Point source, yes, absolutely, at least in their LS50 with no other drivers. But that's only one non-essential attribute of full-coherence. Vandersteens' achieve it all without any concentric drivers. All Thiels except the SCS4 (?) have the wide-bandwidth woofer (and sometimes other drivers too) some distance from their coax mid/tweet.
I just bought a pair of LS50 Metas to supplement my 2.4 due to a hypersensitive deranged neighbor (no lower bass output and lower volume capabilities), but need more time for a thorough A/B to get the true measure of them, as my 2.4s over the past decade have become my reference in my long-term acoustic space.
I'll report here when I can arrive at firm conclusions, as xyzsantabarbara loves his previous-gen LS50s and his 3.7s, and the Metas are getting serious accolades, many that I can confirm are compelling and actual.
