We sold Polk Audio for years until they became Sound United. Mrhookup nailed a lot to take into consideration. Matthew Polk made amazing stuff. Personally, when they started selling in Home Depot and Amazon, we took a stance not to sell them any more. We have moved onto Klipsch and so glad we did. Klipsch is an extremely efficient speaker needing very little power to create amazing acoustics. For in ceiling speakers, consider using the dynamat Dynabox behind them. They create a back box for better sound and remove any noise bleed
