15s can be optimal, but it's hard to integrate into car audio. The SQ of a subwoofer is related more to the motor design than the driver size, the driver size tends to control where the efficiency of the driver lies and where the resonance of the diaphragm occurs at. A 15" isn't going to sound all that good above 60hz. There are also 10" and 12" subs that don't sound that great above 60hz, the JL W7, Adire Brahma, and RE XXX are all examples (highly regarded ones) of subs that get muddy above 60hz or so regardless of cone size, mainly due to the resonance of the high mass paper and poly cones that they use. As a general rule, I would never cross a 15" higher than 50hz. Most people that get 15s try to mate them with a typical 6.5" midbass driver, and it doesn't work well. Pair it with a strong component set, like some Morel Elate 9s, and you'll get excellent results. All about matching the horse to the course.
