Audio Industry Returns to Trade Shows
ALTI Expo 2022 and the Return of the ALMA Awards
As I’ve been warning, trade shows are just too important to miss. As predicted, we’ve never seen so many photos of people “getting back to business” on social media as this week. It’s absolutely crazy, because there are overlapping trade shows of all sorts - and no one seems to care. While some of the most prestigious and important trade shows have opened their doors once again, some after three years of absence (the April shows, which happened last in 2019), some countries are also promoting their own regional events, sometimes serving precisely the same industries as the shows happening in Las Vegas, NV, or Frankfurt, Germany. And no one cares, basically because people are just excited to attend events and actually meet their friends, colleagues, and clients - the business will come naturally as a result (let’s just hope the virus doesn’t).

Announcements were not that numerous - most companies anticipated the rush and wisely opted to make their product unveils in advance. That way it didn’t matter if shows where well attended or not, the focus remains on reconnecting with people first.
The weather was beautiful in Las Vegas, NV, for NAB 2022, and the industry was just overjoyed to meet again at a trade show. The National Association of Broadcasters (NAB) reported a preliminary registered attendance of 52,468, with 11,500 international visitors.
That’s what I heard from my colleagues who attended NAB 2022 in Las Vegas this week, and don’t even remember how the exhibits were, or who launched what. They were all just too tired from all the parties and social activities that took place - some even during show hours! Apparently, there were as many people with NAB show badges walking the town, as there were at the LVCC. And while there, many took consecutive rides on the underground loop between halls, just in order to shoot better videos of the Tesla's ride to share. Some magazines were even struggling to deliver their pretend best-of-show awards since it was harder to find the CEO or marketing teams to take the mandatory show floor shots. It didn’t matter, everyone was just happy to be there again.

And that’s what I hear from our team currently in Frankfurt for Prolight+Sound. Everyone is mainly happy that the show could be held again. The Frankfurt Messe organization tried hard, there is an extensive conference program, great demonstrations, and more visitors than expected - and those who attend are simply happy to see each other again.

As our colleague Ward Maas reports, at this show the mood is not as optimistic, exhibits in the audio section are not many and certainly not as big as the ones in the stage and show lighting hall. “Certain market segments, such as pro audio and live sound, were hit hard by COVID. No concerts, no festivals. As a result, less money available for investments, but also less money available to have a large presence at this show. And for many brands, it was simply too much to ask to attend both Prolight+Sound and ISE in Barcelona, two weeks later. So choices had to be made.

But for those who attended Prolight+Sound, the return is possible, as he confirms. “Business depends mainly on what is available for the festival season given the material shortages and supply problems. Those who can deliver, sell, and visitors have their shopping lists in hand. The organizers are paying attention. Perhaps it would be a good idea to attend next year.
Prolight+Sound 2022 is ongoing and attendance is larger than expected for the size of the show, which was crushed by the overlapping post-pandemic trade show schedule. Next year will be better.
A less euphoric version of this return-to-trade-shows spirit was the unique environment of AXPONA 2022, which is more product-focused than any other show, and probably the only show in the world this year where people reconnecting after two years or more simply wave at each other without saying a word — in order not to disturb the ongoing listening sessions. As Oliver Masciarotte reported, “Everyone, whether dealer, manufacturer, or attendee was as stoked as I to be at a flesh-and-blood gathering. After all, the whole point of a hi-fi show is to hear the differences that each system brings. Zoom simply cannot convey that nuance.

An unintended consequence of people getting used to relying on being online for everything is that the trust on streaming media is now greater than ever. And at AXPONA that was clearly visible, as Oliver noted. “I was struck by how exhibitors at the biggest hi-fi show have embraced Qobuz. AXPONA 2022 was the first show I have covered where I carried no CDs, no SACDs, and no flash drives. I pre-selected a handful of songs to use as my test material, and Qobuz supplied the content.” Anyway, he is writing a first-impressions article for our newsletter next week, so more on that later.
Some images from AXPONA 2022, shamefully grabbed from exhibitors’ social media pages (including Warwick and Pro Audio Design), showing different perspectives of an event where at least the main focus is on listening again. Anyway, there was time to party, after show hours.
ALTI Expo 2022
For this week, I had intended to write instead about an important upcoming in-person event that deserves attention from our audience and that also risks being squeezed by this trade-show rush and overlapping schedules. I’m talking about ALTI Expo 2022, the conference promoted by the Audio & Loudspeaker Technologies International (ALTI) Association, which is also right around the corner, set for June 5–6 at the South Point Hotel and Casino in Las Vegas, NV.

