As you say, these are simply claims/marketing with no proper measurements. However, it's possible to see how traditional line arrays perform in several of the papers in the links below. Bottom line is that line arrays suffer from polar lobing, comb filtering and poor directivity.Unfortunately, these are all generic specifications that you would get with any manufacturer. And we all understand line source tech. A lot of other speakers also meet my requirements, that's not really the point. The point is to have objective data for all the systems that meet requirements, and to find the best one for my needs. These audio companies (wisdom et al) do not seem to provide anything other than some specs and blurbs. Thus apart from listening (which is notoriously unreliable even in your own room much less a showroom) they make it impossible to evaluate and compare with other speakers. Spins are needed, and failing that, at minimum on and off axis responses, as well as directivity charts for the speakers in question.
But I want to point out that complete measurements is what's needed, not spinoramas. Parts of spinorama is an interpretation of data and some are highly discussable. To put in another way: Would you rather see the complete results from a medical study where you can draw your own conclusion or only see the interpreted results?
