I see. Makes sense.
Keep in mind that the trend will be for smaller "efficient" speakers to have limited bass response (that's how a lot of the efficiency happens, power requirements go up exponentially as frequency decreases).
If it becomes a problem, and it may not depending on expectations, then that's where adding subs and blending them in well solves the problem effectively, if done right (not always easy to do but usually doable in the end).
The key to good coherency is often to not have crossovers in the midrange frequencies where most music (and voice) occurs. Bass region crossover points as is the case with subwoofers is not problematic in that way, but getting levels right in the bass (reasonable flat one would expect) more so. Electronic crossovers and room correction software is probably the most fail safe way. Again, I believe that is what MartyKL does and often recommends (smart guy!).
FWIW, my little Triangle Titus monitors sounded top notch in my decent size family room/kitchen area prior to the sub I used with them finally dying. That with mere 70s/80s vintage 15-20 watt (SS) receivers. I've always had teh Triangles targeted for trying a mimimal power tube amp someday, but would not put them back in that room without a sub or two again. I'd bet your DeCapos would likely do at least as good or probably much better even on a SET amp with subs. Without the subs on a SET, it might be a closer contest.
