Could it be that Sireno has the widening ports to avoid infringing on Federal Signal's design? Just a guess... That is the first time I ever saw such a design.
I don't think I've ever seen one of these babies in service out here on the Right Coast-- but then again we don't see B&Ms out here either. Too bad!
I always enjoy your videos.

I don't know about any infringement by Sireno, since this siren (originally called the ED series before ITT bought out Sireno) is slightly larger than a Q, and will out roll it! We had the chromed version, the ED10, roof-mounted on an ambulance. The siren was very loud and would outroll anything I've seen except on old B&M S8B Siro-Drift that I saw coast for more than 10 minutes one time! This big Sireno was so well-balanced that when we were sitting still at a local MotoX race one time, and had the ambulance slightly backedup the downside of an unused jump, the brisk southerly breeze caught the siren by "surprise" and it started rolling all on its own. Federal Qs and all three B&Ms will "wind coast" with the vehicle in motion...especially if the button has been slightly bumped; but this Sireno had a "mind" of its own!
