These speakers are made to match the LEB-405 speakers also sold on Overstock.
Like the 405's, these are just the entry level SDAT speakers, and while they look nice, they feel a litle cheap, but the sound quality is much better than the build quality and I don't think anything in this price range can compete with the sound of thes speakers.
I bought the Beech colored model and my wife loves the look of them.
If you buy the 404's and the 405's then you have got a perfectly voice-matched 5.1 suround system.
I used these to replace a more exspensive Sony system and am always please at how loud they can get when the movie soundtrack or musice demands it. I have never heard any distortion out of these. The driver quality is without a doubt superior to Bose.
I use a subwoofer, but these do put out very warm sounding bass on their own. I seriously doubt that these produce frequencies as low as 20Hz, but very few speakers do, and they certainly cost many times more than these do. In reality, most musical bass that we hear rarely if ever go lower than 40Hz, so this isn't a problem. Besides, like I said, My subwoofer nicely fills in the extrem bottom range of any soundtrack.
