Best blaster speakers help

[AndersG]

Hey guys! I am in the process of making the final version of my "functioning" blaster. I'll make sure to upload pictures/videos once complete but i am stuck on finding the best/loudest small speaker to use.

The blaster is quite loud when fired (compressed air) and I am trying to find a speaker small enough to conceal but loud enough to be heard over the sound of the prop actually firing. The sound level is somewhat similar to a paintball marker, if not a bit louder. Any ideas?

Attached are some stills of an earlier version firing, I'm quite proud of how realistic the self contained "bolt" and impact look

Are you the one I was hearing about all weekend at the con? You’re popping balloons with the laser?

ha, not me! This one shoots an actual projectile. Sounds cool though!
