after finding out that my rockford speaker doesn't fit my civic front door, I decided to fg a kick panel, I have read that you have to put the mid facing opposite b-pillar, but what about the tweeter? my component comes with 2 removable tweeter, should I leave them on the mid? or install them on the a pillar and at which angles?, any advice would be well appreciate. Thanks

oh, and by the way, what kind of grills are you guy using to protect the speaker? the one come with the speaker isn't fully cover the speaker, i mean anything about the size of a big marble can get in there, what kind of grill should I use?

You wanna keep the tweeter on the same plain as the driver and within about 6 inchs so build the kicks to accomidate both the tweeter and the mid. As for angle, thats kinda trial and error. I bet thats what you wanted to hear :). As for grills, personally I have a set of pioneer rev components that have been in kicks for a couple years now and if you ever say the grills on them you would beable to see how large of opening they have, marbles pass through without an issue. But as long as the speakers cant be kicked by a foot or something to that effect they should be fine, just dont play chinesse checkers in the car.

but what about water? I mean if it's raining outside, and when you walk in, waters going to get in there right? and since the openning of the grill is too big, if you have like rock stuck in your shoes, once you put your feet on top of that, rock might fall through. about the tweeter, the instruction booklet come with the speaker advise to put the tweeter either closer than 2 inch or farer than 7 inch, never in the range of 2 to 7 inch. The tweeter can be mounted right in the center of the speaker. what I am asking is is it better to have them mounted on or separate them?

I believe in the 2 to 7 inch range is better than further away. That seems to counter a lot of what I've read in various speaker building books. DYohn, Haemphsyt, any idea why they would suggest this?
As for mounting in the center, go for it. It might make the kick smaller and easier to work with. Having said that, depending on the design of the mount itself it could interfere with some of the high frequency sound from the midrange. I'd probably mock up a quick box with cardboard and try it both ways in your garage before starting kick design.

Woeful, you can't waterproof it and still get sound. But you can put screen into the inside of the grille before you snap it into place. I think the manufacturer is warning of phase cancellation issues by making the point about the distance range between the tweeter and the mid....a couple inches away and the phase will be close enough, then a few inches further you may end up with a 180 degree phase shift (and cancellation). Double that distance is more likely to come around to 360 degrees and be in phase again. Every vehicle is different, so experimentation is key.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Good thinking stevdart - I should have put your name up there in my call for opinions too. :-)
If that 180 degree phase shift were the case wouldn't the solution be as easy as reversing polarity on the tweeter?

:) Another thing you can do when setting up your components is to experiment with reversing the leads on the tweeter, which will reverse phase to it. You may have a good install location for them and find that reversing the pos and neg wires will make the tweeter and your overall sound better. When I was building a crossover for my home system, I began to realize this when I found out that the 12 db/octave crossover itself normally causes enough time delay to cause the tweeter to have to be reversed to stay in phase with the woofer. That made me realize what small differences in time or distance can make on the overall sound of a tweeter/woofer combination. When you do this install, allow yourself the time to play with all these things. When you're all done you'll be satisfied that you've found the best positioning for quality sound. kfr01....you know I'm going to butt in anyway....;) Ha ha, you got that last question in there after I started this..........when I start thinking as you do I know I've made some improvement! ------------- Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Time alignment or acoustic phase alignment is a very important loudspeaker design criteria. It is much more important in critical listening situations like home audio or studios and much less so in car audio (since cars basically suck as acoustic environments.) It's a law of physics first described by Joseph Fourier. There are so many important loudspeaker design theories on this topic from people like Joe D'Appolito, Bob Carver, Henry Kloss, and many others that it's hard to recomend a starting point... HERE is a very nice web site that explains the theroy and how to design for it, largely in non-engineering terms. In general, placing the tweeter within 1 diameter of the woofer and on the same center line is the best approach. Including things like horizontal ofsets, offset baffles, acoustic plane alignment etc. is probably overkill for car audio, even for SQ comp. Electronic time delay compensation is the best approach, IMO. A properly designed coaxial (AKA "point source") loudspeaker is the theoretical "best" design for near-field monitoring. ------------- Support the12volt.com

thanks for all the input, going to try out today, i have just finished laying out all the wire yesterday.
