Right out of the box, I should say that among home theater in a box systems, the Onkyo HT-S9400THX is arguably the best deal on the comparison chart. The features you get for the money you spend weighs heavily in favor of it's features.
In the box of the Onkyo HT-S9400THX, you will find the following components: an AV receiver, seven different speakers and of course the subwoofer. I were impressed at how easy it is to set up this system. Where to place each speaker in any given room is easily found. The system includes a microphone that detects where you place each speaker. It then calibrates the system to that certain setup, giving you an optimum listening experience no matter the setup you choose.
The THX on the end of the Onkyo HT-S9400THX indicates that the system uses the THX standard for its surround sound experience. Millions of movie theaters around the world use the same standard. Bringing THX into your home is never considered a mistake. Onkyo did a great job building this powerful sound system into its quite small speaker system.
One drawback to the Onkyo HT-S9400THX is that it does not include a original DVD or Blu-ray player. It's perfectly compatible with a vast majority of the players on today's market though. However, an integrated player would ensure that the system's settings and controls are best suited for that particular player. You can achieve the same effect, but you have to mess around with the menus and settings for a little while.
A cool feature of this system we should mention is that you can use your iPhone as a remote control for the Onkyo HT-S9400THX. All you have to do is go on the app store and search Onkyo, and the first result should be the Onkyo Remote app. It's free and is a great tool to get, especially for those who are always losing remote controls.
Connectivity features on the Onkyo HT-S9400THX leave little to be achieved. It boasts four separate HDMI ports. Therefore, you can connect multiple HD devices to the system simultaneously. Other options include the very good composite, component and coaxial connections for analog devices that utilize the analog signals.
The Onkyo HT-S9400THX posses the ability to stream content straight from the internet. All the popular streaming sites such as Hulu, YouTube, Pandora and more are available right from the system's menus.
