My Focal Stella Utopias have no trouble energising my 'difficult' room.
They each use a 13.5 inch field coil bass driver, similar to the 18 inch one in the Grande Utopias. I'm a fan of drum and bass, a genre where the melody is in the sub-bass region, as wel, as root rockers and dub reggae, plus deep house. No other genres require more ,well-controlled, deep bass
My speakers are supported by four 18 inch Velodyne dd18+ subs, in stereo bass stacks alongside my main speakers. I reckon I've got sota bass.
