An added bonus is that of the AMD physically safeguarding the dome if your kids have like to play football in your listening room, at least they won’t be able to nuke your tweeter.īlack ash vinyl clothes the VR12, while the drivers - mounted on a 1in thick hardwood composite baffle which is raised and bevelled to avoid diffraction problems - are covered by a grille-on-a-frame which is designed not to interfere with dispersion. Drilled through it are five hollow tubes which attenuate specific frequencies to eliminate unwanted resonances. Fixed vertically to the front of the aluminum dome is the AMD (Amplitude Modification Device, patent pending), which acts as a mechanical acoustic filter. Dual woofers provide the symmetry by flanking vertically-mounted treble and mid drivers.īoston’s Lynnfield Project research, which resulted in a $5000 speaker system, has trickled down to the VR Series speakers the tweeter in particular shows how the company adapted high-end features to the more affordable models. Instead, drivers were developed appropriate for fitting into a shielded, TV-set-friendly 8.75x25x8.5in (HxWxD) enclosure. Boston Acoustics has actually taken the more difficult path of not merely flipping one of its speakers sideways (after making it symmetrical, that is). I love this flouting of surround-sound’s status quo. So the VR12 is not quite a VR speaker on its side, but a truly dedicated center model. And the VR12’s two 165mm woofers? They’re also unique, because the others use 180mm woofers. The three full-range models (VR20, VR30 and VR40) share the VR12’s 25mm anodized aluminum dome tweeter, but this three-way unit has a 115mm copolymer midrange when the only other VR three-way, the VR40, uses a 135mm driver. Weren’t we told time and again that the three speakers across the front should be identical ? You know: all that guff about what happens when someone on screen is speaking while walking across the picture? And how the sound quality shouldn’t change one iota?Īnd yet here’s Boston Acoustic’s $400 VR12 center channel speaker, an upscale model in the Lynnfield VR Series, which has no exact equivalent in the range. Still wary of this industry’s THX sermonizing, I’m at a loss to explain but happy about the proliferation of center-channel speakers that are something other than horizontally-mounted versions of a given manufacturer’s main left-and-right speakers.
