How we ranked these pa speakers
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: pa speaker for keyboard
Start with the mixer inputs
A keyboard needs a line-level input, and the mixers here differ. The ALTO TS408 has a 3-channel mixer with dual XLR/1/4-inch combo inputs and mic/line switches. The PRORECK Party 8 has an 8-channel mixer with 4 independent XLR mic/line channels, plus 6.35mm and RCA inputs for keyboards. The Bose S1 Pro+ has a 3-channel mixer with two channels for microphones and instruments.
Weigh power against portability
Watts and weight pull in opposite directions here. The ALTO TS408 offers 2000W at 20.7 lb, the PRORECK Party 8 offers 600W at 45 lb, and the Bose S1 Pro+ offers 150W at 14.4 lb with a battery that runs up to 11 hours. The Bose is the Lightest Pick for carrying, while the ALTO has the highest wattage of the three.
