coaxil vs. component

[Innovative:Cory 10+ year member]

If coherency is of any value to you, a coaxial driver will always have the advantage of being as close to a point source without actually being one. The only improvement would be a single full range driver but that poses a new set of advantages/disadvantages.
The center of the tweeter should never be any further from the center of the woofer by more than a full wavelength at the crossover frequency. For example, if the crossover point is 3k that amounts to about 4.5". Depending on the particular rate of attenuation per octave you will have phase/lobing issues to deal with if you decide to make that distance greater.

Something to consider.

So I guess all the guys who build the Championship winning SQ cars are wrong...//content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

op somthing to think about...a properly installed component system will sound better than a set of coax's.....a poorly installed component set will sound worse than the coax's.....

Well, I won't tell you where to put everything but let me be more clear about what I was trying to illustrate.
Let's take the ubiquitous 2khz crossover point. Sound travels at roughly 1130 feet per second.

1130/2000 = .565'

.565*12 (to get inches) = 6.78"

So roughly 6.75" is the longest distance you would want to separate these components ideally. More than that and you will begin to destroy the constructive relationship between the two.

You are forgetting about absolute/relative phase completly....

This is absolutely true but not all inclusive.

And please, there's no need to get sarcastic. That's what gets in the way of every constructive topic on this site .

I didn't get into the fact that steeper slope are more forgiving of separation and placement because I was interested in keeping this conversation simple going off of the OP's question. Indeed what's more important when large distances are involved is that the crossover point be much lower, but again, that's another detailed tangent to go off on.

And the day I let a judge in the lanes be the point of reference will be my last day in the audio field.

In fact I wasn't because I happen to design and build my own filters to suit the needs of individual drivers.

Try separating two drivers that are using a 6dB slope. That's the full embodiment of absolute/relative phase.

6dB slopes are for bitches. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

6dB slopes require the most from drivers with regards to smooth behavior and power handling abilities.

I think what you meant was 6dB slopes are for those who have an idea of what they're doing.

Are you helping the OP?

ok, so can you suggest me a good pair of components for around 100 bucks.
