Zvox 670 review Very happy with improvement of TV sound in sd-1 setting, and the much increased clarity of speech compared with TV's built in speakers. For bluetooth music listening of "aac" music files from my smartphone with aptX from PowerAmp, excellent transparency of sound is obtained in "accuvoice" setting - especially for fine voice singing, and very good in sd-1 setting. We don't use the other surround sound settings sd-2 & 3, because our priority is sound clarity, and increased surround sound effects come at the cost of reduced clarity. CAUTION: this unit can generate a strong bass sound, much of which radiates downwards before dispersing. The resonance of the surface that the unit rests upon will significantly affect the tightness of the bass you hear. In our case, the TV stand top was a 5/8" board spanning 36", and this resonated badly, muddying the bass sound. I greatly reduced this unwanted resonance and much improved the sound quality, by gluing a panel of 3/4" plywood to underside of the top of the TV stand, to stiffen it. Unit setup is simple and remote control operations straightforward and useful - most parameters can be adjusted from remote, e.g. bass, treble, surround sound, input source etc. Construction quality seems solid (wood cabinet) and good. The built-in amplifier is low noise, accurate and clean, power more than adequate for most listeners & rooms. In our case, the black Zvox 670 is an exact fit over our black tv stand, has no exposed cables and looks great. The soundbase unit readily doubles as a very good stereo system with blu-ray player and tv plugged in, and music also sourced via bluetooth from smartphone or computer. For half the price of one good loudspeaker you get a lot.
