BooYu 200W Compact High-Performance PA Siren Horn Speaker [Ultra Slim] [8 Ohms] [125-135 dB] [IP66 Waterproof] [Capable with Any 100-200 Watt Siren] for Police Car, Ambulance, Fire, Engineer Vehicles

Sounds very good, and great size. I had to buy to replace the bigger horn from the PA system I bought, but that was only because I didn't check the clearance I had before buy the PA system. Decent price and haven't had any issues with it.

Very loud

Very loud. This is a 200 watt speaker, I have a 100 watt siren, loses some sound on one siren tone but that's my own fault.

💯

I bought it "used" from Amazon to save a couple bucks. It was all beat up and scratched up. It was insure a plastic bag in its box. When I removed it from the bag it was very wet. Disgusting! I tried it anyway and it didn't work at all.

This is great speaker for attaching to my siren and air horn controller. I had to come up with a creating mounting solution but it works awesome!Don’t forget - you will need a site to or air horn controller.

I like the slim size and ease of mounting. I use it for my siren and PA system in my truck. I am NOT a firefighter or police officer. I have the siren installed due to a prior accident in which the driver who backed into me didn't hear me honking my vehicles horn resulting in my truck being totaled.

Well packed and nice solid material
