Installing new Denon 3802 this weekend. This HT is mainly to watch Satellite TV and sports and Satellite movies, occasional music cd but not in any way critical. I'm adding a Sony SAWM40 sub to compensate for old small rear and side channel speakers for the occasional movie and hopefully to enhance the sound of hockey players crashing into the boards. 1)Are LFE effects transmitted over the satellite signal? 2)What setup settings should be used (small rear and sides, good front main, cheap center), sony sawm40 sub? 3)What setup settings should I use so the Sony sub will not be on when I'm listening to a music CD? My front speakers are pretty good on their own.
