The DaCarbo large-bore trumpet features a carbon fiber bell that extends all the way to the valve casing. This is the trumpet I fell in love with at the NAMM show last year. It is a free-blowing horn that will take a lot of air if you need it--note that Arturo Sandoval is a DaCarbo artist!
The timbre is smokey and voice-like, yet it has amazing projection. Although a lot of attention goes to the hip-looking carbon fiber, I have found that the super light weight of the instrument and the lightening fast valve action are equally attractive.
Here are some other advantages:
Carbon fiber does not corrode and it is difficult to dent
Carbon fiber is stable and less affected by temperature changes than metal. This means you have a better chance of staying in tune on a long outdoor gig.
While it projects very well in a large space, its smokey sound also blends seemlessly into the ambience of a small performing space.
Great aesthetics. Did I mention that this trumpet looks very hip?
