Completed neo3/pl14 line array - Thanks!

This is just to say thanks to everybody who gave input on my line array project. I'm done, they sound amazing. I have documented process, measurements, results, pics, references, etc in the website referenced in this message.

Theo,

Very impressive results. Glad to be of some help.

Give us a break with those 350K to 750K image sizes. Cant you get them down to a reasonable 60K? We don't all have broadband you know.

I second this request! I couldn't view all of it, it was just too sloooooooooooooooooow.

Nice work though. Are all those expensive tweeters necessary since only about 10% (pulling a number out of the air here) of the power spectrum is going to be handled by the tweeter package?

Hi,

Was there any reason you used the Neo3 over the Neo3PDR?

Also, a question for Jim G. - For a very high quality array, would your first choice be to use dome tweeters or some kind of ribbon/planar tweeter? Assume that a single planar and a single dome sound the same. When you put 12 or more together in an array, which is typically the better solution?

I have a hard time finding dome tweeters that are small enough to have a good center to center spacing. The best I can find are tweeters that have a 2.125 inch face plate.

Thanks.

Tomcat,

On tweeters in a line array: I would choose planars or ribbons over domes everytime. As you note it is difficult to find small diameter domes that can be used in a line array. The 6" to 8" planar or ribbon tweeters are ideal for this application when arrayed 8 to 9 per side.

Thanks Jim. I will be strongly considering the Neo3PDR.

I wonder how this:

would compare if you put it head-to-head with this:

(The one at the far right, the 6-6.)

They use the same tweeter, but I imagne the crossover design also has a lot to do with it.

and they use a less expensive tangband mid-woof

And they cost $8900, $14000, and $26000.
