I designing my own kick panels, I have some questions on speaker placement/angles. I'm setting up a set of JL Audio 3 way components (6.5", 4", 1") run through the JL 300/2.
I have an EX so my tweeters at the sail panel are on axis and aimed towards the center of the vehicle. I was thinking about doing the same thing with the 4" midranges in the kicks, aiming them up towards direct center of the car.
Now, in doing so, would there be sound cancellation from the midranges aiming in the same point in the car.
I'm looking for good sound quality and imaging, but I doubt I'm going to do any competions... unless everything sounds amazing.
Another question. Would it be too much to have two tweeters on axis? I was thinking about aiming the kick panel tweeters on axis, but aimed to the direct side the tweeters are. So driver side kick tweeter aimed at the driver and same for passenger side. Has anyone tried this and found the highs to be to harsh.
Thank you in advance.

sounds like it will be a nice setup with the jl 3-ways. if i were you, i would disconnect your factory speakers and only use your new jl components. i think that you will get your best imaging this way.

That would be way too many highs. My shop sells the JL components and those are the ones I have in my car.. Trust me, that's all you need as for as highs go because those tweeters put out plenty.
As for as phase cancellation goes, you should be fine.
Because
1. There are other sound barriers between the speakers
and
2. You don't run into phase cancellation as much with mids.. unless you're competing or just have very good ears.
If you own an Alpine deck with the Time Correction option.. that's a very nice feature if you're looking to get good imaging without doing a lot of added work, you may want to look into that.

Take care of in-car acoustics will be the best without cancellation. When you put your speakers in, take note on how much boost your interior will give you, especially around upper mid-bass(200-600) region. That causes vitually no midbass heard from the car, and causes serious seperation. Passenger will definately hear "mono" sound, and driver's imaging is completely messed up. Trust me.

In my Civic (I don't think yours is different), passenger side has a boost on upper midbass, and driver's side has boost on lower midbass, heard from driver's seat. Anyway, lower midbass is less noticible so I put the balance to L-2, then raise the midrange by 2dB on crossover. This way time correction(0.8ms) will work perfect. Still, waiting for my 31-band EQ.

speaker angle will change instrument placement. so you wont get any cancellation if you position the speakers correctly. this is vehicle specific, even between your vehicle and mine. and they pont whereever they have to, its empirically derived, so if thats both towards the center fo the car, thats fine. if thats some crazy squewed position, thats cool too.
if you plan to TC the midbasses in teh doors to center, make sure you position the kciks TC'ed as well, you cant arrange the kicks perfect with zero TC then focus the midbass through a passive x/o after imaging, youll skew the mids and highs, too.
But I guess nobody will want to place a speaker off axis too much unless distance is an issue. The high frequency roll of is so much faster than the on-axis situation, that will cause localization of farther speaker.

*shrug* the midrange in my buddies car is basically facing the firewall. talk about off axis! his kickpanel is more like a passenger side footrest than a kickpanel.
he wastes me at competition, too, in every staging category.
*shrug* off axis, on axis, roll off or no, its *possible* to get that ideal sound!
another wierd car. the guy used stock door locations, and took first in the entire state. even the judges were scratching their heads about that one.....
what kind of car was it that used stock door locations? Thats exactly what I want to do. Right now I have about 1ms delay difference between the left and right mids. I totaly want to eliminate the time delay while keeping the mids in the stock location and still being able to get good imaging. I'm glad someone was able to do it since it gives me hope. I know it doesn't gaurantee I will be able to do it, but at least I now know in some cars its possible.
it was a 98 accord. I wouldnt expect that to ever happen again, the golden eared mafia here were scratching their heads the entire season over that one.
