I investigated the Vivid speakers. They are seriously competent. But I can't find anything about their filter alignments; I strongly suspect they are higher order, whereby they can more easily solve all the other design aspects and produce convincing music.If I had deep pockets, Vivids would surely be on my audition short list. But until then, I'm plenty happy with my 2.4s and anticipate being even happier soon!
My short list of best-ever speakers includes those with and without first-order filters, so uncertain how important that feature is to my ears. But I notice that since I moved up from mid-fi to hi-fi that I've only owned either Thiel or Vandersteen. Hmmm.
To be fair, domestic production and affordability were also factors in my decisions but I did prefer the sonics of the CS1.6 to the widely acclaimed Revel M20s, among other contenders. FWIW
