Strictly gut but If it were me these would optional additional models that deliver a more robust low end out of a smaller box right out of the box.
Offloading bass to powered sub means smaller external amps can be used and usually means better performance and dynamics all around.
It's a very practical and cost effective approach that should appeal to many. I have F5 series 3 Ohms which are similar to 5015 with no built in sub and one generation older drivers. The 5015s must be the bomb I would think. The powered sub models are definitely something I would consider especially when the day comes to downsize.
