The idea of mating a dynamic woofer to a ribbon midrange/tweeter is appealing on paper. Such a "hybrid" loudspeaker would have the many advantages of a dipole ribbon transducer, yet be more practical and affordable than full-range ribbon designs. Among the ribbon's great strengths is its narrow vertical dispersion (reducing the ceiling and floor reflections), contributing to the ribbon driver's well-deserved reputation for transparency, terrific soundstaging, transient zip, and excellent resolution of detail. By adding a dynamic woofer to a ribbon midrange/tweeter, the system cost can be contained compared to a full-range design.
This is my fourth review of a Revel loudspeaker, and I was even more excited by the arrival of the Ultima Studio2s ($15,999/pair) than I was when their predecessors, the original Ultima Studios ($10,799/pair when first reviewed; $15,000/pair when last listed in "Recommended Components"), were delivered in 2000. (See my review in the December 2000 Stereophile, Vol.23 No.12.) After all, the Studios were my reference speakers for years and, along with the larger Ultima Salons, were statement products that were the product of the talented designer Kevin Voecks and the considerable resources of Harman International, parent of Revel as well as of JBL and Infinity. Over the years, I've also reviewed Revel's Performa F30 (May 2000, Vol.23 No.5) and Concerta F12 (July 2006, Vol.29 No.7), each outstanding at its price point. If, after all these years, Voecks and his team were ready to reconsider their statement products, they should be something special.
Danish Audiophile Loudspeaker Industries (DALI), a relatively large maker of loudspeakers, was founded in 1982 by the peripatetic Peter Lyngdorf, who has worked with or founded Steinway/Lyngdorf, Lyngdorf Audio, TacT, NAD, etc. Audionord International, another company founded by Lyngdorf, owns DALI as well as American subsidiary DALI USA, along with yet another Lyngdorf creation: the 60 Hi-Fi Klubben stores, said to be the world's largest chain of high-end audio retail shops. Whew! The guy keeps busy.
These speakers inadvertently managed to put me in a good mood even before I listened to them, because of a dumb little gaffe committed by Thiel's packing department. Each speaker came with an Owner's Information sheet, which is nice. Each sheet included Unpacking (and Repacking) Instructions, which is nicer. But each sheet came packed inside the carton, underneath the speaker, where it was not accessible until after the speaker was dumped out of the box, which is pretty silly!
The Dalhquist DQ-10 loudspeaker has not as yet been formally submitted for review. (The designer tells us he is still working on the low end.) We auditioned a pair at the one local dealer we could find who had the DQ-10s on demo, and were immensely impressed. Obviously, Jon Dahlquist is on to something that other speaker designers have been overlooking, for, despite the multiplicity of driver speakers in the system, the DQ-10 sounds like one big speaker. There is no awareness of crossovers or separate drivers (except at the low end, about which more subsequently), and the overall sound has a degree of focus and coherence that is surpassed only by the Quad full-range electrostatic, which don't go as low at the bottom or as far out at the top.
"DAL firmly believes that a full set of credible measurements, made by qualified engineering staff using state-of-the-art equipment and facilities, can reliably predict the potential of a loudspeaker to accurately reproduce the complex sounds of music."—Dunlavy Audio Labs
After reviewing a long series of minimonitors, I am now working on what may well be an equally varied selection of large floorstanding loudspeakers. This trend began with my review of the Sonus Faber Cremona Elipsa in the December 2007 issue, and continues this month with the Series 2 version of the KEF Reference 207, until recently the flagship model from this English manufacturer (footnote 1). I reviewed the original Reference 207 in February 2003, and was very impressed by what I heard.
When it comes to loudspeaker drivers, Dynaudio has earned an enviable reputation for quality and reliability. To use an automotive analogy, they are the Mercedes Benz of the driver universe. If you're a speaker builder, the odds are that you have already experimented with these drivers. And even if you're not a speaker builder, it's quite possible that your speakers use Dynaudio drivers. After all, some of the finest speaker systems in the world do. A case in point is the Duntech Sovereign, which single-handedly embodies almost the entire Dynaudio catalog.
The Ohm Walsh 5 displaces the Ohm F at the top of the Ohm line, and the current Walsh 5 production run represents a "limited edition" of 500 pairs worldwide. There's even a certificate of authenticity—hand-signed by Ohm Acoustics President John Strohbeen—packed with the speakers that makes it all official. I think that this is more than a clever marketing gesture and clearly demonstrates Ohm Acoustics' pride in their new flagship loudspeaker.
It is the audio writer's nightmare that the combination of the large number of exhibitors at a Consumer Electronics Show and the very limited amount of time the Show's doors are open will lead him to miss the event's biggest story. I came close to living that nightmare last January, at the 2007 CES, when I realized that I had missed an entire floor of Las Vegas's Venetian Hotel. And it was, of course, the floor where, among other high-profile high-end companies, Sumiko was debuting the Cremona Elipsa from Italian speaker manufacturer Sonus Faber.
Richard Vandersteen was in good form at the 20th-anniversary seminar held by retailer Advanced Audio on November 11, 2006. When asked about his priorities in loudspeaker design, he sat erect in the seat next to me and thundered, "I will not [slams table with open hand] spend one red cent on cosmetics that I could have put into improving the sound of a loudspeaker!"
I only found out after beginning my auditioning of Mirage's M-1si loudspeakers that the film 2001, A Space Odyssey was, at practically the same instant, undergoing a brief theatrical revival in major cities around the US. I might have known. Perhaps it was the persistent Strauss melodies that rattled around in my head as I set them up. Perhaps it was the two 5'-tall monoliths that subsequently stared at me as I sat in my listening chair. For whatever reason, the M-1sis were an imposing sight, and the association with out-of-this-world events was not a difficult one to make.
To many audiophiles, the name Boston Acoustics is synonymous with mass-market budget loudspeakers. Although many of its products have offered good value for the money, Boston Acoustics has never been known for driving the envelope of high-priced loudspeaker design (footnote 1). The company has been content to churn out well-designed, affordable boxes and let others attempt state-of-the-art loudspeakers. Until now.
