OK, but can the RM6700 pump up the volume? In small to midsized spaces, it'll do just fine. Vanilla Sky has an especially visceral soundtrack, and the RM6700 never came close to inhibiting the film's wide dynamic range. Satisfied with this model's home-theater prowess, we sampled a few DVD-Audio discs. Doing so confirmed that the RM6700's midrange was flawless--detailed and harmonically correct--and the treble was smooth, airy, and fully extended. We're downright persnickety about the way sats and subs work together, but the RM6700's blend with the PSW350 was absolutely perfect, causing the whole system to sing with one voice.
We briefly compared the RM6700 to the RM6600, and the engineers' recent handiwork was readily apparent. Oddly enough, even though the 6700 is almost exactly the same size as the older model, it sounds bigger and warmer, courtesy of the new Power Ports. The 6700's more robust bass response made for a better match with the sub.
Polk Audio offers a bunch of first-rate speaker packages, ranging from the $549 RM6000 to the $1,995 RM7600. The RM6700, which sits in the middle of the line and carries a $720 price tag, is another winner. We recommend this kit without reservation to those with small and medium-sized rooms.
