A Step Toward Real-World Education
Product Development: Learning From Experts
As I've previously written, I strongly believe that a magazine and content publisher, should stick to what it does well. That means staying away from event and trade-show production. On the other hand, magazines are perfect partners for professional associations and trade show promoters. And education- and industry-focused entities such as the Audio Engineering Society (AES), ALTI, AVIXA, CEDIA, and many others, are perfect partners for publications such as audioXpress.

Specifically with the AES, audioXpress has long been involved in many of its conference tracks and constantly helping to promote the association's activities. Among the many AES activities in recent years, we felt that audioXpress would be the ideal partner and should be involved with many of its technical tracks, and particularly with the Audio Builders Workshop and the Product Development Track. There's a clear synergy, and many of the experts who write for our magazine - and supporting companies - are also participants there.

The circumstances completely changed in 2020 with the global pandemic and the traveling restrictions, completely canceling traditional activities with in-person events. Precisely at this time of the year we expected to be preparing to go to New York and enjoy another intense and always rewarding International AES Convention, one of the very few shows where audioXpress (and it's sister publications from KCK Media Corp.) actually have a booth every year. Still, our stance regarding our strategic cooperation with industry associations stays the same, and we think it is more important than ever to work together on different initiatives and reinforce our cooperation.

In the aftermath of last year's New York AES convention, and shortly after the announcement of the COVID-19 pandemic, I was asked to get involved with the Audio Product Education Institute (APEI), a new initiative of the AES to focus on promoting methodologies, practices, and technologies involved in developing and bringing audio products to market. With a clear education focus, this is totally complementary to what we do in audioXpress.

The Institute's roadmap also intends to focus on six educational pillars, starting with Interactive Voice and DSP, a key technology area where audioXpress has been focused for more than five years; Supply Chain and Sourcing, an area that reflects extremely well the experience of our own team; Modeling and Measurement, another strong area of focus for our technical content; Product Management, one of my favorite topics, on par with my personal marketing management interests; Automotive Audio, a discipline that we started to cover since it got actually interesting; and finally Artificial Intelligence and Machine Learning, an emerging area that audioXpress has also been exploring for the past few years.

As the first organization focused entirely on Audio Product Development Education, APEI is not restricted to any particular product class or market segment area, is strongly oriented toward innovative and growing segments, and aims to bring "Real World, Hands-On Education" to the industry. Leading the APEI effort, is Scott Leslie, the AES Product Development Track chair since its inception in 2014 (at the 141st AES International Convention in Los Angeles, CA), and a professional with extensive experience in engineering/management roles at Altec, JBL, and many other leading audio companies. The Product Development Track grew in popularity from there and has been part of the annual AES International Conventions each year.

Scott Leslie is now APEI's Managing Director and is building a team of product professionals to expand the institute's capabilities and reach. For now, APEI is focusing primarily on online events, but it aims to promote in-person deep education events for each education pillar, offer brand/manufacturer specific training, build a Resource Library, and promote a product development professionals network and career resource.

As he explains: "The dramatic increase in audio products and their demand beginning with the Bluetooth speakers and now the smart speaker category has created a huge increase in the demand for development professionals in this market. Universities are teaching strong fundamentals but little audio specific or hands-on development skills needed to advance these new team members at the rate they need to to contribute at a high level. Many seasoned professionals from other product areas are also entering the audio world and need audio-specific training and best practices. It became clear the demand for skilled product professionals is greatly exceeding the available education needed to support them." 

"In order to better address the huge growth in audio products and the companies developing these products, the Audio Product Education Institute was formed as the next logical progression toward serving the AES Product Development Track audience. Audio products today span a wide range of applications across consumer, automotive and commercial sectors. Overall the audio products market represents approximately $100 billion in revenue. With the huge growth in recent years, comes the challenges of training and keeping product professionals current on the best science, technology, economics, and supply chain and management methods and practices. Audio product companies worldwide today cannot hire and train people at the rate required by the demand for their products. APEI's mission is to serve this need," he adds.

As the October AES event was forced to move entirely online, the association also decided to provide an expansive program during the entire month of October. The Product Development Track was replaced by the APEI Product Development Symposium happening October 14, 15, and 16. Each day, multiple experts from the different educational pillars will provide a variety of presentations. The detailed schedule is now online.

Audio Product Development is precisely what audioXpress promotes daily, weekly, and monthly online, with our newsletter The Audio Voice and in the magazine. These activities fit right into our core audience's interests and that is why audioXpress is the proud Official Media Partner for APEI and specifically for this Product Development Symposium.

audioXpress already focuses on the topics about which audio developers care and we serve the people who daily provide the research on which the audio industry evolves. The AES Product Development Symposium's sessions will be chaired and presented by experienced audio product professionals who are experts in each field, and understand what it takes to launch successful audio products. Acoustics, electronics, DSP, software engineering, and product and marketing management will all be addressed through a real-world perspective.

We highly recommend this event, part of the October online events of AES Show Fall 2020. All Access registration is required to attend the Product Development Symposium, available now at

Until we can all get together again, in person, this is the best we can do.

The LD25X High-End Tweeter from Creative Sound Solutions
By Vance Dickason
This Test Bench article addresses an interesting home audio tweeter from Creative Sound Solutions (CSS). CSS Audio was founded in 2001 and is operated out of the Southeast Michigan area by two friends with a passion for great audio. Ownership of CSS was transferred from Bob Reimer, the original founder, to Kerry Armes and Dan Pointsett in 2017 and they've been working on bringing back some of the drivers CSS is known for, like its high Xmax XBL dual gap woofers, which are still part of CSS OEM lineup. The company designs its own line of OEM woofers and tweeters, which it also uses to manufacture complete speakers and speaker kits branded under the CSS name. CSS sent Voice Coil its latest high-end tweeter, the LD25X, a special driver with a unique dual-gap patented XBL2 motor. CSS licenses the XBL2 technology from inventor Dan Wiggins for two of their woofers and for the LD25X tweeter. The XBL2 motor features a short voice coil traveling between two gaps, allowing for a higher Xmax than most conventional motors can provide. The LD25X tweeter features a 25mm silk dome diaphragm and flat silk surround, in a 73 mm diameter six screw cast-aluminum faceplate anodized semi-flat black.
