this is going to take a long time to upload all these pictures. ill try and do it as fast as i can, first 10 are done, ill work on getting 10 at a time, i might need more space. previous posts will be edited with added pictures in them.

some pictures of the fiberglassing were taken on a friends camera and i can not access his memory card for some reason, so those will have to be postponed.

enjoy as i get them uploaded.


and no, it does not interfere at all with daily driving or comfort one bit.

ill get these glassing pics off the other camera as soon as i can. i have all the pics uploaded as of now other than the ones on the other card. so a refresh might be in order for you :)


i still have some bondo and a few small gaps to fill, but they work and they sound awesome. my stage height went way up, and i have some super killer midbass now lol.

aperiodic is awesome, here is an article on it if you are curious. (pics of the pods he built at the end)

nice work. i understood the bracket peice after you had the speaker pod next to the door. very nice idea. did you pick it up from soemone or had it run through your head one day?
the flexibility you get to deaden your door is unfair. i bet deadening your doors took less than 1 hr of actualy laying it on.
in the pics it looks a little sketchy to me. in a sense of comfort. maybe it's a pic compared to actualy being there that throws it off.
is it at all akward to get in or out of the car?
one thing i would have done with the mounting is to flush the speaker into the pod, but that's just me.
on a side note, the baffle for your subs is starting to sag from time and weight. you might need some new wood or figure a way to brace the center from sagging.

just ran thru my head one day after i was reading the aperiodic article i linked to.


the flexibility you get to deaden your door is unfair. i bet deadening your doors took less than 1 hr of actualy laying it on.

yea it was the quickest deadening job evar, cept the part about taking the door panel apart lol.


in the pics it looks a little sketchy to me. in a sense of comfort. maybe it's a pic compared to actualy being there that throws it off. is it at all akward to get in or out of the car?

not at all. i drove around and the way i used to drive, this pod does not inhibit my normal seating position one bit. and the way i put my leg when i drove before while not shifting is behind the pod near the door (as pictured when im sitting in there) it looks huge, but it seriously is not even annoying, and i can put the door to the second detent and not be bothered by the pod at all. ill take a vid of me getting in and out and you will see :)


one thing i would have done with the mounting is to flush the speaker into the pod, but that's just me.

i wanted to, but as it was, a 9.5" OD for the baffle was rediclious at that point, and my jasper jig only went to 7.5" :verymad: so i had to freehand the baffles (i did a good job IMO) and that took like 45 minutes .... so i skipped that - i wish i had, but the space was premium.


on a side note, the baffle for your subs is starting to sag from time and weight. you might need some new wood or figure a way to brace the center from sagging.

no its not... :crap:

i didn't see the post with the link before. i'm a slow *** typer. lol
(link added to favs)

if i do get my project car soon then i'll be considering that technique for some door pods. just don't want to do much more onto my civic.
as for free handing your mounting rings they did turn out pretty good. though you should of made a new jig as they aren't too hard to fab up. either way your past that point.
what are you planning to use to cover it? are you going to paint it to color match door? or use a such vinyl?

req
05-27-2008, 12:48 AM
i forgot to say, i have some awesome black vynl i will finish these with. i need to do some minor bondo, but thats how they will be all completed and whatever. just thought id put that out there.

thats the idea. the vynl i have is the $15\yard stuff they have at jo anne fabrics. its got a real soft leather feel to it, not as shiny as the stock VW stuff - but im okay with that.

i would have made jigs, but i dont plan on doing this again and i dont have a trace rou
ter bit. so im kinda **** out of luck with that. just a pluge straight cut and a 5\8ths roundover.

i have not gotten to the grill yet, i need to get some different screws\bolts. the ones i had planned on using were just a shy too large than the stock ones. i dont know if they sell T nuts in that small of a threadsize. ill have to take a look this weekend. should be a quick thing.

First off, I do agree you need some fkn grills on those.

Second, I'm a big guy and his speakers really don't get in the way of sitting unless you flail like a 2 year old while sitting in the car. I needed to watch when I got in the car but that's because it's like 3" off the ground and my balance *****.

