BASS, DONE BETTER: INSIDE POLK
POWER PORT TECHNOLOGY
When it comes to experiencing the full impact of music and movies, deep, powerful bass is essential. It's what gives your favorite songs and scenes that deep, visceral punch, making them feel more immersive and engaging. But when it comes to designing speakers, achieving big, defined bass can be challenging.

One of the ways speaker manufacturers try to improve low-frequency output is by incorporating a port into the enclosure. This allows air to circulate freely in and out of the box, which relieves pressure inside the cabinet and improves the efficiency of the woofer action, resulting in louder, clearer bass.
However, these benefits come with side effects. When a ported speaker plays low frequencies, a lot of air flows through the port, creating turbulence that can introduce noise—often referred to as "chuffing"—and distortion. The tube-shaped port behaves like an organ pipe, creating resonances that can mask midrange sounds. And when a port is noisy, the energy used to produce that noise is no longer producing the intended sound: bass.
