Both soundbars feature the same internal components including a trio of 3.25” full-range speakers that create a virtual surround experience, and a 4” powered subwoofer.  While the subwoofer will produce sounds as low as 43Hz in the ZVOX 440, the smaller cabinet size of the 430 means a range that bottoms out at 48Hz.  The 430 is shipping now at a price of $449 and the 440 can be expected at the end of September for $549

Also announced by ZVOX was a pair of soundbases: the Z-Base 525 and the IncrediBase 575.  Essentially a smaller version of the Z-Base 550, the Z-Base 525 is designed to work with smaller TVs and with a size of only 24”L x  12.5”D x  3.5”H, will fit nicely on a standard bookshelf.  For integration not only as a speaker, but as a display base, the Z-Base 525, shipping now at a $399 price point, is also being touted as a sound option for PCs.

The big boy of the bunch is the ZVOX IncrediBase 575.  Featuring five 2” full range speakers and a pair of 6.5” subwoofers, the IncrediBase offers bass response down to 35Hz.  The IncrediBase takes a bit out of the economical appeal out of the sound bar option however, with a MSRP of $799.99.
