The MA2 external speaker is a classic example of early radio-era audio technology from the 1920s. As the largest domestic model of its kind, it found its place not only in French households but across Europe.
It was manufactured by Société des Téléphone Le Las, a company founded in Paris in 1909. Initially specializing in telephones, bells, signaling equipment, and supplies for the navy, mining, and rail industries, the company later ventured into producing speakers and diffusers. While it no longer manufactures speakers, Société des Téléphone Le Las continues to thrive in other fields. Its legacy in audio technology remains a fascinating chapter in the history of radio.
