Sound quality: Klipsch's GIG XXL had middling overall sound quality - this model reproduces music and dialog reasonably well despite the obvious shortcomings in its sound. With bass boost set to off to provide the most even tonal balance the bass has good impact and goes deep, but is a somewhat prominent and boomy. Midrange is fairly even, but is somewhat grainy and hazy, a bit dark, and is a bit overwhelmed by the bass. Treble is fairly extended, but is a bit subdued and smeared. Does a decent job of recovering room ambience, but sounds somewhat congested. When two units are used as a stereo pair the sound stage can be made wider depending on placement. There is no significant difference between Bluetooth and Aux inputs. Provides a decent volume level in a large sized room.
