Big Delhi celebrations — a sangeet rehearsal, a farmhouse get-together, a building Holi — need sound that reaches the back row. The PartyBox 330 delivers 280 watts: dual 6.5" woofers bring deep, chest-hitting bass while twin 25 mm PEN dome tweeters keep hooks sharp and harmonies clear, with a wider soundstage that pulls everyone into the mix — not just the front row.
AI Sound Boost + Smart EQ mode
AI Sound Boost reads your music in real time and predicts driver movement to max out bass and volume while minimising distortion — bigger, cleaner sound that stays punchy even at full volume. Smart EQ mode recognises whether the content is music or speech and adjusts the EQ automatically.
Adaptive futuristic lightshow
A lightshow that actually dances with you — sweeping ripple light trails and punchy strobes all sync to the beat, with a variety of patterns to match the lights to every mood. A refreshed top panel gives fast access to audio and light effects.
