Hi, also got the 8030 and I am pretty happy with them - very detailed with great stereo image.
If you look at their freq graph they roll of quite steeply below 55 hz, so you´re right, they do lack bottom. However, my room is not very well treated so I find mixes done on the 8030´s much better sounding in the bass area than the bigger KRK´s, Adams and Tannoys I used before!
Why not take a sub into consideration if you want deeper bass? Isn´t Genelecs 7050 tailored to use with the 8030´s? Just a thought.
(No, I´m not affiliated with Genelec. But I´m going to Finland in march!