Though, his old Saturn pods are a pain in the ***. I wish our sister would rip those ****ers out....

Interesting . So how do they sound ? :)

req
05-28-2008, 03:17 PM
they sound awesome. brought my stage height WAY up for starters. without any tuning, i am very pleased with that. but i need to work on getting them all tuned up and all that stuff.

its surprising how little excursion they have compared to infinite baffle, but the midbass is so much more prevalent than it ever was. i dont know if thats a function of on axis response, or if its got to do with the AP, or if its a mixture of both, but i like it. its way more dynamic than ever.

and if i can tune it better, im sure it will sound loads better than it does now :)


by the way

i tried getting the actual glassing pictures off the sd card from his camera in his card reader today, and i tried on three computers - and windows will not read the contents of the card. i have yet to give it a try on a MAC yet, but im going to see if i can bring it to one of those photo places and have them burn the contents on a CD and try that, but i doubt it will work.

so it seems all pictures of the actual fiberglassing process are\were lost. im sorry guys!!!

camera is a moot point, its the memory card that does not work in anything i put it in.

its a micro SD 1gb card that i put into one of those neat little adapters. it worked a few weeks ago when i used it to take pictures of my rims, but its messed up now.


i can see the pictures when the card is in the camera, but the second i try to hook it up to the PC it freezes explorer and turns super gay. :(

The midbass brought your stage up ? How high are you running them ? :)

The midbass brought your stage up ? How high are you running them ? :)

im running horns and midbass. since the horns can not play down to 300hz (id like that tho) i have the midbass playing to 1khz @ 18db\oct and i have the horns playing from 1khz+@24db\oct

so i get quite a bit of midrange from them and i hated the fact that they were like 60 degrees off axis on the left and maybe 40 off axis on the right.


so yea, it brought the low midrange up high. it was weird because most of the vocals and stuff would be up on the dash with the horns, but when the mids would start kicking in with bass guitar riffs or some tom's or maybe a male voice it would be at maybe the height of the headunit - or pulling way toward the speaker.

now there are a few songs that pull down but i think that is mostly due to the recording or MP3 compression as thats really all i have to play around with besides a IASCA disc - which sounds awesome. so i need to get some more listening material ASAP.

So the midbass blends in well with the midrange and horns or do you have midbass, horns, and tweeters? What processing do you have?

I believe he's running a 3 way front stage. Midbass/range - Horns - tweets.


why arent you ever satisfied?


ps: where have you been?
I'm quite satisfied :). I just need to do some RTA'ing. But honestly, I'm too poor and lazy to be truly satisfied with my system. But it's hitting the spot nicely for now.

Pods and the doors came out great, and its def a noticable difference in the doors from the vid.

I like horns, and I want to try some ID CD1 pro full bodies in a few months or so, but im not sure about having the skill to tune them correctly.

Can we get a vid of the front stage in action?

can you give a quick post on how your have your ish tuned... like phase, T/A-wise.

We have similar setups (excluding the cheating tweets), so I want to compare and see if we have similar presets or what not.


I noticed I have better results with one whole side out of phase.

are there any horns that will play lower then that, or is that about the lowest they will play?

I have mine down to 800hz with a 30dB/oct slope. :) that's just because I have full bodies so they'll play lower than Req's. so i win :p:

yup. the CD2 is (to my knowledge) the lowest playing car audio designated horn loaded compression driver available. they are able to play below 1khz, but i was hearing some stupid breakup or something - but only at higher listening levels. so i decided to bring em up one band and crossover 24db\oct. the H701 does do 30db\oct doesnt it... i might drop em back down and give that a go.

as far as time correction\alignment goes i have not had a chance to sit in the car with the RTA or any reference stuff for too long. i THINK i have my left channel out of phase, but im not sure. i have a few tracks i need to burn to a disc that are left\right\center tracks so i can ply around with the phase adjustment...

