I need a reciever with 11" or less depth and so that has led me to these htib setups that have smaller receivers. I have already wired pyle in ceiling speakers into my house. They say they are about 3.8 to 4ohms. So my question.... Is there a problem using one these htib receivers with my own speakers. Im looking at either the panasonic sc bt200 or the samsung ht z320t. Also is there anywhere to purchase these type of dvd receivers without the speakers since i dont need them?
