Yep, I've been enjoying them too.

Quick question Steve , do I need the WAVE10 board for the Najda xover? Thanks

Thanks Steve

I have a WAVE10 board in my DIY DDDAC and I use my apple laptop as my streaming device. My DAC obviously has an analogue out, and it is at this point that I don't know how are digital crossover works maybe its best I wait until I actually tackle the active project in a couple of months .
It's just that I've got an opportunity to pick up a wave10 board for £50 so I wasn't sure whether I should pick it up for that or not

Time for a little update.
I've been chopping wood again - this time some stands for the mid horns - with the JBL 2482 alnico mag compression drivers they weight 25kgs each and so some support is needed. 21mm Birch ply to the rescue.
The change around has moved the tweeters to make way for the mids - the tweeters 'only' do the 'snow' above 12K and it means the mids can go in line again.



Sound is very similar to the old room - bass is still different, but I'm liking that.
It amazes me how well the horns work in close proximity to the sloping walls - they are not fussed at all. The walls, floor etc all add a bit to the horn loading.
There's no neg reflection issues.
I've not time aligned it yet but still liked it on a brief listening test.
What to do with the Lazy Ribbon tweeters though? Tomorrow I will try them at the same height as the upper horns (smallest) both inside and outside and see what that does.

I also added some wire mesh over the tapped horn mouths as our boy cat liked to go in them. As they taper and fold back (horizontally now) on themselves there was a risk he could get stuck - don't want to be cutting up a tapped horn with a cat in it!
I put some silicone sealant runs around and on the mesh and it takes all ringing / resonance out of it.

Gonna be interesting tomorrow to try it - That's Keith's Najda in there BTW under test - third shelf up. Waiting for the front panel to come back from the CNC machinist...

Pleased it's working well for you Steve.
I'have it in my sights to go down the active route in the next few months or so. I only recently realised the Nadja had an inbuilt DAC, I currently use a DIY dddac www.diyaudio.com/forums/digital-line-level/224108-nos-192-24-dac-pcm1794-waveio-usb-input.html
That I have probably spent well over a grand on building and upgrading, it's actually sprawled over my work bench as we speeak, how would you rate the level of performance of the inbuilt Nadja DAC, any insight would be helpful.
Thanks

Those horns Steve!! :swoon:

Thanks guys.
If you are passing you're welcome to pop in and listen.
Last night I ran it without the 'snow' and you def need it.
I put the tweeters either outer side of the upper horns.
They add the required fizz and good lateral sense. The Raals are very subtle and integrate easily.
I then aligned the upper three channels and all is sweet.
I've found an enduring set up for this room now.
I like the bass very much but may have another go at the very deepest registers as it is not quite the same as was at the old place. The low and mid low is if anything better.
It probably less measuring mic work and more listening and tweaking the room correction points until I get the sound on certain bass notes that I am used to / like.
Fairly quick to do with Najda;)

I only have a couple of correction points, that's how well the tapped horns work lying down, firing mouth up.

I spent some more time measuring anyway:)
Went for a nice flat response 20Hz to 100Hz,
BORING! Sounds contrived somehow.
Reverted back and just played around with the frequencies I felt needed bringing to the fore.
Don't ever try correction on the mid and upper freqs etc. It does not work IMO. Mid bass ok some but deep bass room correction is where its at.
After I while I was able to get the kind of sound I wanted on those all important bass notes without any contrivedness (is that a word?).
Still got the tweeters to perfectly time align so the measuring mic is still needed.

Just re-looking at possible 5v supplies for WaveIO.
I remembered the tentlabs one you mentioned Martin.
Only prob is that WaveIO needs continuous 500mA. Non negotiable as the creator insists!
The tentlabs seems to be for flea powered applications at 80mA!
Or have I read it wrong?
