Phase and Time 1

 Listen to the blog: Phase and Time 1 While certain crossover configurations let tweeter (HF) and woofer (LF) radiate in phase with each other, this does not mean they radiate at the same time. Motivated by […]

Loudspeaker Phase Response

 Text to speech – TestHiFi Blog: Loudspeaker Phase Response Loudspeakers usually radiate different frequencies with different phase. This is due to the drivers themselves, interaction with the cabinet, and the crossover. A basic example of phase […]
