Hi All,
I have made a 3-way correction with minimum delay for streaming purposes, but... Measuring the summation of the Front Left & Front Right speakers, there is obviously something wrong with the summation in the 100-250Hz area.
So what is going on here..?! How can the summation get that bad..?
My measurements are made with REW, through JRiver with ASIO Line-In (I am using an extra sound card for REW to feed analog signals to the Line-In).
JRiver outputs 7.1 channels to the AL Convolver (8 input channels, 12 output channels).
3-way is setup as:
Tweeter >250Hz
Midbass 100-250Hz
Subwoofer <100Hz
Front Left, Front Right and the summation of the two.
Only the Midbass still with correction through the convolver (I turned off the other power amplifiers).
The summation is almost non-existing.
The raw response of the Midbass drivers, with no correction/filter.
Here the summation is definitely a lot better.
AL Speaker setup.
AL Channel Routing.
AL XO Configuration.
