Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Stage 320 ranks #3 of 51 party speakers by sound quality at $499.95; the JBL Partybox Ultimate ranks #3 of 13 large party speakers by sound quality at $1,499.95.
The JBL Partybox Stage 320 is the battery-powered, lighter pick. An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. Its battery is rated for 18 hours, while the JBL Partybox Ultimate needs an outlet. At 36.4 lbs (16.5 kg) it weighs much less than the JBL Partybox Ultimate at 86 lbs (39 kg). Watch for: Slightly sibilant in the treble at full blast.
What the JBL Partybox Ultimate does well: A huge party speaker with deep, powerful bass and clear sound at extreme volume, plus Wi-Fi and karaoke inputs. Watch for: At 86 lbs (39 kg) and more than a metre tall, this is not casually portable despite the wheels.
Buy the JBL Partybox Stage 320 ($499.95) for a party speaker; the JBL Partybox Ultimate ($1,499.95) suits a large party speaker instead.
