Full range line array

[inrank]

from my other thread, it looks like i will buy my crossover components for my other project from america, madisound looks best.

and i was thinking as i am already getting stuff from there, should i get some other things while i am there aswell, and seeing that they have some very cheap drivers there that i could get for a line array.

it would be used at home (as i am uni with my tannoy cheviots) and wont need to go all that loud, was looking at....

Foster 5.25" wide range (up to around 5khz) $3! (say 8 per side and get a seperate tweeter)
HiVi B3S 3" $9.55 (4 per side)

would this be a good idea.

And this is not another one of my 'crazy' ideas

Thanks

I am thinking about same stuff.

I consider drivers like Aurasound NSW1-205-8A and NSW2-326-8A for line array towers.

great idea!
i was experimenting with something similar with great results

A while back Parts Express has a deal on Pioneer 4 "
for 50 cents USd each.

At that time Bill Fitzmaurice put together a project
for those which he may still have at

billfitzmaurice.com

I bought int o the deal and got 16.

But I have only one completed box wired to the
specification but no tweeter treatments.

A bit of a discussion on my build is over in the
full range driver forum:

That build was slow going and just recently got it stood up and
playing. So I'm interested in tips for line arrays.

I had questions in the thread about box volume but also
wanted to do minimal cutting on some reused pieces to retain
some round over corners. I'm doing a/b comparisons with
a BIB as I write during a radio broadcast.

At this stage of things the BIB has it all over the line.
The line takes more volume to get going too.

hi loninappleton,
my line array has no box, its open in the back
you are not going to get much bass out of 4" speaker anyway
why not open baffle line array
with subwoofer

Intresting...OB line array.. with bass augmentation...mmmmm I am thinking on this also.. Can you curve the top & bottom forward to reduce combing effect..? seems I Have seen this before on arrays..I have a spare ribbon pair that I could also use in the project.. just need to figure out which drivers to use..& get to 150-180hz

Hi guys,

Please remember, if you do a closed or vented box, each driver should have its own seperate chamber, or maybe better split up in sections - otherwise you will get a nasty low end ressonanse, related to the tall box

Maybe three sections, with top and bottom tilted/slanted(?) forward

just my 2cents, good luck

if you cluster your tweeters in the middle, or use just one tweeter in the middle of midrange line array, there is no combing effect
you can bend the front, I have seen it done, but I believe its way too much complication for questionable benefit

what about the....

Vifa Logic BC14SG69-04 $15
http://www.madisound.com/cgi-bin/ind....9858&pid=2142
Peerless SC14SG49-08 $15
http://www.madisound.com/cgi-bin/ind....9858&pid=2184

both go up to arround 4khz, what frequency does lobing start and what freq should i cross them to a tweeter, and how does the array of say 8 of the drivers effect the efficiency?

Hi, I would think that Visaton FRS8-8 or FRS8-4 are the ones to beat - looking quite nice and at 10EUR ea you can afford a couple more

edit, or maybe better if you can find the Hivi A2S
