Hi, I'll like to know where can I get this system?

Hi there! Based on the results from my PriceCheck search, the LG LHD687 4.2 Channel Home Theater System with Bluetooth, HDMI, and USB looks like a great option for you. It has similar connectivity to the LG system you asked about, with Bluetooth to stream music wirelessly and HDMI and USB ports. It provides powerful 1250W sound and has gotten great reviews from customers. Currently it is available for R6449 from Takealot, so it comes in well under the best price I found for the LG system you originally asked about. Let me know if you have any other questions!
