Ok, I left out the part when talking about "loud" involving quality.
Picture an athlete scholar who is tasked with running while solving math problems. The speed he runs represents how loud the speakers will get, how efficient they are. His ability to do math, while under a given stress, represents audio quality of the sounds produced.
The scholar, and the 110 speaker, can perform much better loafing along, not stressed by running hard (higher volume). But when our weak scholar is tasked with sprinting, he starts losing concentration and he performs math poorly. Likewise the 110, even if it can reach the desired decibels, would be shown to produce distorted sound.
Another scholar athlete (Klipsch) is in better physical condition. He does pretty good at a walking pace, and he maintains all his mental faculties when sprinting a 400 or running a marathon.
Besides lack of distortion, there are number of other factors in play: like the directivity of the speakers.
If the space's interior is reflective, the Klipsch might sound better because it has a more narrow dispersion pattern and directs more sound at the listeners and less at your walls.
