Default Driver selection, please help

I am looking for a driver to make a line array with 4 to 8 driver par side. The speaker will be working down to 80Hz where they will be cut with a 1' order filter. So I guess the have to have a relative high X-max. I need some help to find the right driver.

Here is a list of some of the drivers I have been looking at, any thought.....

Merrill DCA5.5
Dayton RS100S-8
Fountek 89EX
Vifa TG9FD10/04
Visaton B80
Omnes Audio BB3.01
CSS FR125SR
Tang Band W4-1337SDF
Tang Band W4-1052SDF

Thanks in advance
Frank

all good choices
is price and availability a factor or is quality more important?

A few general thoughts

-80Hz is ambitious for the 3in drivers unless you're planning to Eq them. A 1st order high-pass at 80Hz (presumably active or passive line-level) isn't going to help a huge amount on that score.

-If an array is the object, you'll really need more than 4 drivers per channel

-The drivers you list are all reasonable; you might want to add the Mark Audio CHR-70.3 and Tang Band W4-1320 to the list for consideration.

I would say quality, but I do have a budget... I am looking to spend max 1000-1500$.

i'm on side with Scottmoose 80 hz out of 3 inch drivers might be a strech (or torn surround)
is there a particular reason for wanting this size of driver

Presumably because 3in - 3 1/2in units have an edge for array purposes over the 4in, especially if the latter have a large frame. That said, if you're a few feet back (albeit still in the fresnel zone), there shouldn't be much in it, and the 4in counter with superior LF performance if you're not planning on using large numbers.

Thanks for your replays

You properly right, need a lager numbers of driver if using small units. The combined areal should be around the same as a 8" unit, to be on the safe side.

I found this link to the CSS unit it seems to be alter a bit, it has a lower Qt.
It might work perfectly in a closed or a large vented cabinet.

It's also defunct. The 125 was discontinued several years ago, so you'll need to find a dealer with some still left in stock.

as Scott says, it might be tricky to find a large number of these if a line array is intended, and FWIW, I had much more success with these in sealed or small and highly resistively loaded ( quasi aperiodic) enclosures - when they exceed their excursion limits, you'll sure know about it

Yes, I agree with Chris. As much as I like to support CSS, I don't think this is the driver for you. Chris, what else does Bob have? Would the 126 do it or does that need a tweeter?

EDIT: Did I read that right. Those are $128 ea?

Ok, moving right along...
