Open Baffle _DAC8PRO

[vitalicca]

After a while I managed to finish this set of Open Baffle with AE and Beyma TPL200H speakers.
With the help of Mitch (whom I thank enormously for his patience ) I managed to learn a little Audiolense. I think after 30 years in this hobby, it was the biggest revelation for me.
How versatile and accurate this tool can be! And if you're lucky enough to get the settings right, the sound is exceptional.
Now I come up with a beginner question
This filter sounds amazingly good for my ears.
But is it OK what happens here where it is marked with an arrow at 60 Hz ... at 200Hz?
I tried various settings, but I can't get rid of this 60Hz crash.
Thanks so much for any advice

Those speakers look great. Is there more information about them somewhere?

A short information I posted on diyaudio in the Open Baffle Gallery and that's about it. Broadly speaking, the frame is made of a 15mm stainless steel plate in the middle, and a 10mm plastic and 10mm aluminum plate on the side. The speakers are attached to the frame by magnets, which have a thread. The speakers are 2 x AE Dipole15-16 (NCore400), AE TD8M (GaN 200W), Beyma 200TPL (GaN 200W). I can say that I am in love with this Beyma tweeter, it sounds very natural, without any harshness. In my case, I removed the back cover.

I’m very impressed. Can you tell me why you went with the Beyma 200 rather than the 150? (I’m not sure what the differences are.). I know that lots of people really like the Beymas in OB.

WOW...how meticulous your assembly must have been! They look flawless... I am assuming you did CAD drawings, and then CNC'd them, correct?

Could the 60hz, and 200hz dips be a room null?

In "Correction Procedure Designer" I increased to 12 dB "max correction boost". Now it looks better, but maybe I'm wrong. But the bass became even more beautiful. Why did I choose TPL200? At the beginning of the pandemic, a French store reduced it to 50% and ... I couldn't resist Now I think I would buy them and at a full price, they sound so good. At first I cut them to 2500 Hz. But still "playing" with the settings, I found that it sounds really good and cut to 1200Hz. Now that's how I listen to them Yes, everything was designed in CAD and then machined in CNC. They cost something but I thought they would be my last speakers

I agree… awsome speakers. The 60 dB dip has to be a cancellation. Wall behind the speakers, maybe. For what it’s worth I don’t hesitate to Apple 12 dB correction boost if it makes a signifikant difference. I have been as high as 18 dB. Critical listening will tell you whether it is for better or worse.

When we built my speakers we also looked at the speakers as being my end game speakers...now I am swapping out drivers. LOL
