Measuring DB output
Posted: Thu Dec 29, 2016 8:16 am
I've installed the Gethru XA600 siren amplifier. The unit has two 200W channels.

The manufacturer indicates 120db output. He measured the db output with two 100w speakers.
I've installed only one quality 200w speaker and measured the db output using this app:
https://play.google.com/store/apps/deta ... dmeter.app
I had no choice but to install the speaker behind the front bumper facing down.
I've measured 92db less than 1 meter from the speaker.
I'd appreciate if you could help be sort out a few things::
1. Is there a better way to measure the db output with no professional expensive equipment?
2. Is it possible that I need two speakers to output the whole 120db?
3. How bad is to install the speaker facing down and not forward?
