“The first point to make is that there are two distinct types of coloration, additive and subtractive. A little like odd and even-order distortion, subtractive coloration is relatively benign, whereas even small amounts of additive coloration can (and often do) wreak havoc. That’s because of the different ways in which they impact on the sense of the musical signal. The notes and different instruments in a recording constitute a three-dimensional pattern, laid out in space, time and amplitude. That pattern is what separates music from noise; it’s what a system is trying to reproduce and what our brain is trying to recognize. Subtractive distortion, as long as it is not too gross or specific, will diminish the scale or scope of that pattern, but leave it essentially intact. Once you start adding things to the pattern, especially because additive distortion is so often frequency-specific, you start to bend the pattern out of shape, so that it no longer makes sense. A bit of stored energy in a cabinet, arriving later than intended and at the wrong frequency? An energy spike in the structure of a poorly designed driver? Excessive bass output at particular frequencies? You can hear how they serve to alter not just the relative weight or amplitude of notes but their timing too — and that’s where things get destructive.”

“It really is impressive just how bold and confident these speakers are when challenged with the music’s savage dynamics and dense instrumentation. The R1s stay composed even when pushed hard and barely harden-up in such circumstances.

Detail levels are as high as the price point demands, but the Audiovector’s musically cohesive way of assembling all that information really impresses. These are the kind of speakers that allow you to analyse the production of a recording if you want to, but they’d rather you step back and enjoy the musical experience.

When we listen to this Stravinsky piece we’re wrapped up in the musical drama rather than wondering about the mechanics of the recording. That’s just as it should be in our view”

“Play most any recording taken from a concert hall or other large acoustic space and you will “feel” the pressurizing of the room with these speakers. It’s amazing how much ultra-low low bass information there is on many of these recordings and how much that information enhances the illusion of your room being that same concert hall. There is a down side, though. It can get a little disconcerting when you can plainly hear the rumblings of the air ventilation system or the traffic outside the recording site. I hear way too much of this on Chesky’s Johnny Frigo with Bucky and John Pizzarelli and the other recordings made at the RCA Studio “A” site in New York City.

Another down side is that a speaker that goes this low with real authority, will excite room resonances and standing wave problems much more than speakers that don’t move as much air or that have limited range. I don’t have resonance problems in my “audio bunker,” my room being underground with concrete under the floor and on all four walls, but I do have a standing wave problem at about 34 and 37Hz due to the long straight and diagonal lengths of my room. With the Wilsons, they’re heard as only minor peaks—with the VR-4s, they’re quite a bit more prominent. Not to worry though, the problem is nicely solved with a few of ASC’s 20″ tube traps or some of Tyll Hertsen’s (Mr. Headroom’s) home brew frequency specific cancellation tubes. Let’s face it, you have to pay your dues if you want killer bass with no peaks.”
