The Brioso Speakers - Lively Two-Way Speakers With Transmission-Line Bass
The Brioso uses a Scan-Speak Revelator midwoofer and a Transducer Labs Alumina ceramic dome tweeter in a floor-standing, mass-loaded transmission-line (ML-TL) enclosure. Paul won first place for this design in the over-$200 category in the 2017 Midwest Audiofest (MWAF) event held by Parts Express.
Miking Solo Voices And Instruments- The Mic Choices
Although there are many microphones, from which to choose, you need to consider several important acoustical factors to obtain good results.
The Challenges Of Live Recordings
Making a high-quality audio recording in a recording studio is one thing, but making a similar recording at a live concert has its own challenges. Neville Roberts flies out to Venice, Italy, to investigate.
Comsol Multiphysics Acoustics Module
Making the Case for Acoustic Modeling and Simulation Apps
Acoustics In Performance
In this book, Richard Honeycutt details “all you need to know about good acoustics and sound systems in performance and worship spaces.” audioXpress and Voice Coil readers will be familiar with Richard A. Honeycutt’s writings, including audioXpress’ Hollow- State Electronics column, dedicated to exploring all tube-related electronics, and his Sound Control column, dedicated to everything in acoustics. Richard has also contributed to Voice Coil since 1994, so the author knows his subject matter.
Schiit Audio's High-Value Ideas
Unless you’ve been away from hi-fi for the past few years, you’ve probably heard of Schiit Audio, a high-value brand available at reasonable prices. Over the years, Schiit Audio owner Jason Stoddard and I have talked at trade shows and I recently caught up with Jason to talk about his company.
DIY Tube Amplifier Heat Management Options
The objective of this article is to illustrate some methods to greatly increase the performance and reliability of your DIY tube amplifier. I’m only discussing DIY tube amplifiers since they generate the most heat per watt of audio output and are hopefully of the most interest to you. Most designs that I have seen in audioXpress have the tube and the transformers on top of the chassis and everything else under the chassis. Most of the amplifiers look nice and work okay, but I think there is a better way!
Thoughts On AES X223 And X241 Speaker Measurement Projects
I have just returned from the recent Audio Engineering Society (AES) 144th International Convention in Milan, Italy, where I was among many colleagues who are trying to solve one of the outstanding problems of loudspeaker drive units today. Namely, being able to trust the measurements that are being presented to us.
Sonarworks Reference 4 Studio Edition- Loudspeaker And Headphone Correction System
Stuart Yaniger takes a look at Sonarworks, a relatively new entry into this market and its main offering—the Reference 4 Studio Edition, which is clearly targeted to studio and mastering use but can certainly be used in home audio setups.
