I have no neighbors when I play outdoors only those driving near my home would hear it I am very considerate and those saying otherwise are just the types that kick kids off their lawns.
The magic of outdoor listening
I tend to keep one system I can pull outdoors when I am in the mood the freedom from room colorations is an amazing thing. Being outside listening to a great system playing wonderful music is magic. I have a bike race by my home and if the weather is nice many times I'm out jamming I have had large groups of cyclists stop 50 yards from my home to enjoy my music. Last year I has using a giant pair of RCA front horns with a full range in it this year going with a community leviathan system with radial. I pull out a tube amp when I jam outside. When I retire I plan on putting out a permanent outdoor horn system so it is ready to go when I am. Sitting still seated centered in a room all alone is enjoyable at times but also kind of tragic I am happy I have options. Maybe consider the outdoors as one of your listening spaces.
