Hallo,
the restore of the kef 105 (mk1) has been performed in full respect of the original project without the application of any circuital variations.
The restore consists (for both the couple):
1. application by a specialized laboratory of the “kit” of capacitors provided by “falcon acustics”, and replacement of the connectors and wires

..here the xover before and after.

2. check of every single driver with the production of the graphics of the impedance/frequency /phase.
This the graphic of two B300 woofers for example….

then reassembly
at the cabinet of the first couple I provide the application of an adhesive film (3M production) by a photo typolithograph laboratory.

the cabinet of second couple is painted with epoxy paint

The 105 mk1 don’t “shines” for the “punch” on low frequency or excels for the purity on high frequency but have a great dynamic equilibrium and short listening fatigue. I really love it.

Good evening,
I see in your "picture" that you love too these "historical" loudspeakers......
Lot of work, but I've done with pleasure to return a new youth to some old british ladies.

Surely there are better places to do the work than in the back of a van on Westminster bridge?
