Tomorrow i am going to calibrate my Dutch and Dutch.
I cant use Roon and Room Correction yet, so i am going to calibrate them using the
24 Parametric EQ filter built inside them.
Cant wait for Roon to do proper filters!
Ill take some before and after curves. My goal is to eliminate the biggest problems in the room and
make the mid-range a little more dominant. Thats how a like it !
It is very easy to use convolution in Roon today. Audiolense, Acourate and HAF produce nice filters. You could even use Dirac, but then one would have to create a useful impulse response through Diracâs correction. Like @KMan is talking about here: Near-field Room correction and crossover in Roon
Good luck!
Thank you !
This is some new grounds for me !
Is there an ETA when these speaker will receive full Roon Ready certification? Anyone have any idea what is causing the, now, 8 month (?) delay in this being given? Technical issues of some sort?
It is almost over 1,5 years I would say. No ETA available.
I believe Roon has already done their part in testing the 8c. Dutch & Dutch is listed on Roonâs network partner page. See Brice_Langâs post further up the thread. The delay is still there though, probably due to some issue only D&D knows about.
They are on the list since monthsâŚthey needed to overall something in their firmware update method and will then continue with Roon. Roon is not that difficult, but the perfect reliable sync between the speakers is. Roon does not support âmaster/slaveâ devices, so they developed something proprietary.
Roon supports master/slave, 99% of the active speakers are built this way.
Dutch and Dutch 8C is Master/Master⌠They need to be 100% synchronized, that´s what causing the delay. And the problem is not easily fixed⌠of what ive heard, is that a master master configuration will be better than a master/slave.
This problem is a new one âŚ
Hello @mathias_belevid !
This is the group i was talking about 
Thank you for the help today. My D&D8C sounds much better, even the little we did with Parametric EQ did a lot to improve SQ !
I cant wait for ROON now, more then ever. I really want to unleash the power by applying room filters directly in the source - ROON. That will be INSANE !
I have dreamt about this for a while nowâŚ
Not really: There should be one master clock! And Roon does not support synchronization between âendpointsâ from my knowledge. Master/Slave is also not supported from my knowledge: One Master is distributing the audio signal to another loudspeaker (which is not a slave, distribution is made by own design of manufacturer e.g like Kef LS50W with a cable between the speakers, only one speaker is âspeakingâ with Roon). D&D is syncing two endpoints to each other. There must be one master - how can it work with two master (which means two master clocks).
ah, yes. I spoke more in general, like the LS50W. One âmasterâ the other âslaveâ, one clock, one endpoint. Speaker speaks to speaker
I believe thats the problem⌠D&D8C = 2 roon endpoints = 2 clocks = needs to synchronize.
But i might be superwrong âŚ
you are totally right - two clocks needs to be synchronized throughout a home (!) network. This protocol has to be robust.
As @mitr said; his review pair was like D&D described it to me last year:
Roon streams to one of the 8câs in a zone. This master 8c then redistributes the audio (via AES/EBU - my comment) to the other 8c('s) in the group. All 8câs sync to the master clock.
I still think this is a good way to do it even if is appears âless elegantâ than two networked speakers that sync.
Have you done some Parametric EQ on yours ?
Both speakers appear as one endpoint! Sometimes it was a little buggy (it is still beta), but it appeared as one system. There is no direct physical connection between the speakers: both are connected to the ethernet and sync over it.
hmm, missed this , and very interesting.
Are we sure this is the way its going to be in the end, or just a quick fix for the reviewâŚ
then i dont really understand the almost 2 year delay 
Not at the time of the demo + I wonât join the D&D club to do it later
exactly ! then it was not a dream âŚ
Nevertheless: The solution is ambitious, but I think the âold schoolâ, reliable and not proprietary way is much better. Why? You rely on proven standards and the end result for the customer is the same
I am sorry, quite tired.
So you dont own a pair ?
