My JL Audio 10W3V3s require .62 cu. ft. per sub, my box supplies .70, polyfill?

Is there anything wrong with having more air space than recommended? With what is recommended and what I have, should I use polyfill? Will it make any difference? How much should I use if any?

My box has a total of 2.117 cu. ft. minus the woofer displacements, for a total of .70 per sub (3 subs).

Thanks!

Anyone? Should I use polyfill or not?

Polyfill is used if you have A LACK of airspace. Your box is fine.
