Just the HOR in Hamilton I recorded last Wednesday.
This is the last active single headed rotating Si-Rex in the US and in the world, and this one’s also dual toned in HOR’s standard 7/10 Port ratio. Was pretty loud and ran a full alert. You could definitely feel the sound in your chest throughout the test. Definitely covers most if not all of downtown Hamilton without a doubt.
