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 14.3 lbs (6.5 kg), while the Stage One is an 39.9 lbs (18.1 kg) 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.
