Sonos CEO John MacFarlane during a first press demo of the Playbar earlier this month in the company’s development facility in Santa Barbara.

I had the chance to experience the Soundbar firsthand at a day-long press event at the company’s headquarters in Santa Barbara, California, earlier this month. I also got to see the company’s development labs and talk to its executives.

And when I left Santa Barbara 24 hours later, I realized that the story of Sonos was at its core not just about speakers and soundbars — but about the way entertainment has changed, and is changing in years to come.

The speakers for the Spotifys of this world

Here’s the thing you need to know about Sonos: it’s not a HiFi company. Not in the traditional sense, anyway. Instead, it’s a technology company that has been building hardware for the future of music. The speakers for the Spotifys of this world, if you will. “When we founded the company, we had the fundamental belief that in five years, everyone is going to stream (their music),” said co-founder Tom Cullen.

It didn’t quite happen that fast, and Sonos’ part in the home entertainment revolution almost didn’t happen at all: CEO and co-founder John MacFarlane, who had sold his previous company Software.com for close to $6.9 billion in stock in 2000, had his eyes set on revolutionizing connectivity in airplanes when he was ready to start a new company in 2002.

Check out my interview with Sonos CEO John MacFarlane, or continue reading below:

Software.com co-funder Cullen thought that was a terrible idea, and MacFarlane went back to the drawing board. When they met again some weeks later, MacFarlane was working on ways to network home stereo components with Linux. (For more on the history of the company, check out Stacey Higginbotham’s GigaOM story: How to build a consumer platform: lessons from Sonos. )

Since then, Sonos has been slowly working away on the vision of a wireless audio fabric in your home, selling a few million units to date. The company doesn’t give out exact numbers, but I’ve been told by a spokesperson that Sonos is now “streaming music in over 2 million rooms globally.” And now, it wants to add TV to the mix.

The Soundbar: Great when paired up with the rest of the family

Some five years ago, Cullen proposed that Sonos should build a soundbar. And for the past two years, a team of 100 has been working exclusively on the product. “For us, this is a breakthrough day,” said Cullen when he and his team unveiled the Playbar to journalists.

Hilmar Lehnert, Engineering Project Manager at Sonos, shows off the internal components of the playbar.

So how does this breakthrough look and what does it sound like? The Playbar is at first look a typical soundbar for your TV, combining nine individually amplified speakers for a room-filling home theater experience. It connects to your TV via optical audio, and comes without any additional remote control. Users can instead control the volume of the bar with their TV remote.

Or they just take out their mobile device and fire up the Sonos Android or iOS app, which also offers access to streaming music from Spotify, Pandora and Rhapsody, as well as music stored on a local PC.

As far as the sound goes, I’m the first one to admit that I’m probably the wrong person to judge. I subscribe to the good enough philosophy of enjoying entertainment. I’m the guy that’s happy with $50 headphones. Still, after getting an extended listening demo of the Playbar, I have to say that it is pretty good, but not mind-blowingly awesome.

That changes once you add other Sonos components into the mix, which is one of the key strengths of this product. The Playbar can easily be paired with the company’s wireless sub. And once you add two wireless Sonos Play3 speakers, you end up with great surround sound.

A company without specs in a world where good is good enough

Here’s another thing worth noting about Sonos: The company doesn’t do specs. You’ll be hard-pressed to find anything about the wattage of the Soundbar, or for that matter any of Sonos’ other speakers, on its website. Instead, it emphasizes an Apple-like “just works” approach, and doesn’t bother you with the data points and frequency curves that are so important to hardcore HiFi equipment geeks and home theater enthusiasts.

Sonos favors an Apple-like design approach over complicated specs and gatgetry.

The problem with that approach is that is quickly becoming mainstream in the home entertainment space. The whole idea of a soundbar is to not spend thousands on the perfect home theater equipment, but have something that works better than the flimsy speakers of your TV — and many much-more- affordable soundbars do that just fine. Add Bluetooth to the mix, and that cheap speaker may even be able to stream Spotify.

