My 1-car garage is 8'hx20'Lx10W and is made of brick with Sheetrock Roof and wooden 3-part Door that slides up to open, there is space between the door when it's closed and the wall of the Garage. My predicament is that I live in a very quiet neighborhood and I hang out on Saturdays inside the garage, in the beginning I had 2 old style [1970s] Pioneer 15" 4-way Speakers but was told by my neighbors that the "Bass" sounded very loud so I got rid of them and used just one 12" 3-way speaker and still was told the same thing, I believe that the Garage acts as a speaker enclosure itself which would explain why the Bass sounds so loud "outside" of the Garage, in other words, I have much more bass outside than inside. A friend of mine then suggested that I try to copy the situation of an Automobile, this seemed to make sense because when you are in a car that uses 6x9 speakers, it sounds loud but when you come outside and close the door you hear very little or nothing so I went and purchased four 6x9 Pioneer speakers and a 4-ohm receiver, I placed the speakers in the "ceiling" of the Garage about 5' apart and when the music is playing at low volume with the Garage door closed, you hardly hear anything outside but you have to pump the volume to get any kind of decent "Bass" and when the volume goes up then you hear the music outside so this almost worked as when you go directly under any of the speakers, you get the full blast and when you walk away from it, the noise lessens considerably but not enough for my neighbors. I went with a friend to Circuit City and there was a demo of a surround sound or Home Theatre set, I don't know which, it had 4 very small speakers hanging overhead on poles and a sub on the ground, we were both totally amazed at the sound you get when you step in between those 4 small speakers area, the set cost $3,000 though. Anyway, what totally freaked me out was that when you step out of the circle of speakers you hardly hear anything and this was in the middle of the store and not in an enclosed room so I am wondering if this is what I need? A surround sound or Home theatre system so when I go outside of the Garage I will not hear much? Will welcome ANY idea/advice please that will help me listen to my music with some Punch and still be friends with my neighbors, thanks.
