Here's a photo of my setup:

I did a direct comparison today between the Genelecs and the Beymas in the same room. The initial observation is that the Genelecs are outstanding given their size. And the placement with windows behind them isn't optimal. The Genelecs produced substantially more pronounced bass compared with the Beymas driven by the 4w+4w single ended tube amp. The Beymas do play louder than the Genelecs which clip before reaching the output levels of the Beymas at 4watts. The upper end of the Beymas seemed a bit more poppy and etched in a good way, whereas the Genelecs sounded slightly muffled in comparison -- possibly due to the more full range presentation of the Genelecs compared with the bass lacking nature of the Beymas. I give the mid and upper end detail to the Beymas. I have an NCore amplifier on order to see how it compares with the tube amp.
I'm planning to build a Linkwitz LX521 to test in conjunction with these speakers I already have. One plan is to create an open baffle housing for the Beymas and place them on top of the LX521 subwoofer section. The drivers in these subs measure very well though they are low sensitivity 86db compared to the Beyma's 98db. I couldn't find a 12" or 15" bass driver that measured better. However I am curious whether there is an advantage to using a larger high sensitivity driver compared to four (two per channel) low sensitivity drivers in the LX521 subs. Any suggestions are appreciated. In addition is there a better option than the 2x4 MiniDSP crossover or is this sufficient?
