KPO Pointers - Powered Subs are very popular solutions for professional DJs and working bands. They provide a simple solution for giving a gig great sound, Modern music is bass heavy and usually requires a sub. Most people do not want to deal with separate, heavy racks of power amps, crossovers and all the wiring associated with that. Powered subs themselves can get to be heavy so consider weight and size. Sometimes two smaller subs will give you increased portability and coupling two subs (putting them next to each other) will increase the volume drastically and lower the subs bass frequency capability significantly. Placement is extremely important with subs so if you are not experienced you may want to talk to our experts before deciding what to buy.
