Vandersteen Model 7 Loudspeaker Preview

One of the “must-hear” systems at CES was Richard Vandersteen’s all-new Model 7 loudspeaker. The buzz surrounded not just the exceptional sound the system produced, but the radical departure that the Model 7 represents for Vandersteen Audio. The $45,000 Model 7 is an advance not just in technology and sound quality, but also marks Vandersteen’s entry into a completely new price category after more than 30 years of producing value-oriented loudspeakers.
 
Walking into the Vandersteen room, I was surprised that the Model 7 is actually smaller than Vandersteen’s Model 5. I was also surprised to see the speaker finished in a bright red, high-gloss paint.
 
The Model 7 is a four-way system employing a 12” powered (400W) push-pull woofer taken straight out of the Model 5. The midrange, mid-bass, and high-frequency drivers, however, are made from a three-layer sandwich of balsa wood flanked by carbon fiber. Even the ScanSpeak Illuminator tweeter uses Vandersteen’s sandwich dome. Vandersteen makes the cones and ships them to ScanSpeak, who builds the drivers. Vandersteen has applied for patents on this cone and dome technology.
 
The enclosure is made from five layers of carbon fiber in a constrained-layer-damping configuration that is then bonded to a carbon-fiber skeletal structure. The faceted shape makes it difficult to apply wood veneers, but Vandersteen intends to offer veneered versions in the future at a price premium.   
 
The crossovers are fully balanced (each leg of the balanced signal is filtered) and the capacitors are battery biased with a small amount of DC. Of course, the crossovers are all first-order to maintain the time and phase coherent nature of all Vandersteen loudspeakers.
 
The Model 7’s sound was extraordinary: coherent, open, uncolored, dynamic, and with a purity of timbre that was striking. But the Model 7 really excelled in resolving very low-level details such as reverb decay and the sense of space around instruments. I’ve heard Stevie Ray Vaughan’s Couldn’t Stand the Weather on many systems over the years, but I’ve never heard the sense of presence to his guitar, the vivid impression of a guitar amplifier in the studio, and of the fine texture of the instrument’s decay that I heard from the Model 7.
 
Incidentally, the rest of the system included the Aesthetix Io and Callisto line and phonostage, Aesthetix Atlas solid-stage amplifiers, and the Clearaudio Statement turntable. There was no digital playback in the room.

Robert,
  Should exhibitors always have digital playback available in their show room along with their vinyl?
Thanks!

I second Robert's assessment of -- and share his excitement about -- the new Vandersteen. One additional attribute I noted is the speaker's astonishing coherence. This was one of Richard Vandersteen's design goals, thus the use of common cone materials top to bottom. The goal was achieved in spades! These speakers are so coherent -- that is, they sound like one driver rather than an array of different-sized drivers -- that they expose how incoherent most dynamic speakers actually are. The sensation of listening to, say, a full-range ribbon rather than a multi-way dynamic was eery. Bravo, Vandersteen!

I mentioned that Vandersteen had no digital playback as a matter of interest, not as a criticism. However, it makes it impossible to play familar music on the system unless you carry around your own LPs (as Jonathan Valin does).

I think the feeling is that CD is not at the fidelity level of LP and you would not here a big difference. You need a good source and until the industry gets a good digital source LP is still the best and he wants to demo the best. I see his point but like most people I listen to cd and a music server on my vandies some day I will have something better but LP are just not practical.
I think the feeling is that CD is not at the fedility

The Model 7 is a four-way arrangement employing a 12” powered (400W) push-pull woofer taken beeline out of the Model 5 ccda dumps. The midrange, mid-bass, and high-frequency drivers, however, are fabricated from a three-layer sandwich of balsa copse belted by carbon fiber. Even the ScanSpeak Illuminator tweeter uses Vandersteen’s sandwich dome. Vandersteen makes the cones and ships them to ScanSpeak 70-455, who builds the drivers. Vandersteen has activated for patents on this cone and arch technology. The asylum is fabricated from 5 layers of carbon cilia in a constrained-layer-damping agreement that is again affirmed to a carbon-fiber ashen structure ccie training. The faceted appearance makes it difficult to administer copse veneers, but Vandersteen intends to action veneered versions in the approaching at a amount premium 70-516.
