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
SPL meters can get you kindof close but it really takes tuning by ear. When "perfectly" flat response is acheived according to the SPL meter it usually sounds bad. There is a formula for correcting the RadioShack meter that can help (search archives). If you want to measure inroom response you will need a disc with worble tones. This plays a tone that varies within a small range continuously to eliminate the single tone building up and resonating within the room which would give a false reading.
Placement flexibility is the biggest obstacle though. Get a 10meter generic interconnect (less than $20) and place the sub in every livible location.

Good luck!
You'll need a test cd to generate various frequencies. The problem is unless you have an EQ you are only left with crossover frequency, volume, placement and probably phase.

How do the subs sound now? Why are you not satisfied?
