A farmhouse lawn in Chhatarpur, a terrace in Rajouri Garden, a sangeet in a banquet driveway — outdoors, sound has nothing to bounce off. There are no walls to reinforce the bass, so a small speaker that sounds loud in a bedroom simply disappears once the crowd and the open air take over. The Stage 320 answers that with 240 watts driving two 6.5″ woofers and two 25mm dome tweeters — enough clean, deep, undistorted output to fill a space the size of a tennis court, indoors or out. The dual woofers split the bass work between them, so the low end stays tight and controlled at the volume everyone actually wants it at.
AI Sound Boost — the speaker tunes itself to the room and the volume
The same playlist behaves completely differently on a closed terrace at 11 PM and on an open lawn at full volume. AI Sound Boost is JBL's adaptive processing: it reads the audio signal and the acoustic environment continuously and adjusts the output in real time, rather than applying one fixed equaliser curve to everything. In practice that means the bass stays present and the vocals stay intelligible whether you are running background music during dinner or pushing the system hard once the dancing starts — and it protects the drivers by managing dynamics before they are pushed past their limits. You set the volume; the speaker handles the rest.
Telescopic handle, wide wheels, IPX4 — 16.5 kg that moves like cabin luggage
At 38.5 × 33.5 × 66.9 cm and 16.5 kg, this is a floor-standing speaker with real drivers inside it. The telescopic handle and wide wheels are what make that practical: tip it back and roll it out of the storeroom, across the lawn, over gravel and up to the car, exactly the way you move a wheeled suitcase — the wheels carry the weight instead of your back. The handle collapses away once the speaker is standing where you want it. IPX4 splash resistance covers it for outdoor use, so an unexpected monsoon shower over a Delhi terrace party or a drink knocked over near the grille is handled and the evening carries on.
🔋 Three ways to keep it playing all night
18 Hours
A full charge runs from the evening setup through to sunrise
10-Min Fast Charge
Ten minutes on the mains buys two more hours of playtime
Swappable Battery
Slot in a charged spare, available separately, and keep going
Mains Playback
Plug the power cable in for uninterrupted running at a fixed venue
🎤 A live-performance rig built into the speaker
Dual Mic Inputs
Two microphones at once — a duet, or an MC alongside a singer
Karaoke EQ
Vocal-tuned processing on the mic channel, separate from the music
Guitar Input
Plug a guitar straight in and play live over a backing track
PartyBox App
Sound, lightshow and playback controlled from your phone
🛠️ Built into the Stage 320
The lightshow reads the beat of whatever is playing and syncs the starry patterns, trails and strobes to it — and the JBL PartyBox app lets you dial the lighting separately from the sound, so a family function and a late-night set get different atmospheres from the same box.
Two 6.5″ woofers deliver clean, precise, deep bass even at top volume while two 25mm dome tweeters keep the highs crystal clear — the reason it stays composed at the volumes an outdoor crowd needs.
Starry lights, cool light trails and strobe effects, all synced to your beat. The room changes character the moment it starts — the difference between music playing and an event happening.
Two mic inputs with Karaoke EQ and a dedicated guitar input turn the speaker into a complete performance system — antakshari at a family function, a live guitarist at a terrace evening, an MC at a wedding.
Dusk-till-dawn playback on one charge, a ten-minute top-up worth two extra hours when a Delhi power cut eats into your setup time, and a swappable battery available separately for back-to-back events.
