I have to say I've never seen 4 10's stacked vertically like that --- and with another cab on top to boot. Your bass tone must literally shake you from head to toe.
I dont actually it's either 1 or 2 cabs but I had them all at home this time so I thought to stack em
The top Hevos cab is very nice though (1X10" 400W@8Ohm + tweeter) Better than the Markbasscabs IMHO
but Markbass rules anywayz
