Has anyone here ever built your own KEF KUBE 107, or used the kit? Since it’s extremely rare. I once found it but couldn’t afford, cost is about 600 USD. Anyone has its schematics, pcb layout, part lists, could you please provide us? I’ve already owned a KUBE 104/2. Its power supply is 220V version, part no. SP2123. If I built the KUBE 107, can I use it with my 104/2 Kube’s power supply?

That is exactly what I am doing. I am producing clones of the KUBE 200 from KEF white papers, and also making a 107/2 by applying the 107/2 Bass Extension Correction on a KUBE 200. 7 resistors per side. A KUBE 200 can be turned into a KUBE 107/2, but will retain the KUBE 200 LF and HF Contour.

HI there.

I have been a KEF fan for over 40 years starting with Calindas. After a few years of KEF 104/2 ( I also happen to be moderator on the KEF 104/2 Owner group on FB) and missing a few deals on 107/2s, I finally ended buying a good set of 107/2 this summer. After 16 hours of undoing what previous tech did to the speakers (including finding shims stuck on the voice-coil after a refoam job), they are now finally clean. Sadly, they didn't come with the KUBE 107/2, and when I found them for sale, they are at outrageous prices. High prices driven by way more demand than offer, plus a...

Insane. 32 hours to 3D print a 2"x6"x 7-7/8" box with 1/8" walls.
That will do until I can find a source for cheap aluminum extrusion, in small quantities. Not yet willing to purchase 21ft of it... ;-)

I understand the need for some people to have complete units. Which is why I will most likely ask some tech savior members of this group if they want to do the assembly for others. Unless I can find locally a Indian or Chinese techie working for a lower wage than the usual snobie audiophile rate ;-)
BTW I 3D printed a fascia to test fitment and it is perfect. I even improved over the original design so that the fascia lines up perfectly on both X and Y axis by integrating a lip.
Final casing and fascia shall be CNC machined aluminum if I can manage to group a production for at least 20...

I am very advanced in the process. I will offer kits for people to solder themselves.

You can also buy a cheaper KUBE 200 and swap 17 resistors in the Bass Extension Correction section of the PCB and (almost) end up with KUBE 107/2
