SVP SA-450 Siren Test with Whelen Speaker

Bench testing a SVP SA450 Siren. The speaker used is a Federal Signal BP100. The resistor setup is to reduce the volume for testing purposes. It consists of four 900 ohm 3.75 watt resistors arranged so that there are two resistors in series, with the two pairs in parallel.

Is your resistor setup inline on the power or speaker wires ?
Great video !

[@ctbigcat]

The resistors are added inline to a speaker wire.
