Actually it's just the opposite, the motor is only rated for ~1745rpm. The smaller 4M blowers are the ones that really scream, since they're pullied up to spin at somewhere around 2750rpm from a 1745rpm motor.SirenMadness wrote:A 1:1 pulley, that blower's gotta scream!
Not quite that loud, but I wouldn't be surprised to see it pushing around 130-131dB at a hundred feet out.DJ2226 wrote:This is going to be a LOUD siren. Let me guess... pushing 135dB @ 100Ft?
If it's hilly country it'll do well too because of that! After all that's what the Thunderbolt is all about; that attack cycle and the low frequencies being pushed out the way they are. It's not that it's that loud at long ranges but it has that reach because that 1000 up and down cycle really is an attention getter.It's going to be on a 55 foot pole also, so it should have a pretty good range. The fact that Upson county runs attack for tornado warnings and tests makes it even better. A 1000 is a bass monster when it hits the lower frequencies.
