Line Array in the works at Stryke Audio.

Brett DiMichele · 06-26-2003, 02:39 AM

I was talking to John tonight and he's been working more on
his Line Array designs using the SA-RTW2 Ribbon Tweeter and
the SA071 7" woven fiber 7" Midrange.

John is working on a sealed version and also a vented dipole
version. I think he will offer a group purchase on the
drivers and xo parts in the not so distant future and I also
think he will offer prebuilt cabinents for those who are
unable to do thier own woodworking.

Here is a picture of the test version dipole line array:

Here are the links to the raw drivers:

I will own these babies!

Brett,

And from my understanding the price will be pretty sweet for the kits too!

Brian Bunge · 06-26-2003, 10:36 AM

Tim,

Should be same as any other 2-way AFAIK.

TimForman · 06-26-2003, 10:36 AM

Do you know how the xo is designed to work? IOW, are all the drivers working in tandem or are they handling different frequency ranges?

Brian Bunge · 06-26-2003, 10:39 AM

That's weird! I was responding to Tim's post, but my response is above his question.

WILD!

Knowing the answers before they are even asked. WOW, you really are that good.

TimForman · 06-26-2003, 01:33 PM

I'm impressed. Can you give me this week's winning Lottery numbers?

Brian Bunge · 06-26-2003, 03:00 PM

Kyle,

I knew you were going to say that

Tim, two of the numbers are 1 and 3 (13's my favorite #). If that's not it, I must be off at the moment.

I'm intrigued with the line array, but concerned about imaging... considering that there's no way to get equal path lengths to the listener (unless the line is curved).

My own experience with WMTMW systems is that they are very sensitive to vertical alignment/path length. I had to tilt my speakers slightly back so that the listener's ear was precisely on-axis vertically (I did this with the help of a He-Ne laser temporarily mounted at the vertical center and perfectly perpendicular to the baffle). Once dialed in this way, the image focus is stunning; however, move your head up or down a foot and the image blurs...

So how does the line array deal with this? Or do you just need to be far enough back that the path length difference isn't significant? Or have I missed some fundamental operating principle (quite possible)?

Well i am not expert but I thnk you are basically correct.
I have heard GR dsigns Line Array at DIY 2002 Texas.
Two Line arrays in Ohio at this years MAF 2003(three actually)
And a Pipe Dream set-up In San Jose California.
And a few years back an older macintosh Line array.

They all presented one helluva a life size image
which did not exhibit pinpoint imaging
(but pretty good imaging).
Think very nice Maggie soundstage but greater
dynamics....MUCH BETTER.

Brian,

Holy Cow you really are a peesychic!

I knew it all along!

Yep the price will be right! Bear in mind though that we
are talking about 24 Mids and 24 Ribbon Tweets so there is
some cost involved with buying this many drivers. But for
what all you will get the price will be VERY good!

Dave,

Carl hit the nail on the head as did you.. Yes the perfect
setup would employ a curved baffle but for most diy deals
that's far to complex. These things should cast one hell of
a huge sound stage, it may not be as pinpoint accurate as
say an MTM or an TM but will have a far broader stage and
more of an openess to them. Every speaker has it's drawbacks
and it's positives. I think the positives will far outweight
it's design limitaions

Tim,

I am not sure yet what John is doing for the XO's we talked
last night and there are just so many ways these things can
be built.. He was thinking about doing the test sealed
version tuned somewhere in the 38Hz region I would imagine
that is using all of the mids to acheive the low end response
not just some of the drivers. That's one of the reasons for
using so many drivers because that 12 mids can play with
more dynamics than one or two and coupled they can play low
cleanly.

I am sure these could be active also (that would get a bit
tricky though..)

More details will be presented as I find out about them.
