I asked B&C about their cone profiles, here is the answer:
'Hello,
Both radial and exponential definitions describe a cone with a curved side. We generally refer to a cone with a less pronounced, sometimes almost straight, side curvature as a radial cone, distinguishing it from the more curved exponential type.
In general, straight or radial-sided cones tend to be stiffer, while exponential flared cones often provide greater high-frequency output.
However, the presence or absence of cone ribs, paper pulp composition, thickness, and other factors significantly influence a cone's acoustic behavior. Cone shape is just one aspect to consider.
Ultimately, selecting the right cone is a designer's decision, balancing various specifications to achieve the desired loudspeaker performance.
