Here's an unusual request for ya. I need a Subwoofer. For under $20.
Basically, I'm building an Air Cannon. My plan is to use the subwoofer to create the necessary force. Thsoe of you who know what a Vortex Ring Generator (What it's called?) is probably know what I'm talking about. All I want to do is to hook it to a 9-volt batter and everytime I hit a switch, have it displace large volumes of air.
So...It needs to be big. 12" is good, 15" is better. I don't care at all about quality, since it isn't going to be used for sound. I do want it to be airtight, because the cannon is supposed to be airtight except for the hole the air is forced through. The more air it can displace (bigger sdurace area of the speaker I guess), the better. Oh, and did I mention I'm on a budget?
I put this in the Community, since it's a strange request and I don't know if it's appropriate for the Multimedia and Audio forum...since what I have planned involves neither multimedia nor audio.
