DAHLI
Damped Asymmetric Hex Laminate Isolation (DAHLI) Cabinet Design for clean, accurate
sound. The asymmetric design is made from a 6-layer laminate with 5 viscous layers to create
the Optimal Shear Damping (OSD) system. The process was specifically developed for Polk.
Their elegant styling aside, creating curved cabinets not only results in a stronger, more rigid
and acoustically insert enclosure, but the curved walls also produce less audible coloration
from panel resonances.
