Getting bass down low with honest power is not easy. You have to deal with the laws of physics. A rough guess would be that 90% of speakers claiming bass to 30hz are putting out too little to seem realistic imo. You need to be able to move alot of air and drivers that can handle it. Without a sub you're looking at speakers with large cabinets.
There's plenty out there but don't believe the advertising claims of most speaker manufacturers because like I said most speakers I've heard claiming bass to 30hz and lower simply have no power down low to speak of. I actually run a sub with speakers that have power into the twenties and run them full range with a sub. The sub is crossed over at 45hz and it amazes me how much that sub is working. I will feel the passive radiator to see how much it's working and it's quite significant. I listen mostly to jazz and pop and that woofer has a pretty fair amount of work to do. Get as much bass power as you can if you want real bass.
The other downside to bass is you will have to deal with large cabinets as no mini monitors can do it, period. If your friend can afford the space and money then find some speakers that claim a minimum of 30hz or you'll end up needing a sub.
The room gain the above poster speaks of will vary depending on the dimensions of the room and the proximity of the speakers to the walls. This room gain is almost always added to manufacturers frequency response claims and is therefore little more than useless if you're looking for an accurate and consistent reference.
