What's Smart About Apple's HomePod Speaker

Apple launched its $349 HomePod on February 9, 2018.
People tend to forget how Apple enters a category and sometimes takes it time to find the simplest "dumbest" approach to the exact things people want. And for that, they often enter a market segment, see what people do, and evolve or change directions. There's no shortage of examples of products where Apple entered and moved out without saying a word. That includes a speaker - the famous iPod Hi-Fi.
Another example I always like to remember was the actual iPhone. Apart from all the buzz and the impact that the revolutionary concept caused, the first iPhone was a sort of "limited prototype" of what it could be. Soon to be replaced with the iPhone 3G -  the first actual smartphone with real data connectivity, available almost globally, the iPhone only became closer to its full potential with the iPhone 4, four years after the original release.
And despite all the copies and desperate efforts from all the competitors, the iPhone realized the full potential of the concept and allowed Apple to become the largest and most profitable company on Earth. Of course, it helped that all the companies that initially focused on copying everything about the iPhone quickly diverted those efforts to copying the iPad and...we all know that story. With the original iPad, at the time no one understood what it could really be used for when it was launched. The concept was incredibly appealing, the large touch screen experience seemed to be all that was needed to justify its mere existence, and it didn't really bother me that the connectivity was limited to Wi-Fi or, the most glaring of all lacking features, the absence of a camera.
Remarkably, that same year the iPhone 4 and iOS 4 introduced multitasking functionalities and Apple's new FaceTime video chat service, because the iPhone 4 was also the first iPhone to include a front-facing camera. Of course, the original iPad was quickly replaced with a new model that also had a camera and did allow FaceTime calls. And it sold hundreds of millions.
In that regard, Apple could have revolutionized communications forever and be today's dominant player in Unified Communications, removing the likes of Skype and WebEx to oblivion. Instead, Apple never even bothered to upgrade, promote, or do anything with FaceTime, and today's WhatsApp users don't ever remember what FaceTime is and its intended use. Unfortunately, neither does Microsoft apparently, and Skype continues to be a low priority for Redmond's plans. So, yes, Apple doesn't always get it right the first time around.
With the HomePod, it is a similar story. Much in the same way as the first iPhone was limited and didn't actually support the absolutely needed broadband connectivity, now the HomePod is a great speaker that sounds better than anything in its class, but is being received with criticism because of its limitations. And yet, the HomePod actually delivers on introducing the latest technology that defines a "smart-speaker" such as using the latest sensors for spatial awareness (tuning itself to optimize reproduction) and far-field voice detection.
Unfortunately, like the first iPhone, some of its essential features are not yet implemented, such as stereo pairing and AirPlay 2 for multi-room connectivity. More glaring, music integration is limited to Apple Music, and Siri's functionality as a VPA and, even harder to understand, HomeKit integration - potentially the thing that most justifies buying one - is still basic.
Is there a sign that Siri is limited compared to Amazon Alexa or Google's Assistant? Absolutely not, as many reviewers already noted, when Siri works in far-field mode on the HomePod, it can truly shine in terms of voice recognition - but unfortunately, it is not yet connected to the world of services that a Google search engine can provide, and is not able to be Alexa with its "box of tricks" provided by third-party skills and voice-commands.
In general, HomePod reviews all acknowledge the stunning design, the quality of construction, its robustness, the performance, and the sound quality, unlike any other in the "smart speaker" category. In general, HomePod's construction is a wonder - the fabric mesh, the drivers, and the microphone array. Anyone with time for that, can check some of the teardown videos here.

