Loudspeaker Legends – Yamaha NS10M and Modifications
The Yamaha NS10M can be seen on the meterbridge in many studios.While they were discontinued years ago, many are still in use.One reason may be that they sound quite forward, with good insighton recording or […]
Complex bass array – Plattenwerk.at
In my last TestHiFi blog I wrote about a band-limited low frequency (LF) system to fill a response gap. This time I would like to show a much more complex LF system. Some years ago […]
An unconventional loudspeaker solution for LEWITT Audio
An unconventional low frequency solution – LEWITT Audio The result
shows the advantage of this remarkable space: walking back along the symmetry axis towards the rear wall without any change of LF characteristics. Nice and even everywhere!
LF reproduction can be tricky, even in an amazing room like this. One more reason for custom design 🙂
The Sound of Tubes ?
At TestHiFi we discuss and develop ways to measure aspects of music reproduction. Sometimes, working on my own loudspeaker projects, such aspects draw attention. About such an event I want to write this time. When […]
Woofer Size
Why woofers need to be large to radiate efficiently Due to a recent discussion about efficiency and directivity: Is higher efficiency – like with horn systems – a result of higher directivity? Produced by restricting […]
Phase and Time 3
Text to speech – TestHiFi blog: Phase and Time 3 Phase and Time – Time Domain Response, Step Response In my first blog „Phase and Time 1“ I focused on amplitude and phase shown as […]
Phase and Time 2
Text to speech – TestHiFi blog: Phase and Time 2 The system that shouldn’t work well – phase and time completely ignored! Last time I wrote about phase and time issues of loudspeakers. A result […]
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 […]
Loudspeakers and Single Ended Tube Amplifiers
Text to speech – TestHiFi Blog: Loudspeakers and Single Ended Tube Amplifiers What are SETs? Short for Single Ended Tube, or more specific, Triode Amplifier. My favorite kind of amplification! The inherent problem of those […]
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. […]
