Sound quality: Sony's SRS-XB13 had Good overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. Bass has little impact, is subdued, and deep bass is lacking. Midrange is fairly even, but is somewhat grainy and a bit hazy, and etched. Treble is fairly extended, but is somewhat prominent, sizzly, smeared, and dry. Does a so-so job of recovering room ambience and sounds a bit congested and constricted. The sound field extends somewhat above and to the sides of the speaker enclosure and is monophonic. When two units are used as a stereo pair the sound stage can be made wider depending on placement. Provides a decent volume level in a small sized room, and is best suited for near field listening.
