10/16 port siren full blast. nearly maxing the microphone lol 

finally i wanted this since years

Insert Decot References here….very cool!

Someone needs to make a detailed tutorial on how to do this because I am interested in designing my own sirens after I scrape up enough money to afford a motor

I think 10/12/16 might sound cool.

You should try 8/10/12/16 port. That is my favorite quad tone port ratio setup. I'm gonna make that sometime too!!

Sentry 40v2t-58h 10/16 ports

My grinder is 10/12 port. Rotors are 129mm diameter. I didn't need any weights, i just put the rotors on each side, printed in 20 percent infill, and the winddown is really nice. It's insanely loud, and definitely maxes my mic. I've released the STL's on Thingiverse if anyone ever wants to print it

Sounds like a Decot.

Sounds like aca hurricane

I want that siren

High pitched hurricane because it isn't 10/16 it's 8/10

Sterling n5

Dude you gotta make a 9/12 port siren as well it will sound amazing

Sentry 40v2t 10/16 port version

Do 8/16 pls🙏🗿

Port combination idea, 10/15 port

Aca hurricane
