Both Linaeum speakers have similar average B-weighted sensitivities at around 86dB/2.83V/m, While the Model 10's impedance (fig.1) doesn't drop below 6 ohms over most of the audio band, the Linaeum Center Speaker has an impedance of 4 ohms or below through the music and vocal "power region" in the lower midrange (fig.2), meaning that a receiver or amplifier rated into 4 ohm loads should be used.

Which loudspeakers do audio professionals listen to? And why should we care? After all, it's not as if recording engineers are the kind of refined, sensitive, music-loving types who read Stereophile. As much as they may love music, many audio pros appear only to view the original sounds of musical instruments as raw materials to be creatively reshaped and manipulated. (Okay, there are exceptions. But recordists who care about the sounds of real instruments usually record them in real acoustic spaces rather than in studios, and use as little signal processing as they can get away with.)

I installed a pair of the 1031As on 28" stands in my 16' by 20' main audio/video room, with the speakers and listening seat at the corners of an equilateral triangle. The rectangular cabinets were oriented vertically, placed symmetrically in relation to the room's side walls, and 4' from the back wall. The listener-to-loudspeaker distance was about 7', and the speakers were aimed straight ahead, as they'd been when I first heard them at Colorado Sound (and as they would be in most other studios). The surround channels went on 6' stands 7' behind me, near but not close to the room corners,…

Because it's a powered design, measurements of the Genelec Studio Monitor 1031A's impedance and sensitivity are irrelevant. The Genelec's cabinet was quite lively in the bass-reflex tuning region, with a single resonant mode also evident in the midrange (fig.1). The latter might add a hint of "slowness" to the satellite's bass quality, though predicting the subjective effect of the midrange mode is harder; it might be high enough in frequency and low enough in level to be more benign than expected.

Folks, if you're traveling to Chicago to attend the 2019 Audio Expo North America (AXPONA), you've got to have the AXPONA app. It's free, and you can download it from a link on the AXPONA website. Last year, American audio shows felled more than ten million 100'-tall trees—just for their ink-on-paper floor plans. They had to reopen two nuclear power plants just to keep the elevators running in Las Vegas. The Chicago River backed up like a toilet—clogged by discarded show guides. This year, all you need is a smart phone, the AXPONA app—and the stamina to visit almost two hundred rooms filled…
In the middle of AXPONA's annual pre-show industry reception, held Thursday evening in the huge Schaumburg Ballroom of the Schaumburg Hotel & Convention Center, Paul Miller (on the right in the photo above), Director of AVTech Media/AVTech Media Americas—which publishes Stereophile, AudioStream, InnerFidelity, AnalogPlanet, Sound & Vision, and the UK's Hi-Fi News & Record Review (amongst other properties)—unexpectedly took to the stage. With the assistance of Show Organizer Liz Miller, Paul honored Stereophile's former Editor-in-Chief, John Atkinson (now Technical Editor). Yours…
The show was scheduled to open at 10am today (April 12), but at 9:55am there was already a line of people at the registration desk. AXPONA looks on track to replace CES as the premier audio show in North America.
One of my first stops this morning—the first morning of AXPONA 2019—was the Shunyata room in the Renaissance Schaumburg Hotel. Shunyata, as you're probably aware, has long been one of the more scientific-minded of the companies focused on quality power for home audio systems.
I learned today that Shunyata has an expanding presence in the medical industry; It's actually a sister company, Clear Image Scientific. One graph displayed in the Shunyata room showed a huge reduction in noise in what appeared to be an EKG; see the image below. (Apologies for the poor image quality.)
