I actually did the mid/mdbass gain with a 1Khz -5db tone and adjusted the gain with my DMM/Oscope. It tells me the output voltage while it is showing the sine wave... 17.6v no clipping. 77.44w with a -5db tone. I brought the tweeters up by ear, brought the sub up both ways DMM/Oscope and then by ear. It's gonna chill till Wednesday, my next day off... then it's pink noise and EQ for a couple hours. I did the time alignment and it seems wide though my left side is still noticeably low in the door compared to the right channel which sounds head level. Not sure how to deal with that.Do not set amplifier output gains with sine waves. Especially with the speakers connected. Set midbass or sub output with sine wave and dmm/scope, then use the rta to match output of every other speaker to it.
I liked my tweeters better in the A-Pillars but whatta ya gonna do. They are in the stock upper door locations now. Midrange and midbass are the same speakers. I have a sunroof with a cover... when the cover is closed the treble is less harsh, cover open and the treble gets harsh. Main rattles I can here are left sun visor and the center forward sunroof area when bass hits. Doors are pretty quiet.height is going to mostly come down to two things.. phase, and rattles/resonance.
If you have any rattles and resonance, it'll never alleviate the issue. Your ears will always be drawn to it. Phase (no, not polarity. phase) is the second one. If your midbass is out of phase with your midrange, and/or midrange is out of phase with your tweeter, they will never act as "one". When they are all perfectly in acoustic phase, the highest frequency driver will usually dictate stage boundaries
side note, I'm doubting you have any form of good imaging right now if you didn't do any eq and your stage hight is pulling down. Good news to that is, there is a LOT of improvement that can be made in your current system
Yes, crossovers effect phaseTweeters face each others in the doors and are about 12" above the mids, which also face each other. Mids upper Xover is 4k @ 24db and so is the tweeter 4k @ 24db. If I remember reading some of the links you sent me, crossovers have a lot to do with phase? It rained today so no EQ settings... no rain forecast for tomorrow.
I just read this: Let me ask you this. If I play a 4Khz tone in the car and the left side sounds lower in the door than the right side... do I then adjust the tweeter delay in the left door to move the sound to be in phase with the mid and tweeter therefore moving the image higher?
In part two, we discussed comb filtering and how it affects both frequency response and imaging. Comb filtering is caused when two sources of the same...www.audiofrog.com
Yeah... Had the sub - Silverflutes as midbass on their own rear channels of the 4 channel amp - then had DD 2.75" mids and various brands of tweeters off the front channels of the 4 channel amp... which is why I was also running a 2-way passive crossover to the mids and tweeters since I didn't have dedicated amplifier power for the tweeters. I crossed over the the signal INTO the passive crossover and let it's internal components split the signal to the mids and highs. 65hz sub - 80 to 350hz midbass - 350hz and up into the 2-way passive crossovers. 4 Channel amp, 6 speakers.Yes, crossovers effect phase
Do NOT play a 4khz sine wave. Do not play ANY sine wave with your speakers attached/unmuted. TBH, im not really going to get into this since you are still learning the basics. To much info at once is going to just frustrate you. At this point, just try playing pink noise with left mid and left tweeter playing and flip polarity on the tweeter or mid. pay attention to certain frequencies appearing/disappearing. You want the least cancellation as possible. You can do this for sub to midbass as well. Make sure you don't lose yourself and start adjusting phase of speakers on the side without confirming that your not ending up with each midbass or each tweeter out of phase from each other. Thatll cause even worse problems than what you have now.
Also, did you have a 3 way setup before? what happened to that? why are you purposely spending time to downgrade your system?
