This mechanism will start to produce magnetism that sucks and pull push the paper backwards and forwards. The result is that we have very strong base coming from the Subu for Paper cone So if we want to have a huge and powerful subwoofer, we absolutely need to have a very expensive and huge magnet and very precise made paper cone Which are basically impossible to have to complexity and expensive cost We can use a huge motor higher torque has the higher RPMs can reach the higher is the power of our subwoofer So basically is a cheap way to sound just replacing and choosing the right motor Be careful, don’t exceed with the RPMs of the motor. Otherwise the centrifugal forces can make the whole project crash on itself. Seriously golf force will expand molecules of the parts, and at one point everything will crash outward Basically, the motor will speed always at the constant RPM, and the propeller always spin flat with no air proportion at all So the blades are just there and cut the air without moving the air at all when it’s not activated from a base If we change the page, so the angle of all the blades in one single moment, we can introduce a very strong air movement that is similar to the air movement of regular regular Subfer This happens very quickly, and will produce a change of pressure in the room, and we can clearly feel it with our body Of course you can make things if you make the propeller bigger or if you place in front of an open window with around around it This is important because the fan blower we just made have to create a change pressure between rooms And that’s the reason why we replace it in front of the window so that we can take the open space air and push it strongly inside the room Parts, using a 3-D printer and a CNC machine that machine full block of alum You can imagine that these weird shapes are very difficult to machine for this reason I decided to use 3-D print service online and I receive all the parts in four days
