A word of caution, Ohm no longer uses genuine Walsh drivers, and hasn’t for some time now.

jazzman7: The KEF Uni-Q would seem to disqualify itself from this discussion due (at least) to their use of a second-order crossover. Indeed, the step response plots from Stereophile look nothing like a time/phase coherent loudspeaker: https://www.stereophile.com/content/kef-ls50-meta-loudspeaker-measurements |
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. |
