When I was listening to them after I finished putting them together, they really sounded great, even pushing them fairly hard, easily beyond where the smaller 2.0s would struggle without a 125Hz high-pass filter.
When we put them in Danny's system, we did have an in-line filter taking off the bottom octave, since his room is a lot bigger, where the bass would easily get swallowed up, allowing the subs to take over and We were able to push them quite hard without ever really making them struggle, even on dynamic drum tracks.
They may struggle a little with dynamics down low as mains in a HT setup, especially without subs, but we are working on a tower version using 4 woofers down low to allow for better bass control and dynamics as L&R mains, and we are also just about finished with the network center channel-version as well.
If you set the speakers to "small" on your receiver and use a sub to take over the bottom end, you may be just fine with regards to dynamics.
