I did not dj utilisCe but I like most dj ... so that problem meeting with former MODEL: cracking the sub depending on the Bo0um, bo0um, membrane that dchire etc ... FINALLY GONE! And silent time! then this box has a high pressure level of bass that goes down well in the infra ... In short, this box provides a sound comparable to much more expensive boxes! parcontre what I like least biensur the weight and the fact that Mackie has a half time before acting to remove all the old problem of meeting version! So here...!
