Would you share the final exterior dimensions, volume and tuning of your enclosure?
What type of components did you use? In particular the 2 ohm inductor, did you use a laminated steel or?
I have a few of the Q100 drivers bought way back before Kef stopped DIYer's. I got inspired by AJinfla's idea of using the Q100 sealed and integrating it with a plate amp to cover the bottom end. Sadly until now haven't had the time to finish.

Tuning 55-50hz it depends on room.
You probably think on 2mH?! 000-1711 2.000mH Jantzen Air Core Wire Coil AWG26, 0.4mm diameter wire | Hifi Collective
Don't go crazy on capacitors any WIMA mkt or mks is good. There is no difference any way.
For resistors regular ceramic is fine. CB5JB18R0 Stackpole Electronics Inc | Resistors | DigiKey

Jokerbre, did you make the enclosure or purchase it from a vendor. If you purchased the enclosure, would you please share with us where you found it?
I'm asking because I'd like to follow your lead and improve my q100s with a more robust--and sealed--enclosure but I lack access to woodworking tools. Thanks in advance for your help!

This is just amazing work. About to start a thread and project using this driver. I would like build an open baffle using the Mazanita GRS 18" driver, possible 2 in parallel, and crossover to the Q100 drivers. Any advice you can give?
Without a full set of measurements on baffle both drivers I can't suggest anything specific as it would be frivolous on my part.
Already some years ago there was a project from Germany that has won a DIY contest using the driver from the Q100
Here a picture:
The guy has chosen to run the stuff with miniDSP and 6 amplifiers.
One of the remarkable things i have read is that there was the finding that with the active crossover there is a chance for a slight improvement with a delay between the cone driver and the tweeter of the coax - there is no good chance to get this with a passive crossover.
KEF made a lot of research for the crossover of the KEF Blade - they stay with acoustical LR12 and correction RLC for the resonance of the tweeter.
I have made some listening tests with woofer + KEF R300 coaxial driver unit with 2 X miniDSP 2 X 4 HD and the best soundstage is achieved with LR 2 and not as usual for many other designs with LR 4.

Jokerbre,
First of all very impressive work on Q100 upgrade. I'm trying to figure out required components for you crossover design but having some issues with finding the exact match for following:
Do you think you could point me in the right direction, please? Thanks.

- C6 26.2uF
[*]R1 2.8 Ohm
[*]R3 6.80 Ohm
[*]R6 1.80 Ohm
[*]L3 0.310mH
Do you think you could point me in the right direction, please? Thanks.
L3 is Jantzen air coil. Catalog number 000-1629

C6 could be 18uF in parallel with 8.2uF - but lets wait for Jokerbre to respond. My guess is that he wouldn't use these values if he didn't needed those exact values.

If it's complicated for you, you can combine 10+10+6.8uF, it's not a problem a small change in value. You also combine resistor values. This project served me to get a better sound than the LS50 for less money. And I succeeded in that. Can there be a simpler and simple crossover? Yes, of course it can be, but my logic is always to do the best possible without paying attention to the number of components, but only to measurement and sound. When I achieve that, I can slowly reduce the number of components because I have a starting point.
