Hi Coolbreeze23, Are you sure R527 is 4.7 ohms? What I read is Yelllow - Violet - Black = 47 ohms. Can you recheck this? Thank you

Klipsch speakers are good designed but not the sub. Here is why: In order to have great sound without noise, Klipsch engineers have to use linear power supply. There are two kinds of power supplies: Switching and linear. The power supply of your computer is switching. Linear is different, even you turned it on and don't use it (no sound), it still consumes the same amount of power and extra power is generated to heat. The heatsink of the linear chips is small and not attached to the back metal pannel to disipate heat to outside. Trust me, even you have brand new speakers and without modification or adding cooling system to it, you will shorten the life of the sub (amplifier). One day you wake up and....: No sound from speeakers but headphone works fine, fuse blown, sound distortion, all kinds of problems... When you send the sub to Klipsch for repair (if you are lucky, still covered under warranty), the tech only replace the defective components, not changing the design, so the heat is still there....and soon or later the problems will appear again... There are three things you can prevent this: 1. Turn the volume real low, just enough to listen (a polite way: not to disturb your neigbor) 2. Add cooling devices to the sub (if you know how to do it, or hire someone to do it for you) 3. Put it on Ebay to sell BTW, ultra 5.1 is a great system if Klipsch fix heat problem. Good luck to all If you want to know more, email me: ptran3014@yahoo.com
