CEDIA 2019 Show Report
Residential Integration in the Age
of the Connected Home 

While I visited the exhibits at the excellent Colorado Convention Center during the 2019 CEDIA Expo in Denver, I was frequently asked about my impressions of the show - but often it was as if people were asking me to validate their own negative impressions - because "this industry has seen better days...", and "the show is smaller than ever." I saw the show in a different perspective, which I will address in this report. 

Colorado Convention Center, Denver. A great home for CEDIA Expo.

The CEDIA Expo is now operated by Emerald Expositions, since CEDIA - the association - decided to sell that part of their activity to a professional trade show organizer three years ago. And it's true, this coincided with a challenging transition period for both the association and the industry, as the market segment expanded its scope to embrace the connected home, adding security, home automation, and networking, and CEDIA also focused its efforts on expanding its related training and certification activities. As if to compensate for the criticism of the previous two editions, Emerald seems to have learned its lessons and the 2019 CEDIA Expo was a smooth, well-attended, and extremely well-organized event. 

Yes, that big area where Crestron used to be is missing since 2016, and there were less companies exhibiting, mostly as a direct result of recent mergers and acquisitions. But the fact is, the CEDIA Expo visitors' profile remains highly focused on integrators, who are those professionals who have the knowledge and expertise to design, specify, and build home systems. And Crestron has in fact been replaced at the show by new players in the home systems space, including Google, Amazon, Sonos, and others.

CEDIA is the Custom Electronic Design & Installation Association and, as the association states, CEDIA members are "the industry most trusted home technology partners."  Notice that reference to "home technology."

As Futuresource Consulting reported, the uptake of smart home devices continues apace and is on track to ship 137 million units in 2019, worth $16 billion in trade value. That represents a 37% volume increase on 2018, with a slowdown in home hub sales being eclipsed by accelerating growth in other categories.


When one visits the CEDIA Expo, the dominant theme is audio, by far, followed by lighting and some display companies - essentially, Samsung, LG Electronics, and Sony - which are also active in other products categories, such as projectors and audio systems.

When one thinks about home technology, today we think about home automation or what people like to call these days, smart home solutions. The problem is, when there's a reference to "smart home," people essentially think about Google and Amazon ecosystems and, increasingly, voice control. Underlying the topic, there's also Apple's HomeKit concept, which like all things Apple, is omnipresent at shows like this (you don't actually see a booth, but it's everywhere).

Anyway, CEDIA reflects the robust residential integration network of vendors, distributors, and service providers, which in itself is one of strongest market networks, working in sync to provide the best solutions for the home. It is structured upon an extensive network of regional and local retailers, supported by hyperlocal installation providers and service professionals. Not many industries have such an extensive and highly specialized structure - sharing in many aspects the intricate and highly specialized electric power and HVAC installation network that thrives upon the home building and renovation opportunities.

So, any suggestion that the residential integration industry might be in contraction or decline is just wrong. What is happening, like in many other industries, is just that the network itself is adjusting to the wider scope of opportunities allowed by the connected home, while other companies and professionals opt to specialize in certain product segments - home theater being one of those - while broadening their business opportunities in distribution and installation.

Like many other application segments, this is also an industry feeling the effects of technology changes, amplified by a disruption caused by the large players such as Amazon, Google, and others - which in fact would like to work as much as possible with the residential integration industry, not destroy it.

Google's presence at CEDIA Expo 2019 was strong and the residential integration industry is trying to leverage the opportunities.

The situation is similar to what is happening in the commercial systems integration sector, reflected by shows such as InfoComm, which is promoted by an association that primarily reflects the perspective of "pro AV technology" vendors (the association was recently renamed as The AudioVisual And Integrated Experience Association - AVIXA), when in fact the activities of many of its members - and certainly the professionals that attend its trade show - cover the whole systems integration industry. That is, all the systems and technologies that are needed inside offices, buildings, or public spaces following the construction infrastructure - and AV is just a fraction of that.

The market represented by CEDIA entails all the systems that fit inside the home, which require a different set of skills and marketing strategies when dealing with home owners and families, not complex organizations like in the commercial sector. Residential integration needs to embrace and expand into a wider range of technologies, from lightning and comfort automation (companies such as Lutron and Legrand seem to fully understand that...), and also needs a better understanding of new disciplines like home security, connected locks, and home communications. That is precisely what Google is promoting with its Google Nest division, and Amazon is successfully doing with Ring (one of the busiest booths at CEDIA Expo 2019).

Control4 at CEDIA 2019. Borrowing a sentence from Legrand, CEDIA Expo is increasingly about smart home, networking, and infrastructure solutions designed to help integrators create amazing AV experiences for their clients.

A big difference in the residential space is that a large part of the business is also directly related to entertainment technologies and there is a much stronger emotional connection between brands, products, consumers, and end users.  That is where audio technology companies need to strengthen their market position. Audio technology companies in the CEDIA space typically sell whole home audio and entertainment products such as home theater. And it's not about supplying only the most "installer-friendly" solutions, but actually reinforcing the emotional connection with the end user.

That is the largest challenge for the industry. Many audio companies exhibiting at the CEDIA show are great at designing in-wall, ceiling speakers and black box rack solutions that the custom installation professionals really appreciate, but their own clients struggle to recognize the value. On the other hand, there's already a new generation of home owners, who actually have a strongest emotional connection with Apple, Amazon or even Sonos or Bose, and actually value acquiring a new smart speaker or soundbar from those companies, more than they do with any other "home" technologies.

