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 […]

Listening Position Measurements

Measurements at the listening position are nice to achieve a quick „objective“ sound quality documentation of an audio system. Let’s have a look at the basics. John Atkinson of Stereophile magazine keeps a certain procedure […]

Why could a bad speaker be measured as good at the listening position?

Well, as usual, easily asked and rather difficult to answer. What is a bad speaker and what would we measure at the listening position? These two questions are also relevant for providing an answer to […]
