I'm finding the KP-100S the idea PA for all my smaller acoustic combo style gigs (less than 40 people) and which usually requires quick setup/breakdown. It's especially good used with no onboard speaker keyboards as the KP-100S & KP-200S design can provide both the sound to the audience as well as stereo monitoring to the performer as well. I'm finding the bass response on the KP-100S sufficient for intimate acoustic lounge music in smaller rooms. For added bass omph, I just grab the the Tyros subwoofer (with built in handle) and place it under the kb. The KP-100S performs double duty as an 'onstage monitor' for larger venues with the EV SxA100's acting as the mains. I'm really happy with the versatility my current kb/pa setup offers.
