I missed which driver that was as good for less. Would that be the cousin paper cone tc9fd at less than half the cost? Or was it an FRxx?

Oh yes eq. is nessesary. Not that much, but absolutely nessesary.
The one with Aura sound is eq. by a Behringer deq96 and is palying in my HT room. Does a good job here. Crossed over to 4x 10" subwoofers @120Hz and aided in the top by a 19mm ring radiator.

The Vifa source is my main reference speaker. Eventually I will mate it with a IB subwoofer as it cannot play loud enough in the bottom octave to my taste.
I use Audiolense to eq. it and room correct at the same time.
These are amazing speakers!!!
The best I have had. A little trick:
Put a little Isopunkt made thinner with turpentine on the paper cones and let oit harden in UV light. Takes them a step up in clarity and definition.
It is closed boxes both of them.
The alu boxes are actually a little too small, but when the subs are ready, makes no problems.
They play insanely loud when crossed over about 80-100 Hz.

So the point of the Isopunkt is to make the cone a bit heavier? Not stiffer I presume? Dit you just paint on the mixed down Isopunkt?

Merry Christmas by the way

I tried to find more info on Isopunkt and ran across this article, which has some interesting observations on the big picture of hifi setups and a little bit on what Isopunkt does. This guy is a diy nut, he weaves his own suspensions from nylon fishline, glues coins on the backs of tweeter magnets, makes shims to smooth out surfaces where possible, etc. One trick after another. Anyhow, it sounds like Isopunkt is simply roofing tar and adds mass and elasticity to hard cones. I would be surprised if we could get it easily in the US, but probably equivalents in roofing business.

Merry X-mas and Happy Holidays folks

I got a stash of BB/BB quality Baltic Birch ready, now all I need is time .
I had some aluminium water yet cut for templates and the feet for the speakers. I'll update with pictures if I finally find some time to work on it.
I'm still wondering if I should use wooden dowels to stack my multiply or run threaded M8 rods all the way trough.
The enclosures will be sealed with epoxy or fibreglass, would it be save to run a rod from top to bottom? Possibly with rubber rings under the nuts to allow some expansion/schrinking. I'm not that sure the sealed enclosures will not expand or contract after sealing with epoxy/fibreglass.

Thanks, I noticed several of your builds using the Vifa TC9 and your mp3 files... it made me a bit more confident in having 25 in a row .

First steps, a lot of work ahead:
Click the image to open in full size.
On the left a finished set of routed ply, on the right the rough cut and my water yet cut template..
My DIY table (Workmate with a router between the vice, bolted to a piece of plywood) works. You can see a small stud behind the cutting bit to make it easier to start cutting by easing in using that stud.

It's a lot of work but I think it will be worth it in the end.
It seemed more fitting to post to this thread instead of the Stupid Cheap Line Array one.
It may be stupid to try it like this but it sure ain't cheap!

Are you still happy with your Array's?

Hi wesayso

Sure I am...!

The very best I have ever owened. They continue to surprise me, whenever I make changes in amplifiers, cables or front end, it just comes through very clearly.
They seem to have no character of their own, and that is about the best I can say about speakers!

Good luck

Koldby
