Ask most people to name Indian audio brands and they’ll say Boat, JBL, or Bose — but serious audiophiles in Kolkata and across eastern India will mention Sonodyne. It’s one of India’s oldest and most respected speaker and audio equipment manufacturers, with a history going back to the 1970s. Here’s who owns Sonodyne India and why it still matters in the Indian audio space.

Who Owns Sonodyne India?
Sonodyne India is a privately held company owned by the Banerji family, founded by Amar Nath Banerji in Kolkata in 1974. It is one of India’s oldest domestic audio equipment manufacturers, predating the consumer electronics boom of the 1990s by nearly two decades. Sonodyne designs and manufactures speakers, amplifiers, and professional audio equipment, and has supplied audio systems to institutions, auditoriums, and home audio enthusiasts across India. The company has remained family-owned and independently operated, unlike many Indian electronics brands that either partnered with foreign companies or were acquired. Sonodyne has also developed professional audio products used in commercial installations, broadcast, and cinema. For more Indian audio electronics context, see Indian electronics brands.

My Take on Sonodyne India
Sonodyne is a quiet achiever in Indian audio — a brand that built real engineering credibility over fifty years without the marketing budgets of Boat or the global reach of Bose. For audiophiles in Kolkata and eastern India, it carries genuine heritage weight. The challenge for Sonodyne in 2026 is the same as it’s always been: the consumer audio market is dominated by brands with massive marketing spend, and independent family-owned manufacturers need to find the right niche. Sonodyne’s strongest position is in professional audio installations where reputation, reliability, and service relationships matter more than advertising. That’s a narrower market but a more defensible one.
