Project for a friend over the past two months.

I was thinking that an array of 5 or 6 would put less stress (and thus lower distortion) for each tweeter and provide better vertical dispersion. It would also balance out the power handling of the system.
But if you don't hear any problems, then it is nothing to worry about.

The system looks pretty badass as it is. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

6 Looks like the magic number. but, wouldn't adding more lessen the vertical dispersion? Oh and it does look very hard core.

Thanks!!!
The way I see it, the guy I built them for loves the crap out of them, so what anyone else thinks does not really matter. . .

That is the important part.

You are right in that more would decrease the vertical dispersion if you are thinking in the sense of a point source, but at the same time it would increase the "sweet spot" in the sense of a line array. I guess I didn't really mean dispersion in a pure sense but that the vertical dispersion without comb filtering would be increased.

The way I see it is:

1) the first driver gives you a perfect point source

2) adding a second driver destroys the point source effect (significant above certain frequencies)

3) adding any more drivers only improves it from situation #2 (becoming more and more like a line source)

Sense vertical off axis listening is almost never in the extremes (since you're either standing or sitting) 6 or so tweeters near ear level should be about perfect to cover the sweet spot.

Your project reminds me of this //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif

Ahh... That is exactly what I was thinking. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

If they sounded bad, I might try it, but they are really balanced right now and sound awesome when sitting on the couch, so I will haev to leave it alone. . .

Maybe if I build another pair I will try 6 of them. I could run them in series parallel for a 6 ohm load.

Cool looking setup; just motivated me to redesign the new HT setup a little larger!

Vid?

awesome, that can be one hellavu concert dvd experience. I like it, Is your friend going to leave them up front or place them around the room?

If you build another pair, switching to active XOs would be the first thing I'd change. //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif

Oh indeed.

Active is seriously a kick *** way to go, especially on a project like that.

that is the most ridiculous thing i have ever seen...it's so beautiful, tears are filling my eyes

Beautiful, line arrays are sweet...
