this made me laugh so hard!SirenMadness wrote: ↑Fri Sep 21, 2018 1:51 amThe neck and intake cone were not perfectly segregated from each other - the chopper just loosely took up space inside the housing - so I suppose blocking the neck would simply direct a portion of the sound that is reverberating inside the chamber to try and belch out the front bell. I'm sure B&N realized certain shortcomings of the housing design and worked around it by equipping the siren with a yelp mechanism for that very reason.
but yeah. you would either have to block the chopper directly or cut off its air intake.
