Does any DJ's use BOSE 901's for their system...?

..if so how do you hook up to the equalizer, amp, and mixer? And if you do use 901's you have them on tripods or hanging? And if hanging what kind of hardware did you use and how do you hang then at each gig? And if you use 901's how do they sound ? I have a pair that I don't use much in the house and I am seriously thinking of usuing them on gigs..
