home theater subwoofer wiring

Do I have a home theater right?
I have a 52 "Samsung Touch of Color LCD TV (LN52A650), PS3 for Blu-ray and games, an Xbox 360 for games and streaming Netflix, 7.1 channel Denon AVR-1909 receiver, 4 Definitive Technology ProCinema 800 speakers (2 front, 2 in the back sitting on Definitive Technology ProStand 800 speaker stands), Definitive Technology ProCenter 1000 center channel speaker and a Definitive Technology Supercube III 650W 10-1/4 "subwoofer LxWxH.'m using cables HDMI and speaker wire gauge 14 W / banana. Is that a good home theater? Personally, I have received many compliments from people surprised by the sights and sounds of my home theater. I was wondering what others think here of my setup.
It is good if it looks and sounds good to you. No matter what anyone says. Ultimately, is your home theater system and you should be happy with it.
