A:AnswerRegrettably, RMS (root mean square or mean power) power handling which refers to how much continuous power the speakers for the LG XBOOM 700W 2.1ch Mini Shelf System with Built-in Subwoofer and Bluetooth®, Model # CM4550 can handle is not listed in any documentation for the system.

A:AnswerThe Alligator clips in the rear of the LG 700W 2.1ch Mini Shelf System with Built-in Subwoofer and Bluetooth® only allow for the 2 speakers that come with the unit. Adding additional speakers to it would overload the output amp and burn it out. It can not connect to bluetooth speakers as the Bluetooth on the unit is for receiving a signal and not sending a signal. ^CP
