lower nonlinear distortion and significantly improved sound quality in the lower frequencies

thus greatly eliminating large dynamic distortion and ensuring more stable high quality

The precise 3D printed acoustic filter nozzle structure is used for frequency division

the Blessing 3 doubles the maximum sound pressure output compared to the previous model
