Curious about the siren/speaker(s) on the SS. Looking at pics of the Sabres, you can see what looks to be 2 project-a-flex speakers (the original side speakers with the hose between driver and cowl) in the space between the fog lights. The SS has a grill in the bumper, I imagine a speaker lurks behind but have never found a photo where I can clearly see. I have seen a pic ,however, of an M-plate Volvo ALP with a bigger hole in the bumper where you see 2 project-a-flex speakers behind. Not sure there is room for 2 behind the grill on the SS's bumper. The dirtier/scratchier tone of the siren of the SS certainly identifies it as a project-a-flex style of speaker. Given that the 2 clips, of Sabre and SS, were taken at the same time, same camera, same traffic conditions, i find it interesting that the SS siren definitely seems to sound louder than the Sabre's. Not sure whether this is due to video production or not. Turn the volume down and listen with a fan, or other background noise playing, you might hear the same thing. So....if the SS siren is at least as good as 2 100W project-a-flex speaker? Assuming they are both using 100W drivers. THere's no doubt the SS's siren is seriously loud, it must be as least as good as an SA40 lo-pro lightbar speaker, used widely on fire appliances for the last 10-20 years and more. Point of this comment is how amazing the horns sound, as in Andy's WM turnout vid from the same period. I get the impression that a lot of enthusiast KZfaqrs may have never heard roof mounted horns with their own ears. And have mostly heard the "box them in" fitment which makes them a joke on most modern appliances. I grew up hearing horns on Lancashire appliances (not roof mounted by then), then horns and sirens (horns used an awful lot, almost always with the siren), GM appliances with roof-mounted horns (effectively no two tones after the mid 90s, they were fitted but never used - I didn't hear a Volvo with two tones until 2008, must have seen/heard over a thousand responses by then) and Merseyside SSs, I saw dozens of those. Replace that SS by a modern merseyside (one of the few who still enables their appliances to use siren and horns together) engine in this video and the horns would sound like you have won them in a Christmas cracker, by comparison. Check out "soi buakhao london fire" it's the same loud clear sound you hear from any roof mounted horns. Not the muffled rubbish you get now. I was walking in Liverpool a couple of years ago, turned round upon hearing horns faintly, and was amazed to find the engine only about 30 metres away, this wasn't even in heavy traffic

All fire engines should just have two tone horns and bull horns. I love that combination.

Blimey didn't expect the old Dennis ss to be fitted with the bull horns

I like these old Dennis fire appliance's remind of my childhood in late 80s with the first dennis and 90s /00s with second dennis .and i also remember when west midlands fire service had orange colour fire engines they was in 80s .

Awesome!

Great video, stupid title.
