This is the tale of finding discarded Marshall Uxbridge smart speakers in pristine condition, sparking curiosity and experimentation. Although initially impressed by their sound quality, the constant presence of the robotic voice was off-putting. The journey to de-smarten the speakers led to the decision to completely replace the electronics with custom-built active filter circuits and power amplifiers. Detailed schematics were provided, showcasing the design process and considerations, with a focus on achieving optimal audio quality. The final result was a unique, analog-driven stereo pair producing high-fidelity sound, a testament to ingenuity and dedication in the pursuit of sonic perfection.
