buh we went in the backyard

[pimptacular]

i wonder wa u was doing in the backyard

but if your car only coulda sound as good as it fast

[pimptacular]

ok ..so for a lil update i got back the arc amp and its working flawless..customer service ftw..

my car getting tuned today and i nervous

[pimptacular]

ok so i have to re aim my kicks

[SR]

relocate the tweets and if no improvement well u know what to do


door speakers need to be mounted more firmly and possible more sealed at the back or replace the door speakers

mids need to reangle for better imaging

however total sound of the system was quite good after some re tuning

tweet response could be better but he has some homewrok to do first before thinking of buying any more equipment

[rigman00]

good man....hope he learning

[SR]

yup very good attempt at a diy with limited tools and no help

[pimptacular]

2way FTW
but after you guys stopped by i started looking over my build log pictures and noticed some stuff i deffinitely need to improve on..

those tweeters more than likely are going to be moved or replaced!
especially after hearing samiir car and the difference in the staging and the location of the tweets

i going to dig into my doors and dampen it out more as well as try to chamfer it as much as possible because majority of the driver is in the stacked up baffle which i think would affect the airflow..

and re aim those midranges because when we listened to it the way it is currently getting a pretty imaging on the higher frequencies but lower frequencies of the voice it tends to get pulled to the left..when we angled it a bit upwards and to the opposite listener it became more stablized

and that was 1 of the first things shazard said needs adjustment when he listened to the car and TA wasnt set and he was on the passenger side..when you experienced you really experienced.

but in my defence i havent had any cars to use as reference or heard a car with any sort of sq set up in a very very very long time..but once again i got work to do and i intend to have it sounding better when my semester finish or when i not overloaded with work

[SR]

if u have time b4 we leave lets drop one of the door panels and see what can be done to improve it
use samiir's car as a reference for stage depth and height

dont be discouraged the 3 way setup can work but its gonna take more time to get it right

use time alignment as the last option and not b4

once we can fix the correct angling of the drivers time aligning will come in easy and u should be able to just make minimal adjustments and notice the differences right off the bat

[SR]

tweets in yet????

[pimptacular]

not yet..i trying to get some time..i have an exam this week and some papers to do..so soon as soem time free up i getting started on that and working on the doors as well cuz i have to take down the doors in anycase

[pimptacular]

tha some stuff i did to the car nothing big really but it does change the exterior quite a bit

[Sully]

Like you finally wash the car?

[pimptacular]

so i looking for some advice..what can i do to help fix my focus issues?
i have a pretty flexible sound processor.. i get a pretty decent center but it fluctuates and gets pulled to the left at times anyone care to shed some light on what i can do to correct this?

n no the tweeters didnt go in yet end of the semester nearing

[Sully]

Is it that the center moves with a change in frequency?

[pimptacular]

yup thats the one..posting it here in hope that other people would chip in and maybe learn something

[jeff]

state cross over points

if you have no tweets is it just the midrange playing?

[SR]

question is

did you change those pods and angles of those mids??
also did i install the new tweets and whats the angle of the tweets in refference to the angle of the mids

[pimptacular]

well ive been doing some research outta laziness just not to play around with speaker positioning to try and find a way..and i still havent done the tweets, end of the semester which is in 2 weeks

but none the less, the positioning if when i do change them 1 positioning i am going to try is angling them upwards the sunroof screen handle
the positioning of the tweeters i can run them completely off axis firing them across at each other on the dash because of the pedestal , i think thaz how u told me to try them out when testing it out...cept u said to put them on the pillar and when i looked at the positioning its alot easier to mount onto the dash with some double sided tape or something to that matter

as for jeff xover points ive been fiddling around with trying to see if i cud find any solution through processing is 200hp, 3.2lp on the midranges each at 24db slopes
and all my slopes are 24db and no over lapping..

i also tried it trying to point source at 180 and 8k at 24db

i know my currents tweeters are a flaw in the system after much listening,
and what happens is that the center fluctuates according to the frequency where it gets pulled to the left at lower notes but at higher notes it pretty dead on

[jeff]

i may only suggest on what i am seeing in the install

because the midranges are not all the way to the sides and are 90 degrees in front, this may lead to beaming of upper midrange frequencies and may cause issues with imaging. To help with this you can either angle the midrange where it is now, or place the midranges all the way into the kick panels.

after you have done either you may then proceed to electronically delay the speakers according to bandwidth. This is done to avoid different freqs "pulling"

[Sully]

To help with this you can either angle the midrange where it is now ..."pulling"

This isn't new news to him, but I understand the lack of time that he's dealing with right now. Hopefully in about 3 weeks he should have a solution.

[pimptacular]

so today i was stuck in traffic and was bored so turned off my tweeters and bump the xover on the midranges up to like 18k

and the center stablized a bit more and actually sounded better without the tweeters
but i still going to redo those half ass pods tho
suffered badly from the rainbow effect


ive always heard people talk about how important tweeters are to staging but never anything really about imaging..and after some thought speaker placement really that critical, i always figured u could get away being a little lazy and let ur processing make up for the rest specially with TA but jeeze i honestly never thought 3way would be this frustrating!

[SR]

i take it the new tweets not in as yet

[pimptacular]

end of the semester
workin on that car is my mission when the semester finishes this week
