The sound quality is better than anything else, and the distortions are lower.
I know you like big old wardrobes, lindsayt, but they have big old drivers in them which are simply not as good as leading-edge new designs of drivers.
I know some like mega-bass, seemingly no matter how distorted (do you drive a Citroen Saxo ?), and electronic low frequency sounds are popular in some films. Those speakers in the picture are able to drive an LFE Sub, or stereo subs, if you wish, by reducing their bass output with a switch, but for music they simply don't need it.
