These are not really the same size class, and that is the honest framing here. The JBL Partybox Stage 320 ranks #3 of 39 party speakers by sound quality at $499.95; the Electrotec Stage One ranks #2 of 14 battery-powered PA speakers by sound quality at $1450.
Short answer: the JBL Partybox Stage 320 edges it out, 4.6 against the Electrotec Stage One’s 4.2. The JBL Partybox Stage 320 stands out here: Handle and wheels are convenient. The Electrotec Stage One’s case starts with an exceptionally capable battery-powered PA: dual removable batteries deliver a claimed 100-hour runtime, and high-efficiency drivers deliver very high output with a measured 48Hz -10dB bass point.
Where they differ on paper:
- Battery Life: 18 hours (Manufacturer specified) vs 100 hours (Manufacturer specified)
- IP Rating: IPX4 vs IPX6
- Drivers: 2x 6.5” woofers, 2x 25mm tweeters vs Dual 1.5” compression drivers (tweeters) + 2x 4” woofers + passive radiators (PA system configuration)
- Amplifier Power: 240W vs 400W
The JBL Partybox Stage 320’s argument: Handle and wheels are convenient. Watch for: slightly sibilant in the treble at full blast. It’s cheaper as well, $499.95 against $1450.
Go with the Electrotec Stage One for an exceptionally capable battery-powered PA: Watch for: it prioritizes maximum output and endurance over truly deep bass, so it will not replace a dedicated subwoofer for low-frequency-heavy music. It’s also the more expensive option, $1450 against $499.95.
Buy the JBL Partybox Stage 320 at $499.95 if you want a party speaker. Buy the Electrotec Stage One at $1450 if you want a battery-powered PA speaker instead.

Electrotec Stage One: $1450 Electrotec Audio eBay
Pros: An exceptionally capable battery-powered PA: dual removable batteries deliver a claimed 100-hour runtime, and high-efficiency drivers deliver very high output with a measured 48Hz -10dB bass point. It adds app EQ, IPX6 protection, mic and XLR inputs/outputs, USB playback and low-latency SKAA linking, making it unusually flexible for events and performers. Measured bass extension of 48Hz (-10dB).
Cons: It prioritizes maximum output and endurance over truly deep bass, so it will not replace a dedicated subwoofer for low-frequency-heavy music. At 18.1kg it is a substantial carry, and its focused PA-style presentation is less suitable for wide, relaxed living-room listening.
