Pill.. first I heard. The main living room has a 15' cieling. Got an LED Samsung the speaker was $hit sound bouncing off wall, couldn't get it loud enough to hear dialogue. Got a Samsung sound bar 5.1 series with center speaker for dialogue. Big improvement , I thought I was going to have to use close caption. A lesser man would go mad with the constant high frequency hum. Sucks. Last assignment in the plastics factory I couldn't push the plugs in far enough. Muffs with a hard hat we're worse when I got overheated.
