Samsung HW-Q67CT Dolby Digital 7.1 Theater System

Bought a refurb set. Didn't sound too good with connecting the sound bar's Bluetooth to my LG TV, but it did pair easily. The audio was there, but the bass really wasn't at first. Had to really crank up the sound to really get some bass response. Switched to the HDMI ARC in/out from my TV and the sound amplified quite a bit. After that it was just a matter of tweaking and fine tuning the internal EQ, speaker placement and levels. I don't know if the subwoofer is self amplified, but at the levels I was running it, it didn't seem to clip. FYI, it's a ported enclosure.In general the system is both satisfying in terms of going loud and staying clear. I'm really happy with it, I only wish the subwoofer had its own crossover level.----------Update 2 weeks later:Although using the HDMI ARC sounds more amplified than the Bluetooth, the sound levels are just way-way off. The rear speakers are much too loud even at the lowest level setting, the sub is very sensitive, and the center channel is really hard to hear, especially with soft spoken voices and when there's dialogue during action scenes. I prefer not to use subtitles, but have had to turn them on more frequently now.Last option was optical, which reviewers already said no good to, but My TV can play both internal speaker + optical simultaneously. Going this route allows me to independently control the TV and the sound bar volumes. It took some back and forth tuning, but finally found that happy medium, but to watch the movies loud, the sound bar does need to be cranked up more than HDMI ARC, when using optical.
