big sub small coil?????

OK so I'm here scrolling through the forums and someone posted a sale going on at wooferwarehouse so I decide to check it out and notice they are selling some 21" incriminator audio warden subs but as I scroll through the features it says it only has a 3" coil that is supposed to handle 3500 watts RMS. But then I remembered that the mtx jackhammer 22" had a 6.5" coil that can handle 4000 RMS. Is there something I'm missing here? I'm just trying to understand what the difference is other than the coil size. Take note I do not intend to purchase either I'm just curious as to why they would have a 3" coil in a 21" sub

Coil size has a lot to do with how much over power(clean) said sub can handle

It also has to with how well the coil will cool. Not very many people own the MTX. 3 to 4 inch are normal for high powered subs. I prefer the 4 inch myself. Easy to find drop in replacements when you do a recone.

This is true but I have seen 12"s with 4" coils so I'm just thinking why would a 21" only have a 3"

Because they used an existing basket from another sub that did not require the larger coil.
