Outstanding features of the PureVOX for me are the robustness of the Aluminum cabinet with special dampening characteristics, the quasi-Bi-polar design, high performance drivers, and the tone switch. The cabinet reminds me of super-tight, extremely dense and non-resonant cabinets of far more pricey speakers such as the reviewed Wilson Benesch Curve, and the YG Acoustics line. My ears tell me that one cannot go far wrong with a hefty aluminum cabinet, as the PureVOX was clean and clear in ways that wooden and MDF cabinets in my experience have not been. If the prospective buyer wishes to have a sensation of hearing predominantly the drivers, not the contribution of cabinets, then the PureVOX is a marvelous choice.
There are other good small towers at the price point of the PureVOX, but any of them with a wood or MDF type enclosure will carry that telltale hollow box sound. The PureVOX avoids this, and as such is a step above in terms of pristine presentation. The cabinet can never be taken entirely out of the equation when it comes to adding up the sound of a speaker, but the PureVOX, as with other speakers with highly damped metal cabinet construction, reduces the contribution of the cabinet in a beneficial way such that even though it is a dynamic speaker it strikes the ear as though more is being heard of the drivers themselves, versus the cabinet. This fools the ear into thinking it is hearing a dipole speaker without a cabinet, where the drivers radiate forward and backward unencumbered by an enclosure.
While on the subject of hearing the drivers, I will address the issue of being Bipolar. To be Bipolar is not a good thing for a human, as it leads to a roller coaster life, sometimes pitching to and fro emotionally. However, a Bipolar speaker is a good thing, and for those who cannot sacrifice the space necessary for a larger dipole speaker it becomes a viable alternative. The PureVOX’s 6.9” Kevlar/fiberglass bass driver was refreshing to hear, as I have enjoyed such Kevlar/fiberglass cones in speakers previously. I was sorely tempted to purchase the affordable Wharfedale Opus bookshelf speakers I reviewed, which carried Kevlar bass drivers, simply because they sounded so good! In the PureVOX I was hearing again potent, yet pristine bass from a reasonably sized enclosure.
I have taken a liking to all manner of ribbons, and assess the AMT tweeter in the speaker to match the capabilities of the original 1” AMT in the Legacy Whisper Clarity Edition loudspeaker. This driver also is duplicated on the back, angled baffle of the PureVOX. Whereas two of these ribbons might be overpowering if fired directly at the listener, the ever so slight dilution of the crispness of the ribbon through time adjustment by being fired backward prevents it from sounding too bright or etched.
This combination of drivers would be quite acceptable if employed in a traditional box speaker design. However, the addition of a rear firing set of identical drivers on what appears to be a 45-degree angle changes the ball game hugely, making it a competitive speaker to far more costly floor standers. The rear/upward firing drivers enlarge and deepen the soundstage vastly, making the PureVOX sound more like a 2-meter tall monster, though with not as imposing bass. The angled rear drivers are not a solution without placement issues. These speakers more than non-bipolar speakers must be toed in carefully. The soundstage is so affected by the rear energy that one is not merely focusing the forward energies, but the rear waves as well!
More accurately, one focuses the front wave launch while simultaneously dissipating the rear, or conversely, focusing the rear while dissipating the front. If the front baffle is placed parallel to the front wall, an identical dispersion pattern is set up, one firing ahead toward the hearer, and one firing up and out at the ceiling behind the speaker. Toeing in the speakers affects both planes of sound. Because of this the PureVOX is different from a conventional speaker in that the adventurous may even try widening the positioning of the front drivers beyond the parallel plane of the front wall, and in so doing narrow the dispersion of the rear drivers. I did not try it, but it should be known that because there is a second identical wave launch it is possible, and some listeners may find it to have an interesting effect, perhaps like a surround processor’s movie setting.
