I'm a fan of draping curtains to cover hard items in the front, speakers and racks, and it does help, so I imagine that removing them altogether helps even more.
Also, just in general, the floor behind and between the speakers is too often overlooked. First reflection points are important, but the space here can affect treble harshness and ability to play loudly without sounding congested.
