I was looking at their facebook page and seen what appears to be one in Macon. Has anyone seen or heard these things in person? They claim they put out 136 Db, but the setup looks the same as their other ones.

The 136dB spec is probably a calculated value based on the measured 1W/1m specification for the horn/driver combo (the efficiency spec most common in the audio industry). The distance would thus be 1 meter from the horn.
