Hi, My Promedia 4.1 is not working properly recently. After I plugged the preamp in and press the ON button, the subwoofer make a rumbling noise even when I didn't plug the input into my computer and also when I plugged into my computer. Inaddition, regardless of what speaker/sat. I use, when I connect it to the Right Front connection, the Right Front speaker will produce static/crackling noise ( I even use a different wire etc...). If I turn the volume and SW knob all the way up, the static and rumbling improved a little but still noticable. Anyone know what is the cause and what part I need to replace or repair? Thank you. edit: Now static come from all sat. speakers

Hi, Where do you get Klipsch 4.1 for 223.99? I love to know because 5.1 is out of my pocket book. I just wasted $ on a new box. Thanks KL
