Most decent receivers will allow for "no" sub. You set the mains to "large". The unit will reroute all bass to the R/L speakers. The problem here is that bass is very taxing on an amp, especially a receiver. The speakers may be up to the task, however, your receiver probably won't have enough power to make you happy. Bass below 80hz sucks virtually all of the juice from an amp.
That's why a smaller sub may seem bad, when in reality it is a good thing to have a separate sub with its own amp. Same old story, it's not the size of the sub....quality vs quanity.
