A 1 meter anechoic on-axis plot does not tell the complete story of how a set of speakers will sound but should not be ignored depending on what you are looking for.
In the case of this speaker, looking at the wider peaks and valleys tells part of the story.
There will be a noticeable bass bump between 40 and 100 Hz which many people would enjoy. There will also be a noticeable dip in the harsher frequencies centered at 3Khz which will make it sound smooth and in-offensive. The rising frequency shelf at 10 to 15Khz will sound bright on axis and create false detail but can likely be managed with blending through listening distance as well as aiming them off axis.
I bet these sound pretty decent and would certainly not rule them out based on that response plot.
