Adoption of DSP-based speaker-and-room correction in home theater—a parallel universe to audiophilia—is almost universal. It's easy to understand why. Home theater matured in the digital age. Its fans were expected to install several loudspeakers in a full-range setup that included at least one speaker—the subwoofer(s)—that functioned exclusively in the problematic bass region. Setup issues were intimidating.

Dutch & Dutch 8c active loudspeaker system

Stand Loudspeaker Reviews

Kalman Rubinson | Jul 25, 2019 | 54 comments

At first glance, this active, DSP-controlled loudspeaker system, with dynamic drivers firing to front and rear, may seem an alien invader from the world of recording and mastering monitors made by such brands as Neumann and Genelec. I wouldn't dispute that perception, but I offer another perspective: The engineering that has gone into the Dutch & Dutch 8c ($12,500/pair) is an all-out attempt to meet the goals that all designers of high-end speakers hope to attain: wide, smooth frequency response; sufficient and linear dynamic performance; crossover management; a cabinet free of audible resonances and edge diffraction; control of the dispersion of sound energy throughout the audioband.

Dynaudio Confidence 30 loudspeaker

Floor Loudspeaker Reviews

Over a lifetime of audio shows, I've consistently enjoyed Dynaudio speaker demonstrations. Each time, I've told Dynaudio North America's Michael Manousselis that I'd love to review the speaker on display that year. But I never followed through. So, when Jim Austin suggested I review a Dynaudio speaker "because they haven't gotten much press," it resonated with my deep-seated guilt. A little research revealed that the last Dynaudio speaker Stereophile reviewed was the 40 Special in November 2018. The last floorstander was the Dynaudio Sapphire in 2009!

Dynaudio Drops XEO Prices

CES 2014

Kalman Rubinson | Jan 16, 2014 | 0 comments

I was getting bored with my own opening question asking exhibitors do you have anything that's new for under $2000. For two days, I was getting either a gleeful "Yes!" or a slow "No but . . ." Mike Manousselis, Director of Marketing for Dynaudio USA, surprised me with a new answer: "Well, we have something that is not new but it's price is new and it is now under $2000."

Dynaudio Gets High-End Sound from the iPod

CES 2007

Kalman Rubinson | Jan 11, 2007 | 1 comments

At the Las Vegas Convention Center, Dynaudio was showing—and playing—its new self-powered MC15 mini speakers. In three setups, they were connected to a laptop, a gaming console and an iPod dock, each setup clearly indicating that its high quality sound was an improvement over the usual powered computer speakers. Sporting a 6" woofer, an Esotec soft-dome tweeter (with 1st-order crossover at 1.5kHz), and a pair of 50W amps, this $1299/pair package, including elegant table mount, would be even more suitable as the basis of a deskop system with a good disc player.

Dynaudio Goes On-Wall

CEDIA 2006

Kalman Rubinson | Sep 17, 2006 | 1 comments

While on-wall/in-wall systems were ubiquitous at CEDIA, the in-room speakers stood out for their imaging and sound quality. Even the tiny Dynaudio 2.1 system consisting of a pair of Contour SR speakers ($2200/pair) coupled with the Sub 250 ($1k) made sounds that many bigger installations would envy. Add another pair and a Contour SC ($1900) to fill out a 5.1 system that can do music as well as movies.

I have been a proponent of methodical modeling and room analysis as aids in setting up audio systems and rooms. They work hand in hand: Modeling predicts a feasible room arrangement, and analysis, along with careful listening, determines how close the outcome is to that predicted. Of course, there should always be another round of modeling to see if the current setup can be improved with more work. The spiral continues, toward, one hopes, perfection.

Empty glasses!

CEDIA 2006

Kalman Rubinson | Sep 15, 2006 | 2 comments

Late in the day at the Show, most glasses were filled or in the process of being emptied. This stack on the BG stand, however, was empty. It had been erected to show that Radia's new 210i Active Subwoofer is almost totally vibration-free in operation. At the time I took this picture, this sub, with its opposed 10" Kevlar drivers and 500w BASH amp was pumping out gobs of bass, cleanly and tightly. I could detect no vibrations at all with my hand. What's the point? Well, you can put something on top of them (vase, planter, cigar humidor!) without exciting spurious vibrations. Heck, you could even put this $1500 sub in a cabinet, if that suits your needs.

ESP Loudspeakers Returns

News

Kalman Rubinson | Nov 17, 2003 | 0 comments

Back in the 1990s, I lusted mightily for the large ESP speakers with their tall, slim shapes and their angled driver panels. A large-room demo of the Concert Grands with Sonic Frontiers electronics still reverberates in my memory. Unfortunately, just as I evolved to the point where I could consider buying a pair of Concert Grands, the company folded its tents. Recently, I heard a rumor that ESP might be returning, and an email exchange with founder and designer Sean McCaughan has confirmed the good news.

Estelon AURA loudspeaker

Floor Loudspeaker Reviews

Kalman Rubinson | Nov 24, 2023 | 6 comments

I've been watching Estelon since they came on the market in the US. Their striking appearance grabs the eye, but, preoccupied with other brands and reviews, I was able to deny them serious attention until now.

I had my reasons—especially price. The prices of those earlier Estelons were a poor fit for my budget. I was also troubled by the fact that, despite rhetoric about driver and component choice, advanced cabinet materials and construction, and fastidious engineering, Estelon has been stingy with details and specifications—not a complete disqualifier but rather a missed opportunity to appeal to objectivist proclivities.

What changed my mind? First, while Estelon is deservedly known for the elegance of its designs, the AURA is, to me, the cleanest design the company has yet achieved . . . Second, at $19,900/pair, the AURA is much less expensive than the earlier models, including the Forza reviewed by Michael Fremer and the XB Diamond Mk.2 reviewed by Jim Austin.
