Using Polk 265-LS in-walls for left and right. I didn't want in-wall for the center, but I wanted Polk. The R300 is a great product. Well made. Sound is accurate and detailed at all volumes. Not harsh at all when pushed. A competitor's center with similar specs was huge. I didn't want a big center speaker, but I wanted big sound, and the R300 has it. Good stage and dispersion. Some center channels sound too loud, but not this one. Good purchase.
