Genelec make a wide range of pro-quality monitor products with good to great dispersion and level handling for near- to midfield applications. Doesn't mean they're perfect, of course - the very smallest ones in particular are too hissy and sensitive (you also can't take the bass on the 8010 seriously), and their limiters tend to be on the conservative side (Neumann usually wins the output level comparison). They also tend to have dispersion on the wider side, which is good for nearfield use in a well-treated studio environment and keeps things tonally well-behaved even in less ideal rooms, but you may not like the amount of room reverb at larger distances in living quarters.
A monitor, by definition, observes, checks, controls, warns or keeps a continuous record of something. An audio monitor, studio monitor or monitoring speaker is more than just a good-sounding loudspeaker. It is a device used in the process of recording, mixing or broadcasting audio in any...

Note how even in relatively well-treated rooms, they recommend breaking out the big guns past 3 m / 10' for diffuse sound to remain under control. (Home listeners may have more lenient standards than this, of course.) And those still cost a pretty penny, even if still not "high-end" fantasyland prices.
If you consult the SPL chart, you'll also find that the very smallest models are limited by peak output level more than diffuse sound (assuming that we want about 102 dB SPL peak), which reverses around the 5" class.
Yes, a pair of 8020s with a matching sub or two (of the studio variety with balanced I/O and a integrated crossover) would make quite a racket for sure, but is this really the right thing for hi-fi listening distances (2.5-3 or even 4 m more often than not)? Probably not entirely - you'd rather want 8351s or 8361s for that. 8331s with sub(s) should make for one hell of a "cost no object" desktop setup though!
