[QUOTE="_Dejan_, post: 6299829, member: 588417"] Today Im try mesaure my system with TrueRTA and get next results: First mesaure noise in car: [IMG]http://www.bukowc.com/Galerija/Avtomobilizem/Stilo/CARPC4/RTA1/NoiseFloor.JPG[/IMG] Im not shure if dB is ok I think it must be cca. 10-20dB lower... Then Im mesaure Left MID (Full Range): [IMG]http://www.bukowc.com/Galerija/Avtomobilizem/Stilo/CARPC4/RTA1/MIDLeft.JPG[/IMG] And Right: [IMG]http://www.bukowc.com/Galerija/Avtomobilizem/Stilo/CARPC4/RTA1/MIDRight.JPG[/IMG] Tweeter(BugPass filter at 1.5kHz you can see slope)... Left: [IMG]http://www.bukowc.com/Galerija/Avtomobilizem/Stilo/CARPC4/RTA1/HIGHLeft.JPG[/IMG] Right: [IMG]http://www.bukowc.com/Galerija/Avtomobilizem/Stilo/CARPC4/RTA1/HIGHRight.JPG[/IMG] For first mesaure I think that results are ok, but I must check why sound go +/- 5dB... In generator Im use "Pink Noise" and leave it 10sec. to make average. I think that with "Quick Sweep" has been signal more linear... [/QUOTE]
