Hello AOS family,

Yesterday I picked up some Kef C200 subwoofers. These are stereo and are made to be used with the Kef C15 and C25's. After checking them over I had a read through the installation instructions and according to them the subs need to be connected to the bookshelf speakers and should not be used without them unless you have a " 8 Ohm resistor of at least 50 watts in place of the bookshelfs"...

I'm thinking of using a 100watt resistor but have no idea of how it'll be used
So my question is how would I do this..., Do I just connect the resistor in place of the bookshelfs using the pos (+) and neg (-) connections?

Also where could I buy half decent resistors? Don't want to buy off the bay only to have them blow and damage the x-over.
