Will DEQX "correct" or "smooth" that out?

It looks pretty good to me SORT OFF that is   If I use different software like raw or holm the FR would be pretty flat. I can apply more EQ to the existing measurements but sometimes it works/sound better without too much eq. Anyway, I think that within +6+6 DB FR is kind of good reference. I think the tweeter is just fine don't need any eq there is suck out at crossover point at 1600 which I don't usually fix with eq I just leave it as it is. A bit Massy is the bass crossover point but..... Subs Left is just fine the Right has nasty dips which I can not fix > unfortunately, DEQx has not separate EQ (left Right) option

Looking very good indeed... I really like the look of natural grain of good quality ply. 

Did you need all the weight that comes with the concrete fill?

I only ask because you can add polystyrene beads (bean bag beans) to the wet mix to save on a lot of weight.

Cheers!

Not sure what do you mean by what sort of finish did you use. These panels where already veneer so on the end I just gave it of wash. The boxes are sitting on anti-slip packers which I have found at bunnings 5mmx40mm round 

Just wondering if you coated the ply with a clear coat or something?

"Doing" the smoothing it out is trivial....  the more complex question is which bits should be adjusted, and by how much (if any at all).   A perfectly flat line is nice to see, but it's important to keep in mind what it represents (or doesn't).   A single point in space, of all the sound summed over time .... delayed, reflected/diffracted sound from the environment.

I have done some setting this morning

Good progress.  You work fast  :) 

 

Can you tell us, for the individual driver measurements ... how were they taken?   I assume the microphone was placed close to each driver?    If so, do you input any other microphone measurements into the DEQX for it to calculate it's correction filter(s)?   Like individual driver responses at the listen position, or the overall summed response at the listening position?

Does the DEQX sum and average out a number of measurement positions?

 

@jkn whats the smoothing the DEQX applies to the measurements? can you change it like REW? (sorry for the pedantic questions, I've been toying with buying one)

Yes I need to as I have only a few days of work 

 

OK, you are right the 3 drivers measurements (3 WAY) are taken on an axis of the individual driver at distance 100mm

 

Measurement for the filter is taken on axis with the tweeter at 0.8m

As I mentioned (I think in this thread) I do not use close measurements for calibration file in multiple (driver) enclosures. Single box (sub) close measurement is fine.

I don't think DEQX does a sum of the measurement positions you have to take them your self if you like. You can do smoothing in DEQX but as I sad before the scale and measurements /graphs look a bit different compared to other software

Speaker looks very nice!

 

What are you trying to show in each of the pictures?   (I can read what they are ....but what are you trying to say about them?)

Good stuff @jkn

 

Do you prefer the scanspeak tweeter over the beryllium's?

They are all good tweeters as I mentioned before however I do like the SS ring more then the beryllium version suit me better I guess

Thanks 

Nothings special in the pictures just a final setting and crossovers...

I did change a little bit again since posting the pictures above !!

Crossovers 

2000/56db slopes Linear phase 

250/48db slopes Linear phase

80/24db slopes LR

max boost 6db in calibration templates/bass&sub

Final 2 pictures time alignment between the mains and subs

Wow they some steep crossovers, i love steep xo's but haven't gone that high (normally 24db/o)
