Sony is typically known for their higher end consumer electronics, at least that's what the big box salesman will tell you as he shows you the price. This is certainly true sometimes, but let it be known that Sony can make entry level products with prices to match. Enter the HT-DDW790, a very low cost 5.1 home theater system. This unit is very basic and comes with a full size receiver that has only a few inputs, 6 speakers with wire, and a remote control.
When I say basic, I mean basic... Just check out the back and you will see only 2 digital inputs and 3 stereo analogue pairs. Yes, there are AM/FM antenna inputs and speaker spring clip connectors, but that's it! No video switching of any kind... just one big empty backside. Fortunately, Sony just lowered the retail price so the lack of ports shouldn't be a concern for those simply looking to get surround sound without all the fancy features.
The included speakers are pretty small, but sound fairly clean in the vocal range. They are certainly better than average TV speakers but can sound harsh if the volume is too high. Also, since the amp is rated for 6-ohms, it should be able to drive some larger speakers in the future should you choose to upgrade, but low-efficiency speakers will likely result in distortion when played at even moderate levels so be careful. The included subwoofer has an 8" passive driver. It's rare to find a sub this large on such a low cost HTiB (Home Theater-in-a-Box). It has a good mid-bass sound to it and is fairly compact. It would have been nice if Sony had made this a powered sub and put a standard subwoofer output jack on the receiver to make an upgrade easier.
In any case, the DDW790 has a few good components to get the new home theater user started. With the ability to add the components you want and upgrade speakers later, it's a pretty decent value. And remember, next time your big box dealer says Sony is top-of-the-line, run 'em over to the HTiB aisle and point out that they support entry-level consumers as well!

The sound of it is slightly better than one of those console (non-portable) boomboxes. It has no banana clips–only spring loaded pressure clips for that what? 24 gauge speaker wire. The receiver does accept full bit-rate DTS over coax and toslink. This is an issue for people w/ 2nd generation HD-DVD players, since the players convert high res audio to DTS. The tuner? It's a tuner. Stations come in clearly. It is fine for movies and (just) okay for TV. The auto calibration isn't great. However, Tom and Dina would tell me to stop listening to their podcasts and use a SPL to get it right. (Yes, I listen.)
It's not a horrible system. I wasn't too happy listening to classical or jazz with it. However, I heard all the bass via the Transformers HD-DVD without issues.
My major complaint is its size and that it only comes in silver!
