I though I would just have a post for the subs I am building.

Single 1 ohm 3" Coil 3.25" wind width (18 awg copper wire)
Shorted this on a 1000 amp battery and takes it like a champ. Do some Big dummy math and it's actually over 10k... I told some kids I took the coil out of there moms vibrator after I banged her. The one ☝ the one lower ones the Gonzo Jizz facer jr. Spooged edition that's close to the ☝ there. Just has a 4 layer 20awg copper coil that's extreme and way better than that aluminum shit they use to save money bc copper electrically more efficient and don't brake when it gets loose butthole and slaps the side 3 times and no longer have 2 coils lol. Dumb shit people believe but cannot except this as truth. It is

What would be your cost savings per unit having your coils wound in aluminum instead of copper? Can you quantify the efficiency (or dB) gains you get with copper over aluminum coils in each of your motors? Are there any other differences in TS parameters you consider when deciding on which material you want for your coils?
