Need to know driver displacement...

[Grimster74]

I have another thread going for my sub box build but I figured this would get more attention. I'm trying to figure out what the driver displacement is for a Polk Audio, MM2124 12" sub. Any help would be greatly appreciated.

So nobody has any ideas? For the time being I just used 0.10 cu.ft. just to get a rough idea of what size box I'm looking at BUT if anyone could get me the correct displacement, I'd greatly appreciate it.

You dont need it bro. .88 is how big the interior volume of the box should be before adding the sub. Design your box to .88 ft3 and youre all set.
