It sounds like there's no seal between the driver and door panel/grill.

A speaker is an air pump at low frequencies, and it needs to pump the air into the car. If there's any leaks between the driver and grill, the majority of pressure will stay behind the door panel, causing it to flex out of phase with the music.

Carefully mask off the edge of the speaker, then apply a bead of placticine (kids non-hardening modeling clay) around the speaker, and mount the door panel.

Remove the door panel and the clay will give an impression of the spacer you will need to fabricate.

A quicker test would be to listen without the door panels and see if the bass improves.

Basically, the baffle is an integral part of a speaker enclosure. the idea is to get the door panel to act as your baffle instead of all that fine deadener.

Props to the fine pics.

i hope you're not using "Saturday night alright" by Nickleback for tuning.. lol. as much as i like the song, the recording is terriblily compressed and could definitely sound bright.

from your 3rd clip, i could still hear a bit of splashiness from the highs, which makes the highs sounds hotter then it really is. as John has also pointed out.. maybe some acoustic treatment is require to tame it.

not really a product.... but its more of a technique. as suggested by flipping the polarity to compensate the cancellation. but because your midwoofer is playing down to 50hz and only 12db/octave, it will not work.

Yes.

Starterwiz you got a good point, in fact I've thought of that but again installation is an issue. I need to go to a shop and they probably will charge couple hundred dollars for it. That's why I decided to get a custom pod and that will give a really good baffle as well as a much better enclosure than the doors.

No I used those audiophile cd to tune my system. That song just happens to be in the alpine deck that I tried to record it for a fellow member here.

I tried to put blanket on the dash today and it doesn't help that much. Then I pop the tweets out, and place it near the doors like this:


Man it's much better. Although it's closer but it's actually smoother sounding and I like it better than them on the stock dash locations. I really want it be like this but, it's gonna cost couple hundred to get it properly installed. Car audio is $$$...I am gonna go broke soon.

try tapeing them to the apiller

yeah, thats was the whole idea, when i suggested in your other thread.... basically to removes some of the early reflection cause by the windshield. therefore smoother highs (more direct signal vs reflected and minimize comb filtering), which should help with the midbass output.

Indeed midbass reponse improves too. It's amazing how a simple tweeter relocation can do to the overall sound quality. But "midbass" still not quite satisfying yet. I've done 2 clips today.

Settings:
Front stage crossover setting: 50Hz@12db high pass by deck
Tweeter attenuated by -7db on the passive crossover and placed near doors
Deck EQ defeated

Clip1: Righ click and download
This is the same song recorded in the previous ones.

Clip2: Righ click and download
Drum solo with subs on/off repeatedly.

Yes I want to do this. I am thinking to use a nylon fastener for easy angel adjusting.

ok (and i see a pic of the nylon fastener)

Its quite a bit different sounding…

In Clip 1. (#4)

- the highs seems quieter, tonally is slightly better.
- the midwoofer seems to pick up energy around 250hz. (maybe from the deflex pad) but transient attack is a bit duller then clip 3. Overall has a fuller sound.

i would prefer the Focal Plain Chant over the Deflex for treatment tho.
