Before i start may i say welcome and what i am about to say is my opinion 8)
For what you want i would say the Zensor 5's would not sort you out in the low freq area at all. Although lovely looking speakers they are tiny and wouldnt give you the clout that your preferred music choice suggests you are after. The 2050is on the other hand judging by the reviews are big, loud dynamic floorstanders and i would say out of the two thats definitely what i would choose. This is my opinion and im definitely not an audiophile, just a dude that loves music. Audition both though as you may prefer the Zensors.
