Thanks for the advice, i only have 2 front speakers and a subwoofer and wanted the microphone for setting distances so the speakers and woofer would be in phase. But did it manualy, put distance to 0.00m for every speaker and then started to change subwoofer distance and finaly got them to play at unison. Pretty easy with the nuprime because you hear the change for every 0.01 distance right away. Now i can enjoy strong clear sound without booming bass.
Thanks again!
