Dutch & Dutch 8c: pre-Roon Ready thread

The point of the night mode is to reduce the bass so your neighbors and family are not annoyed. Or so I assume.

That makes sense. If someone is experiencing issues with the speakers randomly sounding flat, night mode could be a culprit then. I thought the moon icon was just to turn the LED off but then I went deeper into the settings and saw both a LED off mode and a night mode that I didnā€™t even know existed. My question is answered at least!

I made the same mistake! Thatā€™s how I figured it out.

Good suggestion. I am aware of that night mode icon. I sometimes think a track has very little bass and then check night mode and find I have accidentally switched it on. I wish that button would be moved elsewhere. Not sure if that could be the ā€œflatā€ sound. I will check next time it happens.

Currently all my audio devices have disappeared from roon. So even if roon certify the 8Cs I think a separate streamer is a good idea. Or will the new 8C update include other streaming options? Airplay, radio etc?

Whilst I never have any issues with accidentally hitting the ā€˜night modeā€™ button, hopefully the app theyā€™ve been talking about solves some of those layout issues.

Im eager to see what the next update brings. They said on another forum recently that Dutch & Dutch have done their bit and are now waiting for Roon to finish the certification process. Hereā€™s hoping it doesnā€™t take much longer!!

Donā€™t hold your breath. I imagine roon are busy fixing all their 1.8 problems right now.

Please give us a volume slider in lanspeaker!

Thanks, J.D. I did and it makes a big difference.

Listening to Kranium now loud. No one is home. These are better than my last system.

You Happy makes me happy :slight_smile:

I found the inbuilt room correction to be limiting. Using convolutions via the roon core generates much better results.

Iā€™d suggest that a combination of the two would give good results. Use the inbuilt EQ to tackle the two (or three) most offensive peaks in the bass region (under 100Hz) then convolution in Roon for the rest. Measurements for convolution with the bass EQ in placeā€¦

But convolution can handle it all , no ? Why add another DSP process?

Sorry to jump in here - you are already doing DSP in the 8C just by setting the rear and side wall distances - doing further DSP in Roon using convolution is where you are adding another DSP process

Yes of course. But as I mentioned, convolution can handle the EQ itself, so why separate the 2ā€¦

I use convolution to handle DSP crossover, room EQ and time domain correction (Audiolense XO)ā€¦ I donā€™t understand why any of these would need to be split out, for a certain frequency range?

In the case of the 8c D&D has made a specialised EQ available for the purpose of dealing with bass/room. If the convolution filter used is amplitude only (i.e. from REW) it could also do the bass correction. But I assume the convolution in question also deals with the time domain. Then I would prefer the D&D EQ for bass correction (because it is ā€˜partā€™ of the speaker) and create a full range convolution filter with time domain correction on top.
I also use Audiolense XO with TTD. My best example is when I used Devialet SAM for my speakers and a Audiolense filter on top of that in Roon. SAM is of course more specialised than the D&D EQ, but it is DSP. The result was simply stunning. Iā€™m not afraid of using several DSP instances to get a good result.

Just intrigued now - why are you doing DSP crossover on the D&D 8C - are you using subs? plus bit confused with your use of these speakers as to why you need time domain alignment of them? My own view is doing any EQ in Roon is altering the source - I just work on the premise that doing less is more effective in the long term.

Iā€™m not @dabassgoesboomboom obviously but a short comment on this. The 8cā€™s are already time coincident so there is no need for further correction there, but one of the speakers may be further from the listening position than the other. Audiolense will take care of that. There may be the odd reflection from the walls or other, even with a cardioid design like the 8c. Audiolense can fix that too. Finally one can use a house curve, in AL called ā€˜targetā€™, to set the tonal balance one wants. Maybe less important with a speaker like the 8c, but absolutely necessary with my previous speakers for example.

I donā€™t have 8Cā€™s just yet but since I would use Audiolense XO and it can do it, then why not?

How can Dutch and Dutch know the distances from my listening position and walls and ceiling and spacing and other acoustic properties of my room? And everyoneā€™s room?

Using an Earthworks M30 calibrated mic, I can EQ measurements taken from the listening position.

Sure, in theory there should be no time domain corrections required at the listening position with the 8Cā€™s but you would only know by measuring at your listening position/s, in your listening roomā€¦

Donā€™t get me wrong - these are state of the artā€¦ but they cannot possibly perform the same in every room on the planetā€¦ itā€™s the reason D&D recommend everyone take measurements!

But they would be right up there with speakers that come closest to being able to.

You enter the distance from the back and side walls in the 8Cā€™s UX. It utilizes that data in its dsp calculations. It also has an integration with REW built in, so you can take measurements from your computer/mic, correct as desired and download into the integrated parametric filters accessible also from the UX. So if you have positioned the speakers properly from your listening position, the time delay should be non existent or very negligible and the REW process should correct most/all room issues (and of course you can add a room curve in REW). Of course this is not to say you wonā€™t get benefit from Audiolense XO and the beauty is you can try and see what you think whether you apply on top of REW corrections or as the sole correctionsā€¦ Have fun with them. They are awesome speakers.

Noted and this is exactly why I wrote:

ā€œSure, in theory there should be no time domain corrections required at the listening position with the 8Cā€™s but you would only know by measuring at your listening position/s, in your listening roomā€¦ā€

Think of it as doing verification :slight_smile: always a good idea with room EQ.

Agreed, as I wrote:

1. these are state of the artā€¦

2. they cannot possibly perform the same in every room on the planetā€¦ but they would be right up there with speakers that come closest to being able to.

Anyway, my initial questions were only directed to @ogs - I wasnā€™t questioning how current users use EQ.

Thanks ogs for your replies.
