Carbon Fiber is an expensive material and very time-consuming to do properly. And very difficult to do at scale. If you want to see what's involved in making CF parts, I recommend spending some time on the Easy Composites YouTube channel
Are carbon fiber speaker cabinets inherently better than wood or metal ones
