Just tuning into this interesting conversation now because I’m considering the CW IV’s.
I understand the various factors here. It is hard to see the logic of the CW’s not being improvable, unless the argument is that these speakers were designed without any price point consideration and they just happened to wind up at a mere $6k or so.
My guess is that if you found the engineers who designed these and got a few beers into them, they’d have all kinds of opinions as to how they would have perfected the design if they were allowed to spend more on parts or design. Note -- not what this or that user or DIY person wants to put in, but the designers themselves.
That could be wrong, but I’d be very shocked if they just happened to make the perfect speaker (given the design) at this price.
