Why sound deadening matters in the 2023+ Prius
Without a dedicated air baffle, sound waves from your door speakers bounce around inside the door cavity, cancelling each other out before they reach your ears. The result is weak bass, muddy mids, and a generally thin sound that no amplifier or speaker upgrade can fully solve on its own. The DMS-T305 seals that cavity, forces the speaker's output forward toward the listener, and eliminates the wave cancellation that robs your system of its full potential - all without touching a single piece of factory wiring or waterproofing.
