The fun has begun, truly 
I have spent a fair mount of time in front of the arrays enjoying them fully. After I replaced te faulty driver overall SQ appear to have increased a notch or two. This can also be due to the drivers still breaking in.
Vacation is approaching and I intend to get started on having things measured

Still on vacation?
I'm in the middle of mine...
I was wondering, did you do any readings on your columns?
I'm curious how much lower your Vifa towers go compared to my cheaper 3inchers. Mine will not produce much under 120Hz.
My setup is limited to send the lowest frequencies from the mains to a sub. The only thing working for now is using JRiver on a computer.

Back this week after 8 weeks mix of vacation, parental leave and handyman duties = no real vacation (Wife makes design cakes part time so I have made her a seperate kitchen for her to work in)
Getting back to work feels nice now, being able to enjoy coffee in relative peace
I havent done any readings yet because I need to upgrade my OS on the Macbook before I can run the required program suites - and I simply havent found time or motivation to get this done yet
I have a Win8 laptop at work that could work as-is...
I do have however spent more time listening to them and still enjoy that very much. In Hi-Fi-mode I use only arrays while in Cinema-mode I also connect the B&W DM604's (LF only) which makes the lower range much more movie friendly Atleast for my taste!

Hej Halair
Welcome to the Line Array sound ..i am still enjoining mine very much,,mine is a pair of LS9
AV123 Focus Line Source 9 (LS9) pictures! - AVS Forum
You will discover some problem to measure on LA ...need some distance to get a good result ..
Just wait to you hear them with a sub ..they will fill the hole room with music..

No worries... I'm playing with movie files (and the good old WOW!) and realised that a lot of low frequencies are only sent to the L/R and leaving the sub out in those 5.1 files (unless I use software like JRiver). So, I was wondering how much lower I would go with the VIFAs.
You could do a quick visual check using this freeware: iSpectrum - Mac Audio Spectrum Analyzer
It would work on your 10.5 Macbook.
Or use Audacity and some free AU plugin.
But again, don't worry too much about it... unless you have some free time and are curious....

Sounds like life got in the way
... at least you have sound!
I saw that beautiful line array by wesayso (it looks great, best of luck and I will be following that), and then this. This is an interesting concept that I tend to overlook before. A full-range line array crossed to a sub will be great for a home theatre system.
Do you simply find the desired tuning for one driver, and then multiply the enclosure volume by the number of drivers you wish to put in? Or am I oversimplifying it?

Got REW up and running, first sweeps made:
These are non-EQ´d sweeps btw and running system in stereo in a untreated room.
I need to learn to use REW properly, any input appreciated
I guess some of those peaks are room resonance. Going down to about 38Hz... that's really impressive! Now I'm thinking about upgrading my drivers!
I usually use 1/12 smoothing. I'm pretty much a beginner in REW as well, but ask your questions and I'm sure we'll be able to answer.
As for my readings, I have a mic stand and I place my omni mic exactly where my head is when I listen to music. Make sure you have enough headroom when you make a measurement, stay in the green, red means you clipped and the resulting sweep will not be accurate.
Wesayso's twin towers are unreal and sexy as h**l
They deserve life!A fullrange line array REQUIRE either LF woofer/tweeter support or EQ (or both depending on taste) - I opted for EQ to begin with for simplicity. Having run mine with woofer support from the DM604's I can confirm this work great for a home theatre setup
As for the tuning I dont have the knowledge to compute the fine details myself so I have based much of my decision making on other similar projects. Yes, its said that the Vifa TC9 like a volume (sealed) just in excess of 2liters and mine are just scaled up based on that. My arrays are simplistic but I think they work very well
@ Perceval; I used 1/6 smoothing for these but is 1/12th used more widely perhaps? From my earlier experience with the DM604's I know that there are issues with the room. I should sweep the DM's to see whats going on

I wish I have his creativity. Skills can be acquired, but an eye for art is something else, especially if it's meant to be something that's functional.Wesayso's twin towers are unreal and sexy as h**l

Since I'm planning on using the Vifa TC9FD for a small-ish bookshelf for a desktop setup, I guess I can play around with volume sizes and get acquainted with this small driver that seems to be one of the favourites around here.
I'd probably won't go so far as making 20+ driver. Though walking into my living room every morning greeted by a pair of 2 metre tall 25 driver line array would start my day off beautifully.

For a computer stereo speakers, a small column of 4 drivers, maybe even angled back, would be really nice.
I have 16 drivers in my small towers, and still looks amazing and sounds great! If I can't blend my towers well with a sub (or actually 2 of them) using the gear I already have then I will think seriously about ordering a bunch of VIFAs.
And yes, two towers of small drivers look amazing... to my eyes anyway! I still look at them in awe ever day! Even the wife appreciates them now.

Thanks. I was thinking that for starters I jut want a 2-3 litre enclosure with a single driver per channel, just to get a feel for what this Vifa sounds like. I'm currently trying to build a 5 in. transmission line, so this is more of a budget side project. I want something that I can pack up and bring along with me to my hostel room. I may also make them active speakers.
If I like how they sound like on their own, I may draw something up.

Hei Bjarne.
Thank you, beautiful LS9's you got there
I havent tried mine with subs yet but I have used my B&W DM604 woofers in combination with the arrays and indeed - it helps
In your experience, what measuring distance is needed in order to get good results (true readings) Forecast for the next few days is rain so I am reluctant to take them outside...
good place to measure in listening position....but try also to measure one unit in near-field-
so can you se if the driver behave well in the box..
do not expect a super linear curve from the LA...so many unit give some hole and top..but it can normally not be heard
i sit about 3 meter from mine..but it will be better about 4 meter,,
mine bass unit is made to go deep( 25 hz) so i have no need for a sub

Got to take the LA´s outside today
No EQ performed for these tests.
The complete set of mdat-file is found here - http://halair.com/rew/Outside.mdat
If anyone knowledgable with REW could try to interpret the finer details I would appreciate that, in case I have missed some quality to these measurement
Nearest reflective surface is minimum 5m away.
