Polk Audio Lsi Series - Manual (Page 2)

ANTI-RESONANT ENCLOSURE
Cabinet resonance can ruin the sound of an otherwise well-designed speaker. You don’t want to hear your
speaker cabinets humming along with the music (they don’t even know the words), you want to hear the
uncolored sound launched by the drivers and tweeters. We take special pains to make sure that Polk speaker
cabinets are resonance-free. All wood cabinet Polk Audio loudspeakers are constructed of costly low-resonance
MDF instead of the cheaper and more resonant particle board used by many competitive speaker brands.
LSi models feature additional anti-resonance strategies such as asymmetric braces and resonance-
damping side panels (for 1 1/2" total cabinet thickness). See more about Anti-Resonant Enclosure at:
