I'm going to pick up the S&V and Stryke test disks for my sub and need a good meter to tweak my system. I'm I right that the Radio Shack meter is the one of choice for the money ($50.00)? Are there other suggestions? Does anyone know if the built in meter in the HK remote would work as a subtitute for the Radio Shack meter. The manual says I can use it to calibrate with a test disk, but has anyone ever done this with one?
