Thunderbolt 1000 makeshift blower question

again, it puts out 750 cfm with no restriction on the outlet. What it manages to actually force through the siren head will be another matter entirely. It'll still make it louder like Eric said, but not as much as you might be expecting.

Yeah. I guess I meant that it will "fill out" the sound more than make it loud. That's more what I meant by "kick."

Yeah, all I wanted it to do is give it a deeper tone and make it a little louder
