| Well-balanced, reasonably priced floorstanding loudspeakers are not easy to come by, but Infinity's Reference Series RS-4 is a great example of dynamic, nearly full-range loudspeakers that don't require a second mortgage to enjoy. On the Infinity RS-4 speakers, music ranging from rock to classical and new age sounded equally at ease, with acoustic instruments and voices sounding especially full-bodied and natural. We were immediately impressed with the high sensitivity of the RS-4 speakers: At 90 dB, even small integrated amps or receivers can drive this system toward its 112- dB limit. Even under dynamic duress, the Infinity RS4 system maintained its "snap" and punchiness, never flattening out or congesting at the loudest passages of our test material. At its loudest, the RS-4 system got a bit "peaky" in the high frequencies, and the highs in general sounded "harder" or more metallic than those from better, higher-priced speakers, but these qualities pale beside the RS-4's considerable strengths. The RS-4 imaged well and its bass extension was strong, commanding decent--and clean--low frequencies even in smaller rooms. Used with a powered subwoofer, the RS-4 kicked even lower, but the subwoofer was by no means necessary. If you're looking for a well-rounded speaker pair to upgrade your music system or start building a home theater, the magnetically shielded Infinity RS-4 speaker system is a fine place to start. Pros:
High sensitivity Good tonal balance Strong dynamics Easy placement Cons:
High frequencies slightly "hard" |
