Thank you Larry for this excellent video. Made my 104/2 restoration/modifications so much easier. I've actually bypassed the Woofer section of the Crossover.I am running a miniDSP with the proper KUBE EQ direct into the refoamed (Donuts only) Cavity Coupled 8" Woofers. I added a second set of Binding Posts for just the two Woofers and replaced the thin crappy Speaker Wires with some 16AWG Speaker wire. About to replace the Ferrofluid on the Tweeter's today. I'll let you know how that goes.
@@larrysmith7168 Tweeter Ferrofluid was a success. One of the Tweeters level was way down. Just had to remove the screws and re-align it to with the front baffle and success ! Thanks once again for a great Video.
Hi Larry, my Kef 104/2 doesn't seem to have audible or same output for 100 hz in comparison to the other low tones, does this mean it is broken or is this expected?
I remember listening to these back in the early 80’s at a local Hi-Fi shop. If I recall correctly they came with a small black box, the Kef Cube? an electronic device with a dial on it, it’s purpose unclear.
I can't imagine the rod not having a purpose that is beneficial to the sound in some way and can't imagine after going through all the trouble that I did, not returning it to it's original condition. But I suppose you could do as you suggest and may never hear a difference.
Some people change out the tweeter for another brand but I removed the dried up fluid inside the tweeter and added some new fluid and made them sound so much better. Fyi. I bought these used many years ago. Finding the fluid was a little difficult but I think eventually I got from the manufacturer for free.
My customer supplied the parts. I do seem to think Madison and ordered as a "kit". It's been years but I recall a couple were unable to be matched but the values were achieved by combining 2 caps together to reach the value of the one being replaced.
@@larrysmith7168 Blimey that was a quick reply to an old vid but thankyou ! I've noticed that on some there was a foam outer surround, some a butyl, got confused over these B200's. Thanks again.
FWIW, KEF tried to make the speaker 4ohm purely resistive using conjugate loading. There was also an active bass extension box called the KUBE.
Thank you for documenting the removal of the bottom part, I almost went the way of another TH-camr and destroyed it to make my own. Great work 👍🏾🤘🏾👌🏾
Awesome. Glad I could help. Best of luck!
Very good job . Thank you and best regards.
Cheers.
Those feet on the bottom plate are an M6 thread.
Great tip on removing the base boards, thank you
I get lucky sometimes. lol
Too bad you didnt show us the ferrofluid document... :-) I wouldnt have found it boring... 🙂
Damn. The whole reason I watched is to see the ferro fluid changed.
Ouch. So sorry. I looked through outtakes and I guess I simply didn't film that part. My bad. I will keep that in mind the next time I make a video.

One speaker sounds different than the other? I would suspect the crossover may be the issue. Might be a bad capacitor.
What a nightmare!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I'm working on KEF 105/3's now. Twice the nightmare... I mean, fun.
Larry whay you didnt let him play ????

The KEF Kube is a treble and bass control meant to be used as a tone control. Without the Kube, a Schiit Audio LOKI + will easily fill that role
can that center metal post be removed all together and a standard dust cap on woofers.............just askin

How to connect the speaker wire?

Can you tell me where I can buy the fluid? Thanks. Sam
@@samvan7787 I'm about to service T33 and bought ferrofluid form Simplyspeakers $12 per tweeter kits with fluid, blotting paper etc
Where did you get the caps from...I thought of Madison and how hard was matching the values?
My customer supplied the parts. I do seem to think Madison and ordered as a "kit". It's been years but I recall a couple were unable to be matched but the values were achieved by combining 2 caps together to reach the value of the
one being replaced.
Trying to find caps for my Kefs any assistance would be great.
Hi Mike! I own the speakers in Larry's video. The caps were purchased as a kit from Falcon Acoustics in England. The caps brand is Alcap.
@@MrBillyNaegeledude how can I get falcons email or address help me out bru. Thanks
