Changing the crossover frequency probably won't helping this case. Your problem area seems to be in A lower octave that your tweeters. Try EQ'ing the problem area. T/A can effect phase, but you may need to use a lot more to effect the issue you have. Try using you r EQ first and go from there.

Mids up in the dash is becoming more popular because people want a high stage height and gear that kick panel mounting will lower the stage. It also make the speakers harder to block by feet.
My tweeters can play 800Hz! But this would cause more problems than it would solve. You should also note that some of the best sounding cars are using wide bandwidth speakers. These speakers allow the user to use the mids for the entire vocal range (in my case 100Hz to 12Khz) Creating a more seamless and easy to control sound.

This is a key factor to a great sounding car. By removing crossovers in the vocal range range, you also remove the possibility of phase shifts in the vocal range.

 

alright i changed the xover on the mid from 120 to 10k and i lost alot of life to the music... so i then changed the tweeter from 1.2k to 20k and lost alot of impact.. hummm ok lets put the xover point at 5k this seems ok. but still problem in this narration.. so lets take the speakers out and check phase, well everything is in phase so i put one tweeter out of phase and bingo!!!! cleaned it right up.... now i will just play a bit more with the xover points and slopes and should be ready for penticton... oh ya i also changed the 4 inches from a second order box to a 1st order.. much nicer as they have a high q value, small sealed enclosures were sufficating them... now they really sing.. also my whole interior is at custom creations getting the golden touch by derik... hopefully it will be done by 22..

 

Did you adjust the T/A up one or down one? Had a similar problem. Mind you my TA was maxed out on the P01 to delay fronts so the sub would catch up. Now there's a secret!!! :P

 

interesting i will talk to mark eldridge tonight about that...hummmmmmmm.

 

10 4 - us know what he says.

 

If you used all the TA in your deck you did something wrong. That or your deck dosent give you much adjustability.

Adding small amounts of TA on high frequencies won't do anything. Your ears are more sensitive to intensity in those frequency ranges.

Most mids won't play properly above 5Khz, so crossing your mid beyond that is pointless. Not sure what your install looks like, but the further of axis you go, the poorer your off axis response will get.

TA should be in the back of your mind if your just starting to set your car up. It very easy to get a center image. But it's very hard to get a good center image. And you can ruin the rest of your stage buy thinking that because you have a center image, means everything else is ok.

 

I think this may be the biggest challenge with the new install and dash work. You are hugely off axis, and are dealing with a mechanical time delay and reflection issue of the windshield. Add to that, you are not identically off axis due to the angle variations i notice in the build pics of the dash. The difference being that the drivers side seemed to be a bit more off axis and also had to work against the hump over the gauge cluster.

 

the deck corrected for most of the speaker placement issues... the phasing was the problem but has since been fixed. the car now sound incredible at all levels and with a wide variety of music... as with anything nothing is for free. so for me to bang on centre imaging.... i loose some stage depth...... to get fantastic stage depth i loose focus, ect ect.. so its what sounds best for the iasca c.d. then after the judging i change the settings and put on some good demo tunes from chesky records or clair marlo to really show off how this thing sounds... i find that when i listened to kick panel cars they tended to sound about bottom dash hight but staged ok... then kicks with waveguides, that was increadible.. then the same setup with a pillar tweets was by far the best i have heard.. of course all eq/xover/ta proper. this is my first dash rebuild with wideband mids and have found alot of new challenges.. wow.. kicks were so much easier!!!!!!!! anyway hope to get some good feedback at the penticton show on the 22... any advice is always welcome
