Sound imaging and time alignment
Guys, I'd be interested to see what sort of numbers you've got in for imaging and time alignment. I have the 80prs installed in mine and have ran the autoeq and autotime alignment which has given me the following numbers. I have ran this a few times and each time it gives me different results. So far, I'm pretty happy with the following:-
Front right = 193.75 Front left = 67.50 Rear right = 212.50 Rear left = 267.50 Sub R and L = 135.00 I may need to tweak it a little bit, but so far when I listen to it, it does sound as though the voice is coming from the front of the car just above my steering wheel, which is about where I want it. The front components are high passed at 125 and are set at 0db. The underseats are low passed at 80hz and are at -10db as they are running in 2ohm mono. I don't want them overpowering the fronts too much. The rears are at -6db and are just for fill. I might get rid of the rears completely and go fully active. |
