Default door midrange issue

I will start this question by stating that I am running a set of $60 silver flute mids so maybe I am just expecting too much out of them? I am open to new mids, however, would like to correct install first so not running into same issue with better speakers

That being said here is my issue(s)
Car is 2004 Tahoe
mids are the 6.5" silver flutes
tweeters are the Seas silk domes
amps are 2 image dynamics q700.2 and I have 175 watts on tap to each speaker

1.My left mid is significantly quieter than my right mid. I assume this is due to off axis? If I open both of my front doors and walk behind vehicle they do seem to be the same volume so don't think its a bad speaker or wiring issue.
Do you think going more on axis would solve this issue?
2. Anything above 2k I get beaming. A friend of mine said this could be due to diffraction and having part of the mids blocked in the door. Its really just the frame of the speaker being blocked so not sure that would be an issue but I'm sure stranger things have happened.
-he also said with how it is currently installed it could be using my door panel as a horn as well.
-somewhat of a solution I have come up with is to trim the inner part of the door a bit so nothing is blocking the speaker at all. This would also allow me to go more on axis as well. However, wouldn't that in theory make the beaming more of an issue?

Here is a picture of a Tahoe door(not mine) but it gives you the idea.


also yes my doors are heavily deadened and sealed before that question is asked. I also continue to try playing with speaker levels and t/a on deck but it just continues to get more wonky

Thanks in advance

Are you running active crossovers? You'll have to just find the lpf point that keeps the beaming away

Yep it's the speaker positioning. Happens in my Tahoe also. I think my kick panels with speaker pointing up at my face helped out a lot

I am active. dropping the mids down to 2k with a 24db slope does help, however, madisound says my tweeters shouldn't play below 2500 with a 24 db slope. I have clean unclipped power going to them and never really crank it so not worried about it but figured I should state that.

do you have pics of your kicks by chance? I know you have put a ton of work into your Tahoe.

I have the q logic kicks as well in my 00 silverado. Helped take the grossness out of the door alignment and blend things towards the front but they don't get terribly loud

Having a gap in frequencies isn't a bad thing, if it sounds better. It's not entirely uncommon.

they look better than I thought they would. I hadn't looked at them since I had my cavalier and they did not look good on the cavalier.
