Hi Derek!
If your using one PR, then add no mass - its 400g moving mass as it is is perfect. If your using two PRs, you'll need to add an extra 300g to each driver. These figures are correct when using a 30L box. Using two is reccomended.
You can use just about anything for the weight - but washers work well, and are easily available from all hardware stores. There is a screw-thread on the back of the PR which allows you to add mass. Or simply ask the distributor to add the mass for you before they send them off.
I'll post the schematic here for the EQ circut once I can upload to my ISP again. At the moment it wont let me :(. Or I could email you if like, just post your address here.
Adrian
