[QUOTE="Peter Morris, post: 43147, member: 652"] Re: M1d array correction [SIZE=4][FONT=Calibri][COLOR=#000000]Hi Scott [/COLOR][/FONT][/SIZE][SIZE=4][FONT=Calibri][COLOR=#000000]Here is an acoustic measurement of a line array element showing the effects of a 9 dB shelving filter at about 4K5. [/COLOR][/FONT][/SIZE][SIZE=4][COLOR=#000000][FONT=Calibri][FONT=Calibri]-[/FONT] [/FONT][FONT=Calibri]The purple is the original "flat" measurement. [/FONT][/COLOR][/SIZE][SIZE=4][COLOR=#000000][FONT=Calibri][FONT=Calibri]-[/FONT] [/FONT][FONT=Calibri]The blue is the 9dB shelf – note there is about 45 degrees of phase shift at 4K. [/FONT][/COLOR][/SIZE][SIZE=4][COLOR=#000000][FONT=Calibri][FONT=Calibri]-[/FONT] [/FONT][FONT=Calibri]The green is a modified preset to correct for the phase difference so that it is within 10 degrees or less so everything will still sum nicely [/FONT][/COLOR][/SIZE]Peter [/QUOTE]
