Another question about blowers.

[coastalsyrolover]

So my question is: the 1000Ts loudest blower is the 5M. The 6M on 1000Ts aren't louder than the 5 but are still louder than the 4 despite being a bigger blower. However on the 1000s the 6M appears to be the loudest despite not having the most CFM (the 5M has the most and yet doesn't seem any louder than a 1000 with a 4M.) anyone have any ideas on why that might be?

I think the 5M is the loudest regardless. The 6M is just raspy.

The 6M is pretty potent. The Thunderbolt 1000 at the Randall County Annex is the only siren here that made me reconsider getting close. I've never heard a 5M in person, but i'm willing to bet honestly the difference is probably not that huge. You can only force so much air through a 3/4" by 3" hole that's closed or partially closed half the time due to the spinning rotor.

I just recall Ian saying the 5M on a single tone doesn't seem any louder than a 4M but the 6 did make it seem a bit louder... the 5M I've defiantly heard about being loudest on the 1000T. I almost suspect it's just the fact that it's a slower running blower? It's not shoveling the air in as hard maybe? Or maybe it's just the rasp that makes it SEEM louder? The only 6M I've heard is the one on my elementary school as a child and of course the one I heard the other day I suspect had a 4M (maybe someone from Nebraska can confirm it. VA hospital in Lincoln.) mine had a 5M but they scrapped that blower and I haven't had a chance to replace it yet... (I think it was fried too...) anyways so I'm not drifting or confusing people too much... I remember the 6M was earth shaking loud but of course so was the 4M... am I just crazy or? Facing me it was for sure louder than the SRNB and what I remember about the 130... you guys too?

Didn't we already have this conversation about 2-3 years ago?

Idk man. I know I've asked about it on 1000Ts and the 5M having more CFM. But on the 1000s the 4 and 5 hardly have a difference yet the 6 seems to be a bit louder (or maybe it's an audio illusion.) I don't believe I've ever asked the latter question before.

No matter how you put it, the 5M is and always will be the loudest blower on a stock Thunderbolt.
