The Zvox Z-Base 575 (along with the step-down Z-Base 550 and Z-Base 525) tackles both of these deficiencies in a clever way: the speaker is shaped like a large black box that acts as a second pedestal for your HDTV. That makes the Z-Base "disappear" on your TV stand--a remarkable feat considering the Z-Base's rather large size. That size contributes to the Z-Base's capability to fill a large room with sound; its powerful bass was better than any other sound bar we've tested that lacks a separate subwoofer.
The Z-Base 575 does have its shortcomings. For instance, the feature set is minimalist, and competing systems offer significant feature step-ups, like HDMI switching on the YSP-3000 ($800 street price) or digital audio inputs on the Denon DHT-FS3 ($450 street price). However, if you don't need the extra features, dig the Z-Base 575's minimalist design, and need big sound, the Zvox Z-Base 575 fits the bill.
