Why Are We Doing This?

And then three becomes one!
About this time 16 years ago, Ed Dell made an announcement in Audio Electronics, Speaker Builder, and Glass Audio magazines to signal the transition to a new monthly title, called audioXpress. His letter was titled "Why We Are Doing This," and I thought it would be interesting to share what the magazine's founder said back then:
My friends,
Just over 30 years ago we set out on a journey into publishing a magazine about audio construction with high hopes and not a little apprehension. I feel that we are at a very similar threshold here in the last quarter of 2000. I am very pleased to announce the launch of a brand new periodical, audioXpress, whose first edition will mail to you in late December.
audioXpress will combine Audio Electronics, Glass Audio, and Speaker Builder in a monthly magazine.
(...) We believe it will strengthen our effort to offer you a magazine about audio design and construction which will be larger and more powerful. It will increase the effectiveness of advertisers' investment in ad space. It will, we believe, attract some advertisers who have never been interested in our smaller-sized periodicals. (...) It will give us space to expand our reviews of all kinds of equipment, which broadens our coverage of the audio field. Since we have wanted to offer more reviews, the broader platform of audioXpress will more naturally accommodate the entire audio chain.
(...) We hope that a combination of technologies will make it easier to deal with complete systems of components and the ways these interact with each other.
(...) We hope you will continue to trust us to do our very best for all of your needs for audio technology information.

As Linkedin reminded me last week, it has been 3 years since I joined audioXpress, and I received so many heartwarming messages, I've looked at these words as a way also to remind myself of why are we doing this. I think the answer is clear when we see how audioXpress has evolved, and we look at the current pages of the magazine, as well as our online presence (
As I've repeatedly stated, our updated mission now includes being the reference information source about innovative solutions and technologies in audio electronics, acoustic and electro-acoustic design for DIY audio enthusiasts, audio product designers, electronic engineers and audio engineers. Increasingly, we are combining information for audio product development and design, as we are about construction.
For the next months, we are working hard on getting our objective review program in place and expanding the coverage topics to more cutting-edge technologies and domains, from embedded systems and silicon solutions to digital audio processing, software and acoustics.
This is also a perfect opportunity to appeal to anyone interested in contributing articles. audioXpress is looking at more expert contributions in the mentioned areas as well as more DIY projects. audioXpress is also interested in sharing your engineering and R&D stories.
Feel free to contact me with ideas and suggestions.

Factory Tour
Sinar Baja Electric:
Too Big to Be Kept a Secret
By Joćo Martins
In audioXpress July 2016 we published a complete Factory Tour report on Sinar Baja Electric - the birthplace of speaker driver brand SB Acoustics - where we reveal the usually hidden perspective of speaker manufacturing, from design concept to finished products. There's an exaggerated notion that everything is made in China these days, but the story of this Indonesian company with its own dedicated design team in Denmark, serves to show how truly global the industry really is.
Sinar Baja Electric is a complete speaker manufacturer facility, a group of vertically integrated companies serving an impressive number of OEM companies all over the world. audioXpress visited the company in Surabaya, Indonesia, to see how it intends to convert its SB Acoustics speaker driver brand into a worldwide reference, designed in Denmark, manufactured in Indonesia.

Voice Coil Test Bench
MAG Audio M0610 Midrange Driver 
By Vance Dickason
This submission comes from a company new to Test Bench, MAG Audio, from Ukraine. MAG Audio is the biggest producer of professional transducers and loudspeaker systems in Ukraine. Founded in 1991, the company designs and manufactures high-quality reliable world-class loudspeaker systems adopted in Ukraine and around the world. The company's primary products were ferrite magnets, which MAG continues to produce. MAG Audio's transducers now include a complete range of cone loudspeakers with sizes from 6" to 21", plus 1", 1.4", 1.5" and 2" high-frequency drivers and coaxial drivers. MAG currently has 120 employees and a 30,000 ft2 production facility. About 60% of MAG's production is exported. The sample pro sound midrange driver MAG submitted is one of my favorite formats. The M0610's features include a cast-aluminum frame, a lightweight curved profile uncoated paper cone, a 2" diameter uncoated paper dust cap, and a 1.5" (38-mm) diameter voice coil wound on a Kapton former with edge wound copper-clad aluminum ribbon wire. Compliance is provided by a flat foam surround and a 4.5" diameter flat cloth spider. A 110-mm × 15-mm detachable self-centering strontium ferrite magnet with a black coated back plate powers the unit. Last, the voice coil tinsel lead wires terminate to a standard pair of solderable terminals. This article was originally published in Voice Coil, November 2013.  Read the Full Article Online
