Onkyo AV Receiver HT-R538(Surround sound)(missing woofer) ?

Onkyo AV Receiver HT-R538(Surround sound)(missing woofer) Good receiver the only thing missing is the woofer hence the price as it was an expensive unit my cat decided to turn the woofer into a scratch board ! anyway you can pick up woofers pretty cheap you can still use it for surround sound and it does a good job of that ,and when you add a woofer it will give it a wee bit extra ,but as I said still does a good job with out the woofer ok cash only & pick up see pictures
