Open Baffle Convert

I recently took my 12" audio nirvana full range drivers out of their cabinets and into open baffles with wings. I can't believe the diference in sound. So much more 3 dimensional and lifelike. I was concerned the bass would roll off but I dont find it a aproblem at all. Munting them 14 inches to center of driver off of the floor seems to be enough. I am curious how many of you have heard this design. All of the downsides I had read about never materialized. Any thoughts?
