Love this duo

[@SilverThunder710]

What’s the difference between the R3 and R4?

[@JASirens]

The R number tells you how many speaker drivers are in the siren. So R3 means the siren has 3 speaker drivers while R4 means it has 4.

[@SilverThunder710]

@@JASirens Ok, that clears it up. Thanks

[@JamesSpeed65]

That Siren has 4 Drivers. So it’s an R4.

[@JASirens]

@@JamesSpeed65 this siren is a R3 as said by angleton, TX themselves

[@SilverThunder710]

@@JamesSpeed65 how can I tell if there are three or four?

[@JamesSpeed65]

That’s an R4.

[@TheSirenSeeker]

They’re R3s. We have proof from the city. There is no visual difference
