Once I lent a pair of these from a friend for a mixing job. I was very skeptical when I unpacked them and could hardly take them serious regarding their size. They are so small you can call them "portable" but they are also damn heavy for their size... When I first listened to them I instantly fell in love - easy as that! I just came back from mixing at a guys place with KRK monitors (don't remember which models) and the genelecs sounded way more sophisticated and natural. It's just another league. Much more of a working tool than a compromise! I didn't want to let them go and decided to buy a pair for my home studio setup. As they lack some deep frequencies I decided to get a subwoofer and ordered the 5040A that is big enough for my mixing room (25sqm). This is a beautiful little setup and I think the 5040A fits perfectly with the 8020s (even if this sub is usually advertised in combination with the even smaller 6010s). Genelec states that the 5040 was designed for both models and I can say it works and sounds great. You have to put the monitor volume at 12 o'clock and control the overall volume via the funky remote control of the subwoofer. The connectors of the bigger brother 7050 are more professional but for a small studio the chinch connectors of the 5040 are ok. The only real bad thing is that it's not possible to sync the two volume controls of the monitors, which means there is always the chance that one side is louder than the other one... I rate this speaker combination a 8/10 cause it really makes me happy.
