Here at Audioholics we like big home theaters with lots of speakers surrounding us. However, we do acknowledge that there is an occasional need for a more simplified 2-channel home theater system. As such, LG has introduced the LFD790 which includes 2 speakers, a sub module, and the DVD / receiver component. There aren't too many options for 2.1 systems these days unless you are looking to build your own setup from individual components, so it's nice to see a low cost and easy to use system on the market.
The LFD790 home theater system has a very polished look to it. The glossy finish, hard edges, and pleasing top display make it very classy indeed. The main unit contains the DVD player and some of the electronics, but the display is on top, not the front.This seems a little odd at first, but the iPod-like touch surface on the top necessitates that the main display be there as well. On the back of the main unit is an HDMI port for 480p, 720p, or 1080i output, and there is also a proprietary cable for hooking up the subwoofer module. The actual amplifier circuits and inputs are not contained in the main component, but in the sub. Clearly, LG was trying to keep the DVD player as small as possible so it could be placed on an open shelf next to the main display. The inputs are fairly well organized and should be a breeze to hook up for even novice home theater users. Again, the speaker outputs are also on the back of the subwoofer and utilize a proprietary connection, so future speaker upgrades won't be possible without some custom modifications.
This system can typically be found for around $100 off the MSRP and has a pretty good sound quality for the price. The speakers are fairly clean for dialogue, and sound pleasant as long as the volume isn't too loud. Crank it up and you'll get the telltale distortion inherent in these smaller systems. The sub produces a good mid-bass thump, as well. We can certainly recommend this system to replace ANY built-in TV speakers that you'll find in the typical flat panel display. Also, the sound quality is probably better than that of a similarly priced surround sound HTiB. Speaking of surround sound, the LG does have a few virtual surround modes, but they didn't really produce a convincing surround feel. Stereo sound was our preference. Also, the easy on-screen menus and well laid out remote control were nice touches for an entry level system. So, if your room layout doesn't allow for multiple speakers and you are looking to spend less than $300, then give the LG LFD790 a listen!
