Eisenmann ESD with MSD?!

Halli Hello and a nice 3rd Advent 🙂 I would like to hang an iron man under my TT. Could you tell me if it is enough to screw the ESD underneath or if the MSD is absolutely necessary? I would like to have a sporty sound that won’t be annoying for a long time! – I am lying there with the Eisenmann “gold-richig”? ..or?! mfg from Berlin
