Step 3Shock mounting the speaker
Prepare the shock mounting system using the bungee cords, the crimp-on ring terminals, and the hose clamp.
Pick the right size crimp terminal rings: The crimp ends should be just large enough for the bungee cord to fit through, and the screws that hold the lugs onto the shell should fit through the rings.
The two bungee cords will eventually end up as 8 total pieces. Four will mount to the four mounting holes of the speaker. The other four will be mounted to the magnet using the hose clamp.
It is handy to make a reference template from one of the drum heads to position the speaker. Place the drum shell on top of the head. Mark four points on the head that line up with the mounting holes for the lugs. Remove the shell, and use a ruler to draw two lines through the center, connecting opposite marks in an "X". Center the speaker on the X and align the speaker's mounting holes with the lines. When it is centered, trace around the speaker. Keep this reference template head under the speaker and shell for the rest of this step (3). We will use this template again in step 5.
First cut the two bungee cords in half. By folding them, you can get the midpoint without measuring. Remove the hooks. Each piece should have a staple or crimp thing that was used to keep it from slipping through the hook. Slip each of the pieces through the mounting holes in the speaker. They should hold. If not, use a washer to make the hole smaller, or find some other way to attach them.
Next, remove the insulators from 12 of the crimp on terminals. This is safe, since we're not using them for electricity, just for their mechanical properties. Slide one crimp terminal over the end of each of the bungee cords. With the speaker centered in the drum shell, adjust the crimp rings so the ring ends just touch the shell without stretching the cord, and crimp them in place. You should have just under an inch of cord between the speaker and the crimp. Cut off the remaining bungee cord to use for the second set.
Crimp a ring onto each of the four pieces. Clamp the rings onto the edge of the speaker magnet using the hose clamp. Tighten the hose clamp until it is close, and slide the rings between the magnet and the clamp. Make sure that they are aligned with the speakers mounting holes, then tighten the hose clamp. (alternatively, you could just clamp the ends of the bungee under the hose clamp)
Slip the last four crimp rings onto the ends of the bungee cords. Adjust them the same as before, with the tip of the ring just touching the shell without stretching the cord. Crimp them in place and cut off any remaining cord blocking the holes of the rings.
Now is a good time to test the shock mounting system, so you can make any adjustments while there is still plenty of room inside the shell. Fit the lugs back onto the drum, attaching the shock mounting system with the same screws.
