SPL meter subwoofer tuning


I have tried many different placements for 2 Von Schweikert VRS/1 subwoofers, however I still cannot seem to find a happy medium. I have heard purchasing an SPL meter will be very useful in setting up these subs in stereo. Anyone out there use an SPL meter, if so can you give me some feedback on how to use and how much help it will be and if it's worth spending the money on. I do have a disc with pink noise for a subwoofer. Thanks

I'm surprised you big buck guys don't advocate the use of Breul & Kjear (B&K) or General Radio (GR) sound level meters. Sure the Radio Shack unit might be OK for setting up speakers, but have you ever held and carressed a B&K meter? It's a truely sensual experience that's bound to add to your audiophile enjoyment. And think how impressed your buddies will be when you unload it from it's ever so nice case. Also it can re used with a remote mic and balanced leads. We had both B&K and GR in our lab, but the B&K is a much more emotional experience.

Stereo subs get extremly sticky without proper set up. Basically you normally have to run them out of phase to each other due to playing the same frequencies in 2 different corners end up canceling each other out, and then you actually reduce the quality bass load in the room vs. just cranking a single sub up... Now SPL meters are really not accurate in doing subs without a lot of extra knowledge and setup, test CD will be needed that is definate. Good luck
Thanks for all your responses, I have had success with placing by ear, I tried the SPL, it did help, however ultimately my ear was the deciding factor
