What’s the Difference Between Bipole and Dipole?

A dipole goes one step further, making the sound from the two sets of drivers “out of phase.” What happens is this: As a speaker driver on one side or baffle moves outward to fire sound, its companion on the opposite side moves inward. Any opposing bass waves cancel themselves out at the sides of the speaker (similar to what happens in noise-cancellation headphones), and the higher and midrange sounds are dispersed throughout the room, creating an even more ambient quality. Dipole speakers are often used in higher-end home theaters, so consult with a professional if you’re thinking of using them.
