Setting up a subwoofer

I have a James EMB-1200 with B&W 803s as my main speakers and an AVM-20 processor. When I set the subwoofer level using pink noise from the AVM, I must set the gain on the subwoofer to near max volume (the james has a 1200 amp) to get a consistent read on my Radio Shack SPL between the 803s and the sub.

When I play bass-intensive soundtracks like Lord of the Rings or Star Wars, the bass is overwhelming and the subwoofer gets close to bottoming out.

My question, is there a more accurate way to set the subwoofer level, or is it that movies like Star Wars and LOTR are just over-the-top bass intensive?

Thanks!

Appreciate your thoughts! I never gave it much thought that I might be measuring with the SPL in a null node. I only have 3 positions with which to place the sub. two are on the same plane as the main speakers. The third is on a wall perpendicular to the mains (about 10 feet away). I'll give this third spot a try.

Also, any thoughts on using Outlaw's ICBM outboard bass management system or Velodyne's SMS-1 bass EQ in facilitating subwoofer placement and integration?

Thanks!
