Working in a room and we discovered "reflex sound" works!

just like a gssip, my report. thank youy ! good morning. 
we were working in a bedroom for mprovement, while moving fornitures and preparing paint, we played music, using an old minicompo,
passing by front or staying there depending the position, very sounds were reflected in the wall, and so depending the position and Mid / High freq. we noticed a kind of 3D stereo sound, even when the speakers were in a random position just to listen while we work. 
time ago in car audio I saw the user manual for speakers installation, they suggested in some way take advantage of the windshield or angle of the window for the position of tweeters. maybe if we prepare other room for home office, we will consider the 5.1 and possible walls that reflect the sound.

Same effect using "upfiring" speakers and using the ceiling for added disbursement.  Sometimes it takes a bit of getting used to but excellent for bigger sound like classics, etc. but still need to do your homework for the bass - you can't beat a clean/even low bass sound!