And the competition isn’t sleeping: Sonos may have figured out how to make wireless audio in the house work, but others are quickly catching up. Apple’s got AirPlay. Google showed how interested it is in the home audio space when it released its ill-fated Nexus Q last year. And Qualcomm recently teamed up with ODM speaker manufacturer Tymphany to add its DLNA-powered Skifta audio module to soundbars and other stereo components.

Another challenge is that the future of home entertainment may depend as much on the home as on the entertainment. As houses get smarter and devices become networked, there is a real need to tie all of this together, have your fridge message your TV and your personal assistant talk to you through your speakers. MacFarlane told me that the company doesn’t plan to venture into the smart home space. Instead, it wants to provide APIs to get other services to talk to Sonos devices. But will that be enough?

Rooting for the good guys

Sonos doesn’t use off-the-shelf components – but is too modest to talk specs.

What Sonos has going for it is its attention to detail combined with its desire to make things simple. That has led to a company heavily invested in engineering and design. A company that develops almost everything in-house. And we are not just talking about the audio components. “We design all our antennas,” Cullen said.

Sonos is a company that’s incredibly proud of its technical achievements but that’s also too modest to talk tech specs. A company that has developers on both coasts as well as in Europe to get the best people for the job. A company that even gives its support staff stock options. It’s the good guys. You want to root for them, but you’re not sure if they’re really going to come out on top.

Home theater

If you want to bring your Apple products into the home theater, you might want to start with the new Epson Megaplex projectors with an integrated iPhone/iPad dock. The Epson MG-850HD provides 720p video (and integrated speakers) from a 3LCD system with 2800 lumens: plenty bright to use for business presentations by day and movie screenings by night. You can quickly set up a screening for the kids by playing a movie from the iPad or running an app that allows video output over the 30-pin dock connector. Priced at $800, the Epson Megaplex is perfect for setting up an outdoor movie night for the kids and their friends.

Crestron is well-known for its high-end home theater and automation equipment, and it’s a first-time exhibitor at Macworld, showing off the Crestron Mobile Pro control app for iOS. The app replaces proprietary touchscreen controllers, which can cost thousands of dollars, with a software solution that works just as well on your existing iPad.

Audiophiles

On the music side, we also have consumer and audiophile offerings. SRS Labs is showing off its iWOW 3D accessory to enhance the audio for headphones or the car stereo, as well as a music player app that incorporates the company’s sound processing technology along with some high-end features like 10-band EQ and tempo adjustment.

Audioengine is showing off its DACs (digital to audio converters) for improved sound quality to powered speakers. The D1 ($169) or the wireless D2 ($599/set) DACs work great with the Audioengine 5+ bookshelf speakers the company had on display. At the high end, Peachtree Audio is also showing off its converter offerings, ranging from the small DAC•iT ($449) to the world-class Grand Integrated ($4295). All these DACs are capable of playing high-resolution 24/96 audio files, far better than what you can get from CD.

Speakers and headphones

Monster has its Clarity HD bookshelf speakers ($749) on display. You can also check out the Audioengine 5+ speakers mentioned above. Bang & Olufsen is at the show with its BeoSound 8 iPhone dock boombox and the portable BeoLit 12 AirPlay system.

Accessories

MicW has a nice calibrated cardoid mic for the iPhone and iPad you can use with a sound pressure level meter iOS app to EQ your room or concert hall. Studio Six Digital is showing AudioTools, its acoustical test and measurement app.

Blinq is demonstrating a universal remote app (and IR emitter) to control your whole setup and connect to a social program guide. Another remote is the VooMote Zapper, which combines an app with an IR blaster built into a case, coming soon to an Apple Store near you.

That’s my list of highlights for sound, picture and video fans keen on what’s interesting at Macworld | iWorld this year. Let us know if you spotted anything equally interesting.
