What if a high end speaker measures really badly?

I would quote Darko… there isn’t bad audio gear, just mis-priced gear.  I like deep_333’s philosophy, an exceptional price requires exceptional novelty on the part of the designer / manufacturer.

My experience is loudspeakers sound like their defects.  Some of those defects we can see very clearly in measurements.  Some defects sound good in the short term and can fool us.  Some people like being fooled… others regret it.  For comb filtering-like responses certain notes will align with the comb peaks, others with the comb valleys, giving an impression of detail and excitement.

It seem likely this speaker will be very much a matter of taste and may require a lot of setup time to get it right for your listening space.

I will no longer consider a speaker that has not been independently measured.  It is not that a good set of measurements guarantee a good sounding speaker.  I am looking at the measurements to understand the designer's background and motivation.  I want the speaker that the designer made for himself through a combination of good engineering and listening evaluation.  As opposed to made per the marketing department, or worse was designed by someone in the marketing department using a newly purchased copy of the Loudspeaker Cookbook.
