B&W design quality observation. Any downside


I just took the baffle off a pair of B&W Concept 90 CM1's from 1991. I wanted to tighten the woofer drivers to the baffle. I was surprised to find the spider for the woofer was cast in 1 piece with the front baffle! Certainly no tightening required.(It confirmed the B&W ethic of good quality to me. The rubberized/elastic seal between baffle and speaker was also in perfect condition. I was left to tighten the tweeters to the baffle and the baffle to the body-which made a very noticeable improvement to the clarity, dynamics and smoothness of the sound
I am impressed by this design; it seems sensible when technically feasible as it absolutely eliminates any chance of loosening from the baffle-which is the bane of ALL speakers where the drive units are affixed to the baffle.
I wonder why some of these so called "ultra high end speakers (Magico, Yg Acoustics) don't use this type of design.
Is there a downside I am not considering?
ptss
When I am at shows and I listen with my own music to the new B&W speakers I think; mannnn you don't want this!! That is why I demonstrate only 3-dimensional sound. I send people to shops where they sell B&W. That is how I use these speakers still. Only to let people understand what they will miss. This is a very simple and convincing way that 3 dimensional sound is superior to 2-dimensional sound. You have to keep things clear and simple in audio!
Ok, Bo, which brand of speakers give the 3d sound? I remember you poo-pooing the JBLs, but you admitted that you haven't heard the latest Synthesis models including the S4700s I currently use.
Today's infomercial from Bo is even more irrelevant to the OP's question than usual...
Funny I get 3D soundstage with any speakers in my system. I
always thought that it came from the preamp that I design and
build. I wonder, if I had Bo speakers I may get 4D???

Me make funny!!!

So true, however, I'm sure he just couldn't hold back. If you only read the title of this post, "B&W design quality observation. Any downside", that's like the straight man of a comedy duo giving a "feed" to his partner.
