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 Electrotec Stage One ranks #2 of 17 battery-powered PA speakers by sound quality at $1,450.
What the JBL Partybox Stage 320 does well: An excellent sounding party speaker, with deep bass that holds up at high volume, wheels, a removable battery and mic inputs. Watch for: Slightly sibilant in the treble at full blast.
The Electrotec Stage One is the longer-running, tougher choice. A battery PA speaker with very high output, a claimed 100 hour battery and weather resistance, built for events. It is rated for 100 hours of battery against 18 for the JBL Partybox Stage 320. It is rated IPX6 against IPX4 for the JBL Partybox Stage 320. The tradeoff: It prioritizes maximum output and endurance over truly deep bass, so it will not replace a dedicated subwoofer for low-frequency-heavy music.
Buy the JBL Partybox Stage 320 at $499.95 if you want a party speaker. Buy the Electrotec Stage One at $1,450 if you want a battery-powered PA speaker instead.
