Which would sound better. If rounds would sound better is it easy enough to make a plate for use behind the sail panels?

 

Rounds are always better.

 

LOL! I was about to ask this same question!

What's the reason behind rounds being better, mnorton?

It wouldn't be hard at all to make a 6 1/2 plate. Just use the original as a guide.

 

Au contraire, mes ami!

Round or square or oblong, it makes NO audible difference

 

Basically it amounts to a physical tension (surface to air) issue on the cone.

If you have a round cone it will have somewhat equal tension 360 degrees around the cone, and will thus result in a more accurate "air wave" representation of the electronic signal that stimulates the cone (voice coil to cone). Sounds like a bit of B.S. I'm sure until you think about it in a little more depth.

For example: A 6 X 9 cone has inherent waveform distortion "built into" the shape of the cone. The physical tension on the surface changes all the way around the cone. Stated in another way, the tension at the two ends of the cone is much different than the tension on the two sides. Round cones have somewhat equal tension all the way around them; Oval (or square) cones do not.

As a result: For the very same electro-mechanical reasons, an Oval cone will ALWAYS tear itself apart before a Round cone will.. The physical movement (the throw, or the actual cone distance traveled per electronic stimulus) results of a waveform from a Round cone will be physically more symmetrical than that of an Oval cone. Thus waveform reproduction is going to be more pure and less distorted. Your ear can hear this difference....

Drop a pebble into a pool of water and then look at the results. I think that very common example describes the wave front events pretty well.

There have been many attempts at compensating for the inherent physical differences in the creation of non-round cones, but to date, Round cones are still the best at reproducing audio waveforms.

 

Seal those panels up and go with a decent set of 8in subwoofers. It's very easy to pull out the steel 6X9 panel and make a wood panel to mount whatever you can fit back there.

 

I will believe it when I hear it, and so far I haven't heard it. You have made the case that round sounds better but that is a purely subjective assessment. Round may sound different but that is not necessarily better.

Examing the extremes to which various shapes can be subjected to, with regard to electro-mechanical stresses, only means that round ones can, on average perhaps, absorb more punishment before flying apart. Distortion is at such an level in this event that an accurate measurement of the fidelity of the produced sound to that of the original sound is impossible to ascertain. And doubtless the resultant squawk would be less than pleasant

 

For large Bass cones, or Sub Woofers as many people like to call them, there really isn't a lot of what I would typically call "music" coming out of them. Basically all they are doing is pushing large volumes of air. Fidelity in this case to me really is how well they can push that low frequency spectrum of air waves. Do the Bass tones emitted sound "clean", or are they "muddy"? Do the Drums sound like they are full, and do they seem to have the proper tones?

Basically what you want is a cone that can push out, and then recover back to a neutral state quickly and without much physical distortion along the way. Big cones with long throws can push more air. Round cones can do that well, better than oval or square cones can.

For me, I like the sound that a round cone puts out. And actually I typically like the sound of paper cones better than plastic. That's the beauty of audio, if it sounds good to you, then it is good. The shape of the cone doesn't really matter.... If you can't hear it, then it's not there.

 

well I won't argue, but I'll tell you this.. I pulled the 6x9's and made a plate with 1/4" plywood and installed a 6.5" infinity kappa component set. Sounds grrrrreat!

 

I still prefer 6x9's with an amplifer...

What ya need to do though(like I've done on the last two Camaros) is convert your dash speakers to 5.25 and put in some components!

 

There is no real way to get good imaging out of tweeters in those back sail panels. If you really want to keep the 6x9's I would recommend putting in a set of woofer only 6X9's like Kicker and McIntosh used to make. As for the front stage, either do door build outs, or put kick panels in; the only time I would recommend using the dash speaker location would be if you want to make some kind of front stage fill with a set of attenuated tweeters. Really the bottom line for a Camaro system is how much time you want to spend and how much money you have to put into your system. If you don't mind the way the stock system sounded when it was young and fresh then just buy a cheaper set of efficient coaxials and put them in the stock locations, if you want something that will sound powerful and realistic you'll need to change some things about the layout of the entire system. Lastly to keep on topic, 6X9's and 6.5's will both sound terrible if they're driven into distortion. However if you keep them playing clean the 6X9's will offer some more low range extension, something that shouldn't be an issue if you're using a subwoofer.
