Actually, thats seems like an interesting question. Anyone know why the round cone shape dominates most subs?

It has to do with the resonating frequency of the sound waves. Think of a drop of water in a bucket. The wave is produced in a spherical manor outward. The same principle applies to sound waves. Your speaker produces resonance as the wave reaches the end of the cone. It is kind of like resistance at this point. The higher the resonance, the more distortion that is heard and the harder it is for the speaker to operate. Your surround takes alot of punishment from this. This is why they have to be fairly strong material. A square cone produces much more resonance on the surround and corners. For sound quality, you never want a square cone. When it comes to bass, the extra cone mass is a advantage. However, the added strain on the surround means that the material must be stronger and sacrifice flexibility. This is why kickers subs were known for blowing surounds. As the surround was beefed up, the sub lost efficiency and pretty much nullified all advantages it had for added mass. In short, the square sub costs more to make, requires more wattage for the same spl, and get its ass kicked by a round sub of equal or lower ratings.
