KEF 105.1 xover

[rx7rotary]

Hi guys,

I really need a xover for kef 105.1, if anyone finds a way to source one, and has one to sell or whatever , please let me know. I am trying to restore the speakers.

I thought I have the xover but I dont.

Thanks and regards,
mark

Quite easy to find the circuit. Here it is.

A refurbishment thread for this whopper too:
SpeakerTalk :: View topic - Refirbushing Kef 105.1, NEED CROSSOVER SCHEMATIC, etc..

Good luck with it.

Ah, someone posted a picture here of his KEF 105.1 crossver rebuild. Rather nice!

Bet some of those capacitors cost a few bob.

Do you guys still have shillings since changing to newpence?

Thanks for that guys, I have just purchased these speakers recently and been following an ebay uk auction but have missed it yesterday and the original xover went for 85 quid... I almost shot myself for not getting it. Although including the postage it would have cost me around 150 quid or so, so then I worked out that for 150 I could build a decent xover for the mk1s ? What do you think?

Regards
Mark

There is a dedicated Kef owners website (for early models) and it can be Googled by putting "hifiloudspeakers" in the system. Good forum and a lot of material. A man called Colin Royal is an authority in this area, chase him up.

Well worth a visit.....Jonathan

Mate, do you know how would I contact the person that has done this xover?

Thanks

Before you clone this particular board it might be worth looking more closely at the layout. From the photo there are a couple of inductors/coils that look like they are a bit too close to each other and would probably benefit from being "angled" towards each other rather than parallel. That may be a potential issue. I'm not an expert in this area but I believe the problem is called "mutual coupling" or something like that. Check with the 'gurus' though.
