TV's of the last TWO decades suffer from a lack of audio speaker enclosure physical volume. One can only EQ up to a point. A console tv set in the 1960's had enough physical size for a reasonable resonant speaker system. Modern day sets rely on electronics to eq a set of effing 2, MAYBE 3" drivers in an array to simulate the effect of a full size speaker get closer. But, guess what? They fucking DON'T! And never will. Plugging in a decent amplified sub-woofer helps. That allows those smaller drivers to focus on the freq range they should (and that's NOT the same thing as "would") be expected to support. However it still doesn't solve the problem. Mother Nature can only be fooled up to a point... There are unavoidable holes all through the audible spectrum from this approach usually. Only way to avoid that is to have a microphone out in the listening area. THEN someone with a clue can work to complete the room's eq. A classic example of fixing a likely non-existent problem, for anyone other than a bean counter. Those big boxes that make speakers GOOD are expensive to produce, and also take up room in the listening area. Where is the knee of the nexus? And who do we consumers (that might have a fucking clue) trust to define that point as an automatic generalization? That won't be me. Ever....
