Sound quality: Altec Lansing's HydraBlast had Fair overall sound quality - this model has sonic shortcomings that leave a lot to be desired when listening to music but don't rule it out for dialog. Bass has so-so impact, is somewhat subdued, and lower bass is lacking. Midrange is fairly even but is grainy and a bit muffled. Treble is fairly extended, but is somewhat smeared, a bit sizzly, and the lower- and mid-treble is somewhat subdued. Does a so-so job of recovering room ambience and is congested. 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 to medium sized room; at its loudest volume levels, the sound becomes a bit strained.
