Sound quality: Sony's SRS-XB23 had Good overall sound quality. In stereo mode and positioned horizontally, the bass has decent impact but is somewhat subdued and the deep bass is lacking. Midrange is fairly even, but somewhat grainy, and a bit hazy. Treble is fairly extended, but somewhat smeared and a bit sizzly and subdued. Does a so-so job recovering room ambience, and sounds somewhat congested. Other than losing the minimal stereo effect when switched to Mono mode, there is no significant difference in sound quality between modes in either horizontal or vertical orientation. When two units are used as a stereo pair the sound stage can be made wider depending on placement and the stereo image becomes more apparent. Provides a decent volume level in a medium sized room but gets harsher at higher volumes.
