Big House, Cheap Audio

The Eos multiroom sound system isn't slick, but it won't stress your budget

For several years now I’ve had Sonos envy. Several of my friends own these high-end multiroom audio systems; when dinner-party conversation lags, we pass the handheld controller around the table to play memorable songs and reminisce. (Okay, a bit strange, but this is Silicon Valley.) Unfortunately, Sonos systems are complicated and costly: Just the starter pack, with the wireless controller and boxes to hook up two rooms, sets you back US $1000, and that’s without speakers.

So when I heard that a company named IntelliTouch, in San Diego, would soon offer a low-cost multiroom audio system called Eos, I was excited. ”Low” is a relative term, of course. The Eos Wireless starter pack—a base station, a remote speaker unit, an audio cable for hooking up other components, and a remote—lists for $250 but sells for as low as $150. (The controller is built into the speaker.) Additional speakers are about $130 each.

Televisions and computer monitors with QD-OLED displays are now on store shelves. The image quality is—as expected—impressive, with amazing black levels, wide viewing angles, a broad color gamut, and high brightness. The products include:

All these products use display panels manufactured by Samsung but have their own unique display assembly, operating system, and electronics.

I took apart a 55-inch Samsung S95B to learn just how these new displays are put together (destroying it in the process). I found an extremely thin OLED backplane that generates blue light with an equally thin QD color-converting structure that completes the optical stack. I used a UV light source, a microscope, and a spectrometer to learn a lot about how these displays work.
