Try removing the DXR15's from tripods if you want disconcerting ;)
Got to admit - I had my 15's out with me this weekend (complicated and long story but it appeared I may have been forced to park miles away after unloading....luckily that particular manager wasn't there on the day so it didn't happen ;) )
I'd forgotten how powerful and capable they were since I took to going out with the DSR12/DXR8 combo. Might have to give them an airing a little more often :)