i did read something the other day - its a neat little trick. you might want to try it (i will)

if you are getting a particular frequency band that is pulling out of center but the rest of the center image is good, you can use the left channel (if its pulling left) EQ to cut those bands pulling left, and boost the same band on the right channel EQ to pull it right. that will be a little bit of a phase\ta adjustment for those particular problem bands.

i still need to sit down for a few hours with some good reference material and do some solid tuning, but i have to get my RTA mic and XLR cord back from a BTdicky. i left it in nort carolina a few weeks ago on accident. :crap:

and there are some veritias horns in the classifieds for a decent price. they always pop up on ebay for 100~200 a pair. i have some full horn lenses for sale if anyone wants some and there are some B&C drivers on partsexpress for a good price to mate up with them. just check my thread in the classified section. but you want to make sure you have the proper EQ\Xover and the devotion to want to tweak them.

Yes, you built these pods of mine... that has a leak.


T/A isn't that difficult by ear. I would say EQ is.

Here's what E Stevens recommended for T/A: (works like a charm)



before using the TA to bring up height reverse polarity/phase of both horns together to see if it raises the stage.

So in this order
- put one side out of phase Horn and midbass driver
- listen and try reversing both horns polarity phase to lift sound stage
- balance left
- t/a left mid only until it lifts up as high as possible then mirror that setting to other side
- then balance center
- t/a left horn and mid together until it shifts center no more than .5 millisecond
- EQ left and right separately as the lower midrange / upper mid bass area 160 to 400 hz range can really lower our stage height. If you dont have an RTA try these settings 125 - 3dB 160 -9dB 200 -6dB 250 -6dB 320 -3dB and see if it is better tonally and stage height wise.

I've done everything Stevens suggest except RTAing both sides separately. That'll come soon enough. I've also done the left/right EQing for the center image.

As of now, I've never had such a high stage and center focus. Tonality needs work.

Too bad you're a lame easterner. You could've joined in on all the DIYma meets we've been having.

So how does the AP enclosure sound different then just IB mounting (or however you have tried in the past)? After reading the article, are you truly sacrificing SPL for sq from it?

im running horns and midbass. since the horns can not play down to 300hz (id like that tho) i have the midbass playing to 1khz @ 18db\oct and i have the horns playing from 1khz+@24db\oct

so i get quite a bit of midrange from them and i hated the fact that they were like 60 degrees off axis on the left and maybe 40 off axis on the right.


so yea, it brought the low midrange up high. it was weird because most of the vocals and stuff would be up on the dash with the horns, but when the mids would start kicking in with bass guitar riffs or some tom's or maybe a male voice it would be at maybe the height of the headunit - or pulling way toward the speaker.

now there are a few songs that pull down but i think that is mostly due to the recording or MP3 compression as thats really all i have to play around with besides a IASCA disc - which sounds awesome. so i need to get some more listening material ASAP.



That would explain it. Had me wondering wtf you had going on :)

gains efficency and some power handeling too. i have 250x2 for these suckers. so i have TONS of headroom.

basically im not totally sure how the FR is effected by the AP, i wanted to do this more of an expierement, i can just remove the membrane if i want to go back to IB, but so far it seems like i am getting much more midbass and better control of the cone because there is less excursion.

maybe ill RTA the speaker with the membrane in, and then out, and see what kind of differences the enclosure exibits. that would be a cool expierement.



when i get to vynl, i plan on using contact cement and a vaccume bag to keep the pressure on the vynl so it has better adhesion :)


ill take pics of that whole process too!!!

i have had success running cd2 comp down to 550 hz

I cross my cd1 pro mhs at 1100 hz 24db slope (run xs65 mids with them) and a boston tweeter mounted up very high just to pull the stage up from 8k hz on up.

this stuff looks nice- but it does look like you infringed on the seating per the images

well, if you sit in the car some day you will realize, the only thing it does is when you get in and close the door as you are getting in, you might catch yourself with the pod between your legs and have to open the door back up to get your other foot in lol.


but other than that, for the past week or so driving with them in - it does not bother my seating - or the passenger seating one bit. i have had zero complaints.
