I don't think it can hurt. The Sp-55 really blasts the sound out there. /ubbthreads/images/graemlins/smile.gif
I do have some open country in my parts and it can get windy, so the extra punch for me is great. /ubbthreads/images/graemlins/grinning-smiley-003.gif
You will really appreciate the sound level when you get a couple hundred yards out in front of your speaker and hit the remote.
We usually are sitting behind the caller and making judgements about the sound level, go stand in front of it and get an appreciation for what that unit will put out. /ubbthreads/images/graemlins/grin.gif
