Signet SL280 loudspeaker Measurements

Sidebar 2: Measurements

The impedance magnitude and phase angle for the Signet SL280 are shown in fig.1. The double peaks in the magnitude plot below 100Hz are typical of a reflex tuned cabinet. Note that the minimum impedance of the system is just below 7 ohms (at about 150Hz), indicating that no competent, appropriately powered amplifier (into 4–8 ohm loads) should have any difficulty in driving the Signets.

Fig.2 shows the impulse response. The ringing in the tail of…

For Record Store Day: Dave Douglas, <I>Dark Territory</I>

First things first. Yes, Dave Douglas named his new album, Dark Territory, after my new book of the same title. This may seem odd: my book is about the history of cyber war; Douglas' album is a deep-dive exploration of improvisation, composition, and technology in the risky corners of jazz and electronica. But in an email sent out by his self-owned label, Greenleaf Music, he explains that both works are about "similarly mysterious murky waters of underground activity" and that he found my title fitting because, like the characters in my book, he and his band are "playing through a similar…

Hitting Mailboxes and Newsstands Today: the May Issue

The least-expensive Wilson speaker and the most-expensive Vandersteen speaker go head-to head in the May issue, accompanied by reviews of PS Audio's affordable DSD DAC, Schiit's high-value Ragnarok integrated amplifier, Vandersteen's unique monoblock amplifier, and Luxman's high-performance EQ-500 phono preamplifier.

With Michael Fremer on vinyl playback, Art Dudley on a rebuilt Naim amp, Kal Rubinson on surround sound, and Steve Guttenberg polling speaker designers on how close they are to achieving "accuracy," our 140-page May issue has something for everyone.

AXPONA's Solid Start

Even before 10am had rolled around on opening day, eager audiophiles were obtaining badges in the lobby of the Westin O'Hare. It looked like a very promising start.

Steve Davis, who founded AXPONA in Jacksonville, FL eight years ago, was just finishing up Friday morning's press briefing while people were already lining up in the lobby. Among other things, he led us on a tour of the new Manufacturer's Showcase, in which 26 manufacturers and distributors set up passive displays of premiering and recently released products. Even in this, its first year, the showcase ran short of…

AXPONA: Lower Level Vistas

Once Pro Musica Chicago discovered that one of the electrical outlets in their room was severely handicapped, as it were, and switched to another, the VTL TL5.5 preamp with phono stage ($10,500) and VTL S200 power amp ($12,500) delivered eminently neutral sound. On a classic recording of Falla's Three Cornered Hat, the presentation had all the midrange weight, warmth, and fullness I've come to expect from VTL gear. The sound was wonderful.

Storeowner Ken Christiansen, whose True Stereo recordings for NAIM are highly prized, used Chord Co. balanced interconnects ($500) and Super Lumina…

AXPONA: Herb's First Day

At every audio show I visit, there's always more live action, more vivo, more hormones, and surely less gray hair in those large rooms where people exhibit headphones, sell new and pre-owned LPs and CDs, and put on static displays of products that are just coming on the market. AXPONA was no exception, with their lobby-level Ear Gear Expo, Manufacturer's Showcase—which was stocked with excellent food and beverages for the show's opening party—and Marketplace.

Because the energy is so strong, I always feel drawn to these rooms, and once there, I lose time, spend money, and feel young again…

AXPONA: Herb's Friday Postlude

I became angry when I first heard Elac America's new UB5 loudspeaker. Why? Because, at the time, I was working on my review of another Andrew Jones's design—the Elac B6 ($279.99/pair)—and the $499.99/pair UB5 sounded so *%##@ good, I was thinkingwell, damn! For $200 more I could be experiencing the Jones-designed coincident mid-tweet driver with its pinpoint imaging and slamming bass. Yes: I said slamming bass.

I always laugh at Andrew Jones's demonstrations, because every time he plays some bass-slamming blockbuster, the curtains behind the speakers start flapping in the breeze from…

AXPONA: Jason's Friday Finish

I scored big this year, because my floors included High Water Sound's room. As usual, Jeffrey Catalano was a breath of fresh air, playing LPs of music not encountered in other rooms. First came a movement from Shostakovich's String Quartet 9 (performed by the Fitzwilliam Quartet, dressed in echt '70s slim-cut suits), which sounded gorgeous. Next, Lou Reed and John Cale's Songs for Drella, which showcased the system's strong but balanced midrange. Finally, The Cairo Gang's "At the Show," recorded in 2007 in Chicago, on which the guitar's sound was to die for.

It's not just Jeffrey's…
