If you've moved past DJ'ing the occasional wedding for a friend and are now professionally doing regular gigs, you may want to move to a more powerful and specialized DJ system. Instead of powered speakers, you may want to move to separate system of amplifiers and passive speakers. Having a rack mounted amp also can provide you with space for power conditioners, an equalizer, and other signal processors.
Best of all, it lets you get passive speakers built solely for the purpose of being a speaker. No on board amps, signal processors, multiple source connections, and all the weight those things add...just pure, unadulterated sound from your passive speaker.
These speakers are also be excellent for permanent installations in places like dance clubs and music venues...places where you might be a resident DJ or have regular gigs. The passive speaker offers weight advantages for installation and, because all the powered equipment is installed in an easily accessible rack, there's not much need to get up to the speaker once it's installed. If portablility isn't the leading influence on which speaker to buy, you owe it to yourself to look hard at our quality passive speakers.
