[QUOTE="CTGT2005, post: 7675810, member: 573747"] I cant for the life of me figure out whats contributing to the harshness of my install. I've taken measurements using a calibrated microphone and have set the tweeter level slightly below the average. Regardless of attenuation the speakers still sound way too edgy. After about 5 minutes I want to gouge my ears with a rusty railroad spike, even with the tweeter at -6. The speakers are Alpine Type R SPR-17s I listened to the speakers on a sound board and they were excellent, they even measured close to what I'm seeing in car. I just dont get it, the speakers measure flat enough that I wouldnt expect to hear any harshness, but thats not the case. It is +/-4db but its a car afterall and the harshness I'm hearing is somewhere in the 3-5K range and I cant seem to EQ it out using the limited adjustments on the headunit. The harshness is mose prevalent in complex musical passages, female vocals, or distortion in the recording. Also, at low volumes, all that I can hear is the tweeter, its like the woofer doesnt begin to output at an even level to the tweeter until the music is blasting. My thoughts feel free to touch on any of them. Any suggestions would be immensly helpful. 1. High order harmonic distortion from speakers causing the upper midrange glare 2. Distortion caused by the amplifier: Soundstream Stealth STL4.500 3. Headunit Alpine 9883 low quality output signal 4. Phase related issue with the tweeter [ATTACH=CONFIG]26531125[/ATTACH] [/QUOTE]
