Why do they have 4" voice coils? The rated power handling is only 1200w, wouldn't a 3" voice coil suffice?

There are certain advantages to using a 4" coil, even if the powerhandeling isn't going to be huge....

There are a wide variety of factors you could consider....

For one, the same length of wire on a 4" coil with a shorter winding height will have less inductance then it would on a 3" coil with a taller winding height... or if you keep the winding height the same but vary the wire gauge the 4" coil will dissipate heat better and still have a lower inductance... ect...

Correct me if I'm wrong on this, but I thought 4" vc tended to not to sound as good on music as say 3" coils.
