I think 2 factors will affect things with floor ported speakers. My only experience of floor porting is with my sub, a REL, which comes with spikes which screw into the feet of the sub for optional use. I seem to recall the manual saying that the spikes isolate the sub from a hard floor surface but they also raise the height of the sub and I wonder whether what they actually do is to compensate for the lack of damping due to the absence of a carpet/rug when used on hard floors. I actually use the sub on a ceramic tiled floor with no rug or spikes so I'm not certain that they're necessary for that purpose with the REL but if you're playing around with cones and other alternatives, be aware that the height of the port above the floor may have an effect.
I also don't know how prone your suspended floor is to vibrate but I would expect the port to help transfer energy to the floor at low frequencies and cones will do that also. You may end up inducing enough vibration into the floor to colour the sound if the floor ends up acting as a sounding board. In that case I would consider an alternative to cones or spikes.
Otherwise I'd tend to go with cones or spikes. A rug under the speakers may also help.