The HomePod is able to fill any room with sound wherever it is placed, and performs much better than much larger speakers such as the Google Home Max, or any Alexa-enabled or Google Assistant available speaker - with much less distortion when pushed to its loudest. In that regard, Apple's speaker designers did their job. Also, the microphone array and the ability to detect the wake-up works "Hey Siri" and understand voice commands while the music is playing seems to be superior to all rival systems.
On the other hand, it's impossible not to note that since it can only be used with Apple Music - for now - its appeal compared with any other similar device is severely restricted. And voice commands for music control are still not convincing. Good luck telling Siri to play that obscure album from your favorite artists, or trying to say the name of a song that's clear basic English words. It's not that HomePod is available only in three English-speaking countries and that voice recognition in general only works well enough in English. The problem is also that it only works with artists, albums, and songs with English metadata. Do you like French music? Want to request "Libiamo Ne'Lieti Calici" from La Traviata by Verdi? You're out of luck!
But like any other Apple device, it works beautifully with all other Apple devices and Airplay sources, and the entire process of pairing and controlling it from an iPhone is pure magic. So, if users ignore voice commands and simply control iTunes or another music app, that problem becomes irrelevant - and probably that's what will happen with the large majority of HomePods sold.
Apple knows that its Siri engine is actually built on artificial intelligence and natural language engines, but it will be a challenge for users already familiar with voice engines that work with keywords and voice commands to understand contextual sequences and multi-step commands. And comparing Apples for Apples (meaning standard voice commands with standard voice commands) Siri works pretty well. If in doubt, just check this video.
Will Siri evolve and learn? Well, the device certainly needs to be updated quickly, offer AirPlay 2 multiroom and stereo pairing, and work with other Apple devices such as Apple TV and - grow in terms of third-party services supported. So, in reality, this is like having an earlier iPhone with limited data services and no apps...
So, as all honest reviewers have started to find out, the HomePod does best what is supposed to do well - playing music! Some of the reviews, as usual, are simply hilarious with comments like "this actually sounds surprisingly great!" coming from people who have lived with Amazon Echos and Google Homes for the past months!

On a more serious tone, our friend Brian Hamilton from NTi Audio did some measurements for Fast Company and "surprise, surprise," the HomePod is "legit" and remarkably good, they say! The most relevant of measured performance being its remarkably low distortion.  What else would you expect from Apple's team, and the combination of the most cutting-edge internal calibration for automatic response correction, direct and ambient audio beamforming AND the best-available dynamic processing ever integrated on a speaker On the wireless front, the HomePod is ready to evolve, featuring 802.11ac Wi-Fi with MIMO, Bluetooth 5.0 (with extended range), and Peer-to-Peer direct access from Macs. I like Fast Company's conclusion that "Apple's definition of 'smart' speaker might simply be different than the common understanding," meaning "sound smart."
The HomePod will get better with an upgrade, and the HomePod 2 (or the Plus) will eventually be the one to buy. By that time, everyone will have already understood what exactly you can do with voice commands and, eventually the real race for natural language recognition will seriously start. By then, no one will remember the earlier efforts with voice... Apple knows that voice recognition is its infancy, and like always, will tune its strategy depending on those very things that users will actually use and value.
Here I should trace another - more recent - parallel - with another Apple product. After the AirPods were launched, most of the reactions - mine included - focused on the non-essential. The truth is, Apple's AirPods are currently leading the true wireless stereo segment with a market share of more than 80% and selling increasingly well. Apparently we disregarded the fact that, when something works well people tend to recommend it to others, and the word spreads. To the point that even a bizarre design like the "cigarette butt" AirPods can become an accepted icon. That's what happened.
In my opinion, Apple did the same with the HomePod, and focused on the fundamentals. This is a reference design using all the available tools that for some time have been available to the audio industry, very well put together. So, don't underestimate the impact that this product is going to have in the overall audio industry. This speaker will make other respectful products sound dull in comparison. Audio manufacturers will have to step up their designs to be "sound smart."

True Bass in a Large Space: A Pro DIY Subwoofer Project from 1975 Using Electro-Voice's 30W 30" Woofer!
By Don Keele, Jr
Part of the audioXpress Speaker Focus edition in September 2017, this article by Don Keele, Jr. reminds us of how things have evolved in speaker design, revisiting a subwoofer project that uses an Electro-Voice 30W 30" woofer from 1975! In "True Bass in a Large Space," Keele writes, "Getting true bass in a small place is quite easy and straightforward today, but back in 1975, it was not!" Inspired by Thomas Perazella's DIY article, "True Bass in a Small Space" (audioXpress, February 2017), Keele describes an equivalent solution from 1975 that provides about the same response and acoustic output but using a high-efficiency low-excursion 30" driver mounted in a massive 76 ft3 vented-box driven by a 60 W amplifier, with a total system weight that exceeds 800 lbs!   Read the Full Article Now Available Here
