The information that I am looking for is;

What is the paper drivers model? (I know It should be on sb acoustics)

Are the drivers 4 ohms or 8 ohms?

What is the Tweeter model? (probably sb acoustics too)

What is the amplifier being used? (3x150w)(looks similar to system audio silverback amp)

Link a supplier for the amplifier, please.

Is there bracing inside the A500 or is it like the S400 with no bracing?

If can help me out just a little bit that would be wonderful, thanks.
