DEQX Premate 8 digital active crossover / DSP

Thank you for your effort Keith !
Any impression of the sound ?
sinds you have been there I am bit curious

The sound was pretty incredible actually. Quite a few guys I spoke to at the show was impressed by how clear it was. Especially when you take a closer look at the speakers. You can see that it looked like it was slapped together in someone's garage, the joints were not sanded down and the finish was canned spray paint.

I was able to get some details on how they measured and DSP'ed their speakers at the show. They asked me how I did mine - I said "quasi anechoic at the top, then average multiple measurements to get the listening window, EQ the listening window to flat. Then put the speakers in situ and EQ the bass only, apply a gentle tilt to the upper frequencies to taste". They nodded and said "yes we used to do all that. But today we just put the speaker in situ, mic at the listening position, and corrected the whole thing. We used a window of 50ms". I raised my eyebrows. "50ms? That's effectively no windowing!". Kim smiled and said "that's right. We don't recommend that you do that, but it must have been dumb luck and it sounds good. I don't know why it sounds so good but it does". I asked whether they looked at their energy-time curve to see what reflections they are inappropriately correcting. Kim said "I could have done that. But if it sounds good, there is no need to change".

Choice of the 50ms window seems to be only intending to capture response down to 20 Hz audible limit.

Funny, that is exactly my experience with my first setup, which has been running for a while now without any adjustments. Indeed, I just measured each driver at a strange 160 mm stand as Alan described and then between the speakers.
It immediately sounded better than my old setup that I've been working on for years.
I will still take separate measurements with REW to look at the room response and also experiment with different filter slopes and the like.
but so far I haven't gotten around to it because I enjoy listening to the music. So it can only get better ;-)
 
I'm having some issues with the DEQX.

I'm trying to do a new calibration. As I go to chirp the drivers it doesn't do anything and says "Xover cloud not yet ready".
Has anyone experienced the same thing? Sounds like it's an issue on DEQX's side?
 
Try again later, maybe their cloud service is undergoing maintenance; they're on the other side of the world so it's currently afternoon over there. (8:30 PM CST here)

Make sure you have the latest software version, you probably do but see https://www.deqx.com/support/

That could be the case, I hope it's fixed soon. I've got the latest drivers, I've made a ticket as well. Hoping for a quick solution.
 
I’m at Work at the moment so I won’t be able until the evening .
(Amsterdam time )
But I wil do so , no problem ;-)

The latest One !
The one that was in the message from Alan
Don’t known wich ecxacly in Numbers I must dive further in than ,1,37 i thought !
 
Thinking the issue might be cookies in my browser I tried to clear them, no luck.
I tried a different browser, nothing.

Maybe the issue is my computer? So I tried my tablet instead. Success. Everything works as intended.
My theory is that the new Windows update, 24H2, has messed something up entirely in regards to how the computer accesses the network.

I'm happy it works now.
