Recapping KEF reference series 105

My crossovers are not adjustable. Did you add that?

"Mine has 2 crossovers. One inside the mid and the other in the bass box. There’s another board for the knob which I wonder if I can disconnect."

I'm just guessing, in case you could 'fix/adjust' your speakers before upgrading parts.

 Is it possible you do not have the KUBE 200?

this one is sold, but it shows what it looks like.

excerpt:

"Our test speakers were furnished with an active external equalizer, the KEF Kube 200, designed for use with the Model 105/3’s.

The Kube 200 should be installed in a low-level signal path such as a tape-recording loop or between a preamplifier and power amplifier. Pushbuttons on its panel can replace the tape-monitoring function (there are tape-in/out jacks on its rear apron) and bypass its equalizing circuits. It has separate low- and high-frequency control knobs, with center detents, and a small, separate power supply.

The Kube 200 is 6 inches wide, 8-1/2 inches deep, and 2-1/2 inches high. Price: KEF 105/3 speakers, $3,500 a pair; Kube 200 equalizer, $390."

IF you proceed:

Normally, each part, capacitors/resistors has identifying marks, and you can get new parts with those values (i.e. +/- 10%, or 'better' i.e. tighter tolerances.

My friend bought a device to measure his crossover parts, found a few parts that were bad.

I can ask him which device he bought if you want.

Mine also have 2 crossovers and the one by the knob. That knob connects directly to the speaker connector so they add resistance. Very strange. Doesn’t make sense to me. 
how did you add a picture?
