Well first things first

Welcome to MBWorld

Now to the rest;

You can always STFF for this info

or

You can measure with a ruler and a DVM. The fact that it is sitting in the open should tell you its the free air variety.

 

c'mon more replies please..

 

welcome

 

Actually, amdeutsch gave you the answer you need - the first word in "STFF" being "Search." You can guess the rest. Subwoofer replacement has been addressed A LOT! Including by jbondox.

And what better way to determine size than to measure?

 

use a voltmeter to measure the ohms resistance. a reading of +6 would indicate a 8-ohm sub, which is probably what they use! but use your voltmeter to be sure!
