How do you say quad drums in French?

I'm doing a project for my French cl about the drum line that i play on. I've already found out how to say cymbals, snare drum, tenor drum, and b drum in French. However, I can't find a translation for quad drums, or quads. Can you help me? Don't give me a website or tell me to look in a French dictionary please. If you don't know the word then don't bother answering.
