Electronic music may be very demanding at the 3rd octave, so i suggest that the speakers should be able to reach high enough spl's over there, and maintain some headroom for equalization.
If you desire strictly a 2-channel approach, maybe these krk should be considered:

The matching krk sub (10") is quite capable and not highly priced, which means you can get 2 subs and have money for even more...
Another suggestion is the Presonus Sceptre S8:

Which seems to have a very capable 8" woofer for plenty of punch. Also they are coaxial's.
Anyway,
I would strongly recommend a multichannel setup, at least a 5.1 one with a nad processor (at 1.3k with dirac). In this case, smaller speakers would be more convenient in a small room, and maybe 5pcs of Neumann 120 would be the best choice:

Paired with the Neumann sub.
