Wilson's new speaker the Sasha is coming.

THere is a teaser on their website. Looks beautiful if you can make out the images. I think it is a step up from the WP generation. Maybe a replacement.

In reference to Mariv26 -- X material is a phenolic composite (not the same as an epoxy resin). X material is indeed extraordinarily rigid and very hard -- much stiffer and harder than aluminum. The waterfall graphs are but one type of scientific research Wilson does on materials -- but these graphs (despite your assertion) are very revealing of certain aspects of a material's acoustical performance. Wilson correlates these tests with blind-test listening comparisons. Certainly for Wilson, this test alone would indeed eliminate aluminum as a serious contender for speaker enclosures. But there are several other tests that reveal that aluminum is not a particularly good material for speaker enclosures. At least if the goal is to build enclosures that have the least sonic contribution to music. And the answer to the straw-man rhetorical question "why do you not see airplanes built from epoxy?" Again, X is not epoxy, but the simple and obvious answer is mass (weight). X is much, much more massive than aluminum and therefore would be unsuitable for the construction of airplanes -- where low mass is critical.

Dgad,

"Not sure if you are a Magico or YG fan"

I am neither. In fact I never heard them, but after reading Wilson spin, maybe I should. I was interested in a new loudspeakers, and having heard and liked the Sophia, I thought I will do some more investigating to Wilson other offering. I must say, as an engineer (Mechanical), I was mortified by some of the nonsense I read on Wilson web site. Regardless of how good the sound is, I can see now from where the high-end gets its “bad rap”. BTW, the functionality of a loudspeaker enclosure is completely opposite to a musical instrument one. A musical instrument enclosures role is to vibrate and amplify sound a loudspeaker enclosure need to do the as “quiet“ (but rigid) as possible.

Wilson employs a post-grad mechanical engineer, along with an electrical and acoustical engineer -- again, both post-grad degrees. I can assure you that neither of these credentialed engineers are "mortified" about revealing this aspect (just one of several) of Wilson's science. You are absolutely correct: a loudspeaker enclosure needs to be as quiet and rigid ass possible. X-material does these two things in combination far better than any tested material to date. The science indeed clearly supports this claim.

Mr Johnmaxx, thanks for joining in. So if aluminum is not a serious contender for speaker enclosures how do you explain the excellent decay plot on the YGA (http://stereophile.com/floorloudspeakers/yg_acoustics_anat_reference_ii_professional_loudspeaker/index4.html) and the hardly adequate one’s on the Watt (http://stereophile.com/floorloudspeakers/607wilson/index4.html)
