I be look at this product in store , and if you do not know you can stick a speaker cable in the intenna slot to use it as a intenna . when i be check it out . . i also notice nothing come out of the rear speaker ... then i notice that you can adjust the & amp ; quot ; distance & amp ; quot ; you be from the speaker . . this allow the system to adjust the volume accordingly . . so if the front be 5 foot away and the back be 10 foot away , but the center and sub be 2 foot away , you will still hear SURROUND ... its really cool , and i can not wait to buy they . . I have just over 200 and i need the differance . . I do not live in a apartment , and im not some punk ruch kid , but i do have to save my allowance to buy anything ... and i can not wait to play battlefield and hear the Airplanes fly overhead and im shooting the flak with the pouning shell from the subwoofer
