Dude, don't even consider LCD speakers. Not unless they are some rather high-end ones like some of the larger screens have. I once had them wired up has my center channel, but their horrible range threw everything else off and it sounded much better without them.
Now some are decent. I have heard some that had a very nice, full range. Others had great treble, if you have another set of speakers going or whatever. But most are simply an 'added bonus' that's not even worth mentioning

it's more of a selling point than a real feature. Sort of like a 7300 with 512MB ram
