My reciever is a RX-V3000. Dont get caught up on model and brand. This is a common feature within your price range.
If you set your mains to "small" in the reciever you will get base from your subwoofer in 2ch listening. The frequency at which this base is sent to your subwoofer depends on the reciever you buy. Some recievers will allow you to adjust this frequency to better match your main speakers.
If you have large full range speakers and plan to run them full range or "large" in your reciever, you will need to make sure the reciever you buy allows a "both" setting so low base is sent to your mains and subwoofer at the same time. In this case you would need to adjust the high pass crossover on your subwoofer so you get no frequency overlap between it and the mains. You wouldnt want a subwoofer playing from 80hz down if your speakers have a flat frequency response down to 60hz. You would have an unavoidable output peak between 60hz and 80hz.
Hope this helps.
