The RCA Rt2770 comes with 4 satellite speakers, a similar center, and a passive sub.

The overall volume is a little on the low side, which is mainly hampered by the smallish speakers and the passive sub - replacing any of these will allow the amp to push more volume, but some may prefer the smallish speakers as they are compact and easy to hide.

Fortunately, they are so small as to be barely noticable (visually).While the sound is warm and clear, the receiver seems to have a rather low maximum volume compared to other home theater systems, but I think that has more to do with the small size of the speaker cones limiting the amount of air they can move, and the fact that the receiver has to do double duty driving the passive sub
