Summary: I have owned the Onkyo S9400THX setup now for almost two years and can safely say it was an excellent purchase. The sound quality is excellent and the setup was relatively painless. The side and rear speakers sound good but the build quality is what you would expect from a 7.1 THX certified system for under a grand. I was very impressed by the quality of the front and center speakers, they sound great and feel sturdy.
Summary: ITS BEAST a BEAST of sound while playing videogames and movies. THX enters at volume level 82.. i almost never get that loud while playing it would be suicide i m around 65 70 at that pretty loud. Currently have it with my xbox one and i play a lot of BATTLEFIELD 4 . its simply amazing.
Excerpt: We installed the HT-S9400THX Home Theater Receiver by Onkyo in our theater and were blown away by the quilty of the sound. We matched this up with the Panasonic PT-AR100U Full HD Projector and feel like we now have a great theater package. Very happy with this unit. Depending on the movie you will have sound coming from all directions.
Pros: Clear Sound, Easy To Set Up, Good Remote, Thundering Bass
Excerpt: I know, I know -- this cannot compete with a $5k+ system where each component is given careful thought. But it is not meant to, either. This system, out of the box, is about as good of a Home Theater system I have had the pleasure of experiencing. If you are looking for an affordable way to acquire that in-home, small-room, theater feeling -- you can't go wrong with the Onkyo S9400. Sound is crisp and detailed. The spectrum is broad and balanced.
Pros: Clear Sound, Easy To Set Up, Interfaces Well With TV, Intuitive Controls, Thundering Bass
Summary: When getting ready to purchase a 7.1 surround system read more than a few disparaging reviews about this system. But went with what it offered in so much as THX certified sound, along with the speaker package included and power. I can happily report the system sounds better than advertised, setup using the provided sound analyzer and microphone was a breeze.
