Radio Shack Analog Sound Pressure Level Meter HTS800
This is the Radio Shack SPL (Sound pressure level meter. This is something that I could not live without. It is used in conjunction with a home theater setup/calibration disc such as Avia:Guide to Home Theater. This allows you to sit in you sweet spot for viewing and measure test tones from all speakers to balance them for optimal sound. Great product. And I do prefer the analog meter othe the digital.
