loved my Mackie equipment until I had to deal with a customer service issue, worst experience I have ever had. I have been DJing since 1987 and I have never had so many issues, the service center sent me beat up cabinet nothing close to what I sent in. two months for the repair, thier response is all they can do is chastise the service center but nothing else. I sent them a prestine sub that sits in a country club banquet hall and this p.o.s. they sent back is beat and scratched. the serial numbers don't even match what I sent them. never again.