That is increasingly a challenge for the home theater segment, which always was and remains one of the strongest application segments for CEDIA. After attending the many excellent home theater demonstrations at this year's CEDIA Expo, I couldn't help thinking that the current consumer is increasingly distant from the products and technologies that make the whole experience. That is in part what explains the strong sales in large screen TVs and soundbars, and the dramatic contraction in sales of integrated AVR amplifiers/processors, which remain essential to the home theater immersive experience.

One thing I couldn't help noticing at this year's show is how the professionals themselves in the residential industry have an emotional connection with the systems exhibited at CEDIA, and are all enthusiastic users of the same systems they are selling. That explains the long lines of people (professionals), eager to attend the DTS, Klipsch, PMC, Theory Audio , or any other great home theater or high-performance audio demonstrations at this year's show. And the fact that I overheard installers repeating the statement that when they are able to provide that same level of excitement to their clients, in their own demonstrations, they are easily able to convince them to buy the products and systems they sell - service included.

The problem is CEDIA is a show for professionals, not end users, and the consumer is currently much more emotionally motivated to invest in a new smartphone or streaming service, than they are about the products and technologies this segment is selling. And consumers have very few opportunities to experience the benefits and advantages of integrated, custom install solutions.

Sonos' appeal to the residential integration sector was visible at CEDIA 2019.

That is exactly what companies like Sonos - with its extensive strategy of crossing over all channels, including the residential integration - are trying to achieve: increasing their chances to engage directly with consumers. Sonos' latest partnership with IKEA is the greatest example of a brilliant strategy to get closer to homeowners, while its latest products - the portable Sonos Move, the updated Sonos One SL speaker, and the Sonos Port interface - were standouts at the 2019 CEDIA Expo. Effectively, as Sonos explains, the Sonos Port was "designed with the professional installer community in mind," helping to expand the Sonos smart sound system to traditional stereos and receivers, and make it easy for consumers to add streaming capabilities, while still connecting existing sources (e.g., vinyl, CDs, and stored audio files) to Sonos speakers in multiroom installations around the home.

At the same time, Sonos announced a new set of surprising agreements with other manufacturers, working in partnership with Legrand, SnapAV, and Onkyo/Sound United. The agreement with SnapAV is actually a distribution deal, where SnapAV (the new owner of Control4
) will sell and integrate the entire range of Sonos' wireless music systems, in a strategy that directly targets the professional custom integrator.

But maybe even more symbolic is the agreement with Onkyo, the Japanese company that recently sold its Home AV business, which includes products by Pioneer, to Sound United, joining a now extensive portfolio of brands such as Denon, Polk Audio, Marantz, Definitive Technology, HEOS, Classé, and Boston Acoustics.
During CEDIA 2019, Onkyo USA confirmed that it will also start selling Sonos' wireless music systems nationwide. The distribution deal includes reselling the Sonos by Sonance architectural speaker line, including promoting those solutions on the Pioneer, Elite, and Integra websites.

The emotional connection with products remains strong at CEDIA. But audio speakers designed for the custom channel are struggling, even if providing increasingly high-fidelity performance and designer-friendly architectural profiles. Increasing price competition and a lack of an emotional connection with the end-user are the culprits.

On the technology side, there were also many interesting trends at CEDIA 2019. First, as I noted in a dedicated post on the audioXpress website, following the domination in the commercial sector and professional audio, now Audinate's Dante AoIP is also seeing rapid adoption by manufacturers of residential audio equipment. With Dante now evolving to an AV-over-IP solution, the residential industry is seriously looking at the technology to replace many proprietary solutions. And networking is increasingly a key differentiator in connected home solutions, opening new opportunities to integrators.

A notable paradox, given that Crestron has for the past years been promoting the message at InfoComm that "we can do everything over 1 Gigabit Ethernet," including 4K UHD video distribution for commercial installation, is the fact that the residential sector seems to be quickly embracing broader bandwidth solutions, including Wi-Fi 6, because wireless networks are now faster than Gigabit Ethernet, providing data rates up to 10 Gbps. Very curious.

And I'll leave the analysis of voice trends in home automation control for another article...

Examining the miniDSP EARS Headphone Test Fixture
By  Stuart Yaniger
 
In the March 2019 edition of audioXpress focusing on Test and Measurement, Stuart Yaniger explored the new Earphone Audio Response System or EARS, which miniDSP introduced as an affordable test jig for headphone measurements. Basically, this is a plug & play USB audio streaming device, featuring dual low noise calibrated mics with interchangeable silicon ears. But is it really the answer to bring "headphone measurements to the masses," as the manufacturer intended? Yaniger looks at what can be done with this apparatus, what the trade-offs are, and shares what he learned while attempting some actual measurements.

Voice  Coil Spotlight
Loudspeakers for Vented Enclosures: A Backward Approach for Speaker Selection (LoVE BASS)
By Francisco Castells and José Manuel Requena
(Universitat Politècnica de Valencia, Valencia, Spain)
 
In this article for Voice Coil, the two authors explore the problem of designing vented enclosures, describing a backward concept they call LoVE BASS, which they found to save a substantial amount of engineering hours during the process of speaker box design. As opposed to taking a given driver and designing an enclosure, the authors define the system's target performance in terms of physical volume, lower cut-off frequency, ripple, and maximum achievable SPL, after which they look for candidate drivers that allow for such a design. This article was originally published in Voice Coil, July 2019 .   Check it out here!
