In Japan, only 5-1/2" black of REMO DynamO can be obtained. I put the BDM-F bass drum muffler full size and DW-1 weight of Pearl Drums in the kick and I put in AKG D112. Set the U47FET and U87Ai in the head of the part not hole cut. So I cut a 20" kick like the 7" DynamO with a diameter 7-1/3" hole cut. 22" is the volume of the kick, the hole cut by the area ratio of the head and hole cut. π(20/2)^2·14":π(22/2)^2·14" Radius ratio 1:1.1 Area, volume ratio 1:1.1^2=1:1.21 So I cut a 22" kick with a diameter of 8.1" against 7-1/3" of 20". In Japan there is a distributor named OLFA and a cutter knife maker of the manufacturer named NT. I cut holes with OLFA compasses cutter, dividers. #パール楽器 #pearldrums #sabian
