Carbon fiber is a great material for many applications because it is both light and strong. That said, no material has been more overhyped in recent times, and used to make all kinds of junk, from cup holders to toilet seats. But do they use it to make acoustic guitars or violins or a bass viola? That would make me skeptical that it's a superior material for speaker enclosures. I'm sure it's a great sales gimmick that adds lots to the cost of a product that is likely to be priced extra high as a result. But better for speakers? Naw, it's just another material, and like others have said, you have to account for its strengths and weaknesses just as with any other material. I think it is way over-hyped but I'll tell you one thing that I just bought that really benefits from carbon fiber- a photography tripod-- where its strength and light weight really makes a difference. I don't find it all that attractive usually, so it would not be my first choice for a speaker enclosure unless it was painted or coated with something.
Are carbon fiber speaker cabinets inherently better than wood or metal ones
There seems to be a pretty big jump in speaker prices when moving to carbon fiber cabinetry when all else is equal (or what seems like equal). Is this because it is able to be molded into more acoustically correct shapes or simple the characteristics of the material?
