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 […]

Music, Loudspeakers and Measurements

I remember the moment when, late in childhood, after about 10 years of piano playing, I made a decision. After hearing a very impressive piano player I thought I would never be in that league. […]

More listening to music played out loud – More sex!

It sounds a bit superstitious “more listening to music played out loud – more sex”. Germany ranks in the list of superstitious countries pretty low. But there is this one habit when raising a glass to […]

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 […]

LS Measurements at various distances

I would like to continue from last time, discussing measured data at various distances. Including some nearfield effects. Loudspeaker, room and placement remain the same, the time response has been shown last time. For some […]
