Short answer: choose the Bose S1 Pro+ for a light, straightforward portable PA for speech or acoustic performance; choose the Electrotec Stage One for long outdoor events, very high endurance, and a broader set of event connections. The Bose is easier to carry at 6.5kg, while the Stage One is an 18.1kg battery PA designed around maximum runtime and flexible system use.
The Stage One is the more ambitious event speaker. Its dual removable batteries have a claimed 100-hour runtime, and it adds IPX6 protection, app EQ, USB playback, USB-A and USB-C charging, dual XLR/quarter-inch combo inputs, XLR output, and low-latency SKAA linking. Its 400W amplifier and measured 48Hz -10dB bass point give it more low-end and endurance potential than the Bose. The tradeoff is bulk, a focused PA presentation, and less suitability for relaxed living-room listening.
The Bose keeps the setup compact. It provides a three-channel mixer, two XLR or quarter-inch combo inputs, per-channel tone and reverb, Auto EQ for its placement angle, and optional docked wireless transmitters. Those controls are useful when one person needs to carry, place, and run a microphone or instrument without extra gear. It has only an 11-hour battery claim, no water resistance, and can distort with full-range music at high volume.
Buy the Electrotec Stage One for exceptionally long battery life, weather protection, USB media, system linking, and a more capable outdoor event platform.
Buy the Bose S1 Pro+ for the much lighter cabinet and an integrated mixer that keeps a simple solo setup easy.
Buy the Bose S1 Pro+ when the price outweighs sound quality for you, and the Electrotec Stage One when sound quality outweighs the price instead.
If battery life is a priority, the Electrotec Stage One is rated for 100 hours versus 11 hours for the Bose S1 Pro+.
If water resistance matters to you, the Electrotec Stage One at IPX6 (powerful water jets) holds up far better than the Bose S1 Pro+ at no water resistance.

The Two Speakers In Full
Bose S1 Pro+: $699.00 Amazon eBay
Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 XLR/quarter-inch combo mic-instrument + 1 line/Bluetooth), each with its own OLED display for quick treble/bass/reverb adjustment. Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode, plus a line out to daisy-chain a second unit. Optional WT-XLR/WT-INST wireless transmitters dock, pair, and charge right in the speaker for a cable-free mic or instrument. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage. Measured bass extension of 55Hz (-10dB).
Cons: With full range music, it becomes distorted above ⅔ volume, and reviewers describe it as screeching at max volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Ports are fully exposed with no water resistance. Charges via a less common three-prong AC cable instead of the two-prong barrel cable most rivals use.

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.
