Does the sub come with aluminum or copper coils? sorry if theres a thread about this but i looked on the site and couldnt find a difinitive answer on this.

Also what exactly does the BP power option do, does it effect the sound of the sub whatsoever or is it something just to help with thermal capabilities of the driver?

thanks in advance.

I believe it has aluminum coils. BP power is a plug machined from aluminum placed inside the pole vent to aid in cooling along with six axial cooling channels in the top plate and a changed spider pack. Raises thermal handling 200-500 watts, and beefs up mechanical ability some more aswell. Supposed to be close to origional thiele small specs.
