dali opticon mk2

[BrokenEnglishGuy]

Hey hello
These speakers looks interesting and well priced
But i can't find measurements or something like that... dali said to me when i asked for distortion measurements
''
The impedance curve I have send you is all I can give you.
''
I prefer to see the measurements before speak about the speakers

thank you.

Which exact model of the series are you interested at?

Here are few German reviews with measurements:

As you can see they measure quite decently and have a slightly u-shaped euphonic voicing.

opticon 6 mk2 for my small room xD
But what about the distortion measurements, etc? i can EQ a little that high's since i like it more smooth but what about the distortion

Generally you can see from above measurements that the other Dali models of this series are quite decent regarding distortion in their size classes, like most of current Dali models.

It's worth noting too that Dali is very explicit about the fact that it designs it's speakers to heard with no toe in

where can i found more distortion test from opticon 6 mk2? seems to be a good speaker...

really? i prefer to toe-in the speakers in my room because is more convenient :/, only with toe-in i can separate the speakers at 1.8 meters, if i do not Toe-in i can only separate the speakers for about 1.4m ~

I mean, you can always experiment or EQ if needed, but not only does Dali design its speakers for no toe-in, it specifically tells you not ton toe it in. From the opticon manual:

"All DALI OPTICON speakers are designed to meet our wide dispersion principle, so they should not be angled towards the listening position, but be positioned parallel with the rear wall (see Figure 2). By parallel positioning, the distortion in the main listening area will be lowered and the room integration will be better. The wide dispersion principle also ensures that sound is spread evenly within a large area in the listening room."

Umm I see
I saw the specs from the opticon 6mk2
The ribbon twetter is at 14000khz, is not too high?
I mean the small driver is practically doing everything

Dalis are designed to be listened with little or no toe-in (firing straight into the room) and should be positioned in a long wall setup away from side walls. Otherwise they'll sound "bright" as there'll be too much upper-mid and treble energy reflected towards the listening spot (I see @napilopez already mentioned this).

For the typical UK-style small/narrrow room I would definitely choose a speaker which has reasonably flat off-axis horizontal response, unless you intend to treat the early reflection zones on side walls.
Personally I would go a step further and choose narrow directivity (e.g. Kef) but that is a personal call...

I saw in the page from dali that the ribbon start at 10khz but in the white paper the crossover is at 14000hz, umm

I have a kef r300 and I think it sound nice with personal eq for make the sound smooth ( no problem to eq the speakers since I listening in my pc all the time)
Sadly the kef R7 is much higher in price
My room is 2.8 x 3.3 meters with a weird form plus my bed xD

Oh that's nice, but why it is like that? Is it because higher frequency has narrow dispersion? Then I would assume it is not effective at the lower frequency of woofer and all speakers should have this feature.

Edit: forgot to type some words, made it more clearer now.

And its too much lower?
I didnt know that

Did not even understand what I typed, I have changed it now.

I think that @napilopez means frequency response distortion.

Below is the horizontal/lateral response family measurements for the Rubicon 8, which is flat at 45º (in red):

Yeah, that's what I assume Dali meant. I did read a thing about distortion potentially being directional once, but I doubt that's what Dali meant.

 

[bigjacko]

Ok, I see, so linear distortion............. not audiophile enough for me!
