Aging Dynaudio AIR-15 DSP Speakers and repetitive repairs: Convert to external active or buy new L-C-R's?

[Randyman...]

I'm keeping them - but have not ventured into retrofitting them yet. The KH150's are doing the trick, and I've had a lot on my plate But hopefully, the drumming/studio itch will come back in spades (this has been lacking on my end the past few years ), and I'll have a great reason to get around to addressing the AIR's...

Be sure to post here when you come round to it. I hope to find a way to get a long life out of the AIRs one way or another as well... It is a bit discouraging to read that the PSU's might not last even after repair.

Don't know if these are old news to you but I found a page with schematics and PCB layouts for the AIR series:

TC Electronic | Air series | Techserver

The link even includes downloads for calibration and test software.

Hello, I did a passive crossover for the AIR15 in the case someone is interested here's the thread on diyaudio:

Dynaudio AIR15 Passive crossover design

Hey diyAudio people, Just want to share my experience of these last few days, in designing of a passive crossover for the Dynaudio AIR15 studio monitors. In the past I did a few builts using Hypex fusion amp DSP and this is my first passive xover design. I grabbed 9 AIR 15 for a very low...

Whoa! This is very exciting, Thanks for sharing! Looking forward to hear your conclusions about how they compare to the originals.

I am also interested how would one go about modifying the design for AIR12 and AIR6 and AIR BASE 12's. So perhaps should be looking into how to design crossovers in general. If you would have any pointers for where to begin, I would be grateful.

I do have some background in electronics, but haven't done crossover or speaker design. Will start from looking at VituixCAD documentation.

I have an Atmos rig with AIRs in the works, currently have it at 7.1 with AIR15's and AIR12's and BASE12's. Will mount 4 * AIR6's in the heights. I do like the speakers and the DSP, but am looking to future proof the system and if a passive conversion works, that could be cool.

Hey juni, thank you for your interest !
In a professional facility I would go Hypex FA all the way (I use the for my monitors, with room correction etc and it's super easy) but it would cost around > 500€/speaker if you want headroom. You can build a decent passive crossover for around just 50€/speaker + amplifiers (many OEM Hypex UCD boards for cheap around these days)....
For your AIR12 you'll surely have to change my design, but all these drivers have quite a linear FR response so it wont be that hard i think...
keep you update on the diyaudio thread...
cheers!
