I have a 50w head/cab in the bonus room above garage. I don't usually play very loud - but that's a relative term, so I've never had neighbors complain. I can play it quite quiet at night if needed, it loses a bit of warmth at lower volume like any amp would, but I consider it very reasonable. If I were in an apartment/condo that may be a different story but I don't think I couldn't keep it low enough to still be usable. I have a 40W Fender Deluxe that I have much much more trouble keeping under control. It just can't really get that quiet with standard volume pot, and it's drive/more drive setting is completely unusable anywhere as closed in as a bedroom/bonus room.
