These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 51 party speakers by sound quality at $499.95; the JBL Partybox 520 ranks #8 of 13 large party speakers by sound quality at $879.95.
The JBL Partybox Stage 320 is the lighter choice. An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. At 36.4 lbs (16.5 kg) it weighs noticeably less than the JBL Partybox 520 at 56.2 lbs (25.5 kg). The tradeoff: Slightly sibilant in the treble at full blast.
Why pick the JBL Partybox 520: A loud battery party speaker with deep bass, wheels, a capable app EQ, and inputs for mics and instruments. Watch for: It is very large and heavy, Bluetooth latency is high for video, and its front-facing design loses much of the mids and treble to people off to the sides.
Buy the JBL Partybox Stage 320 at $499.95 for a party speaker, or the JBL Partybox 520 at $879.95 for a large party speaker instead.
