Proper Staging

hmm, running passive is ok but fully active will give you the control youll need. I would HIGHLY recommend at least doing the midbass seperate from the mid/tweet since path lengths will be different. With a 3 way system, your going to need plenty of processing. I would HIGHLY recommend slowing down and doing a 2 way set up and getting that dialed in correctly. 99.9% of guys trying to do a 3 way front end will NOT be able to make it work without the the knowledge needed, and nothing personal....you dont sound like you really understand how hard it is to make it all work together.
Disappointing.

 
Ok, explain:

Accoustic phase

Level matching

T/A. optional

hell the rest......

Point is, explain all that to a newbee.

p.s.

I am talking to him thru IM......HELPING, but go ahead and keep posting your dislikes.

 
PM/IM helps only one person.

Your post was weak plain and simple. Cop-out. Waste of time. Etc.

Threads don't have to about helping ONE PERSON (op), it can be about the title/topic.

No need to spoonfeed every little piece of info, they have a search feature for that, hence, the terms I gave out to help with the search.

 
You've got about 50 pictures of your car, but not a single one showing the kicks installed so we can get an idea of where they're aimed.

One problem you're going to have, and I frankly don't see a way around it is a lack of stage height, based on the pictures you've posted.

Sooo....

How are the drivers positioned when the kicks are installed?

Are the midranges in an enclosure? Should they be? Why/why not?

Let's start there.

Glad to see you in here Bikinpunk. I believe you have the same car dont you? Alot of what you are saying are some of the points I am bringing up. the dash in these cars compared to the kick extends out WAY past any "alligning" you might be able to do. No matter how you look at it (assuming I am seeing what I think I see in the pics) the reflection issues on the underside of the dash and center console cannot be overcome. I look forward to your insight on this since you also have a Civic. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I should note, I have sat in this particualr car and if I remember corectly, these pictures are decieving with the kick to dash relationship.

 
the kicks arent installed yet so no pics of them in the car. the kick isnt exactly enclosed. wholes were cut for the magnet to set in, and the mdf ring was mounted and fleeced over. nexon aimed the mids and tweets to the overhead dome light.

 
Yep, same car. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I've got kick mounted midbasses. I had to do quite a bit of experimenting with foam and MLV to get to a suitable place where I didn't have all sorts of issues traveling up through the dash.

I've not heard a car yet with all drivers mounted below the dash, facing toward the center console that had a stage height above the dash. Not saying it can't be done, but I've not heard it yet.

Based on that, and the appearance that his drivers are not pointed on axis, or even somewhat on axis, I have a feeling that he's going to have all sorts of issues due to reflection under the dash.

But, I'll hold my assumptions until I see how they're installed and aimed.

I agree, Aubrey, that he'd probably be better off to bring the tweeter and mid up top. BUT, having not heard his car, who knows... it may just work fine for him and he not have any issues. It's just my hunch, given my experimentation in the same car. Moving those away from the midbass isn't as bad as leaving the midrange down there with the midbass and having the tweeter up top. IM(short, limited)E, separating the midrange from the tweeter will give you some undesired problems that are harder to fix due to the typical crossover points used b/w midbass & midrange vs. midrange & tweeter. In general, it's just better to keep higher crossed drivers closer together.

What midrange is it?

Have you bothered to see if you should have it in an enclosure? Do you know if the limited space in the kickpanel will be enough, or does it need more? What about treatment of the metal right behind the driver? Have you considered trying to treat that with something so you can cut down on reflection of backwave back into the drivers?

Again, you may not have an issue with this, but they're things to consider at the least.

So, both the mid and the tweeter are aimed at the dome light (not map lights)?

What are the distances of each driver to another? ie: how far is the tweeter from the midrange, and how far is the midrange from the midbass?

See, I knew I liked you. Very good observations and my points thru out IM's. One thing I like about the later gen. Civics....the distance to the glass from the driver position. I could totally have PLD's as close to kicks in a new gen Civic with pods in the pillars/....um "corner windows" //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

OP, this will explain a bit more:

Where do you plan to cross them?

Really, this thread is useless until you get the new kicks installed.

Put them in, toy around, and come back. If you don't have them installed you don't know how you're going to be running them and you don't know what issues you're going to have.

We can guess all day and never be right.

See you in a couple days. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
