaker design reveals disparities through BBC's 50-year-old LS3/5A mini monitor
The LS3/5A, a small monitor loudspeaker designed by the BBC in the 1970s, has earned a legendary status in the world of audio. Created to meet the BBC's stringent audio quality requirements, particularly for use in television studios and monitoring situations, this compact speaker has left an indelible mark on the industry.
Measuring just around 30 cm tall and with an internal volume of 5 liters, the LS3/5A is an ideal choice for small spaces where accurate sound monitoring is essential. Its sealed cabinet design helps achieve a tight and controlled bass response, while the use of KEF B110 and T27 drivers, along with a hand-tuned crossover, provides a balanced sound with good midrange clarity and high-frequency detail.
The LS3/5A reaches down to only 70Hz (-3dB), resulting in a rich and somewhat unwieldy sound. This characteristic, combined with its limitations in terms of authority, dynamics, and power, is more apparent when compared to modern alternatives. However, some enthusiasts continue to be enchanted by the LS3/5A's natural reproduction of vocals and its ability to disappear in an aural sense when positioned carefully.
In comparison, modern high-quality standmounters like the KEF LS50 Meta, Epos ES-7N, Acoustic Energy AE300 Mk2, and Bowers & Wilkins 607 S3 offer enhanced dynamics, bass extension, or detailed imaging. These speakers benefit from newer materials and technologies that improve sound quality and efficiency.
Despite its age, the LS3/5A continues to hold its own. Its accurate and neutral sound signature, combined with its gentle delivery, makes it easy to enjoy over long listening sessions. For instance, Nirvana's Nevermind sounds notably gentler through the LS3/5A compared to usual. Originally developed for use in outside-broadcast vans and cramped studios, primarily to monitor speech, the LS3/5A's legacy endures, offering a unique listening experience that still captivates audiophiles today.