Our readers might not be familiar with ALTI and much less with ALTI Expo, but that is perfectly normal considering the association used to be called ALMA, and changed the name in the year before the global pandemic - here is an article about those changes. Read the full audioXpress report available for a refresh of the previous ALTI Expo in 2019 - now seemingly distant events.

ALTI is the association with which audio manufacturers, developers, and all the technical folks who make audio products need to be connected. And since it moved away from CES, its excellent annual event now takes place just a few days before the InfoComm show in Las Vegas (Education, June 4-10 - Exhibits, June 8-10). What was not expected is that the Winter NAMM Show this year would take place in June as well. But it will (June 3-5). The full story is here but it’s important to note a few things. That show is only three days this year, and yes, the third day overlaps with ALTI Expo in Vegas, which means we only have two days to attend NAMM, and we will need to rush off to the South Point Hotel and Casino in Las Vegas, where ALTI Expo takes place.
Time to plan how to attend this year’s ALTI Expo and Conference at the South Point Hotel and Casino in Las Vegas, NV, June 5–6, just prior to InfoComm. Leave earlier from NAMM if you attend, it will be important.
ALTI continues to be the only international trade association dedicated to improving the design and manufacture of loudspeakers and related technologies. But its scope expanded to reflect the whole audio industry ecosystem. This means that its role is now even more crucial to the industry, and many industry folks who usually don’t even attend NAMM or InfoComm have a reason to be there. And reflecting the association’s expanded scope, this year’s keynote presentation will be delivered by Andrew Bellavia, Director of Market Development at Knowles Electronics, who will explain why the “golden age of audio” is happening now.

And yes, there’s many reasons to attend, including to support ALTI’s Incubator program for new companies and inventors; the Speaker Builders Workshop; and presentations by experts from Klippel, Listen, Composite Sound, Audio Precision, HEAD acoustics, NTi Audio, Parts Express, and many more. There will be also an interesting presentation on Supply Chain issues by Rosemary Coates and others, and ALTI is already working to identify the issues and explore solutions. To support the session content, ALTI is promoting a brief 10 question survey - available here https://www.surveymonkey.com/r/S3LZSVN. The results will be explored and discussed at ALTI-Expo. Survey results will also be available to all who participate in the survey.

So, please make an effort to support the association’s initiatives and plan to attend this year’s ALTI Expo and Conference at the South Point Hotel and Casino in Las Vegas, NV, June 5–6, just prior to the InfoComm Show. The South Point hotel still offers affordable accommodation for those attending, so everyone can just focus on the event.

ALTI Expo 2022 offers two days of outstanding technical and business content. There are many opportunities for networking and spending quality time with exhibitors and attendees, and a great focus on getting business done! There’s even a banquet and the celebration once again of the prestigious ALMA Awards, highlighting outstanding products, people, and technologies in the audio industry (yes the awards remain connected to the original name, in respect to all those who received one in the past — and also because ALMA is a great name for an award!)

ALTI’s ALMA Awards honor the Association’s heritage as well as excellence and achievement with five award categories: Lifetime Achievement, Technology Achievement, Industry Contribution, Innovation Award, and ALTI Member Award.

audioXpress and Voice Coil magazines are the official media partners for ALTI Expo and will be directly supporting the ALMA Awards once again. Stay tuned for more information, coming soon. More information about ALTI Expo 2022 is available here: https://altiassoc.org/alti-expo-22/
The ALMA Awards are back and are always an important aspect of ALTI association’s efforts, this year promoted with direct support from audioXpress and Voice Coil.

Wavecor WF275BD01 10.75” Home Audio Woofer
By Vance Dickason
The latest WF275BD01 10.75” woofer from Wavecor is a new high-power design targeting home audio and home theater applications, including two-way (with larger ribbon/AMT drivers, or compression driver/horn combinations) and three-way speakers. Part of a new series of drivers announced in October 2020 by Wavecor, this woofer could also be advantageous in high-powered studio monitors. The feature set for the WF275BD01 is like most high-performance two-channel/home theater drivers, fairly substantial. Starting with the frame, the WF275BD01 uses a proprietary eight-spoke cast-aluminum frame incorporating rectangular vent holes in the area below the spider mounting shelf for enhanced voice coil cooling. This series of cooling vents allows air to move past the voice coil and across the front side of the ferrite motor assembly.
