Help with Line Array wiring_Power tapering

[sqlkev]

I just ordered 32 of the 4" full range pioneers and will be picking up Steve (apexjr.) $1 tweeters next week.
I'm thinking of going with the example on Dr. Griffin's paper to avoid complications.

Here's the paper on the line array (http://www.audiodiycentral.com/resource/pdf/nflawp.pdf)

How would i go and wire like what he has in the example?
I am very new at this, so any illustrations will be fine

I attached the picture from the .pdf and that's the configuration that i want to do.
Thanks in advance for any help or suggestions

This should get you there.

I think now i just understood the wiring combinations illustrated in Dr. Griffin's paper and now the whole thing makes sense (sorta)

so if my amp is either 4 or 8ohm stabled and want to go the tapered route..i would go with combination 3 and 4?
When first looked at the combinations...i thought i had to combine ALL together..now that would be a huge mess wouldnt it?

I'll try to make a diagram tonite and will post..
maybe someone could correct me there..
Thanks in advance

When choosing how to wire your array, you need to have an idea of what amp, or type of amp, you will be using. Some amps, like tube amps, may work better into an 8 ohm load. A lot of solid state amps work well into 4 ohm loads, but not all.

I plan to build line arrays later this year.

Thanks for the reminder..
i have a pioneer elite receiver that i plan to run the line arrays for awhile..
if im not mistaken...it does go down to 4ohm..

question for you guys ..

let's say that i have an array of 16 8omh speakers ..

if i use 4 sets connected to each other in series
and inside the sets are connected in parallel


this would means 1omh for each set times 4
so 4omh right ?

what other influences would it have on the amplifier?

would the amplifier sees it exactly like a 4omh speaker?
or is there more to that?

i think that current migh change also???
do we care about that ??

Fellas,

There's a couple of diagrams at the Zalytron website that might illustrate the power-tapering hookup a bit better.

Look on the Line Arrays page and examine the wiring diagrams of the multiple combinations at the bottom. Some are tapered, some are not, but it's a bit easier to visualize with these diagrams. Hope that helps.

Cheers,

Davey.

Davey...
that is PERFECT..

i think this is the wiring diagram for set of 12woofers that i'm doing
http://www.zalytron.com/Schematics/by12dia.gif

this wiring would make the array to have 3 different sets of drivers playing at different levels correct?

if i were to wire into 4 sets...would the line array sound more "pinpoint" at a certain height?

so they use paralled series of speakers ..

for my example :
4 series of 8ohm speakers would give 32ohm each
paralelled together would come back to 8ohm ??

mmm ok

ok sorry for my impotant posts ..

i just understood everything in the connections by readin the nice document suggested above
