Alpine Type X 10" ported box size help
 

I have heard the alpine specs are not sufficient for the maximum output for this subwoofer..

Can anyone that has first hand experience with this sub shed some light on what size box works best in terms of loudness but still maintaining good SQ?
Specifically 10 inch type x... Not 12 inch... (the amp is a PDX 1.1000 which is mono 1000 watts)

What size Ported Box works best from your experience?
1 ports or 2 ports how deep? and how wide?

Thanks in advance !
