Excellent teacher! Knows what he is doing for sure! Plus, shares important 'tribal knowledge' one only gains from experience! I recommend his videos!
Nice job - I just brought mine out of storage after 15 years and they sound great. Woofers all see good so far but I know I will need to do this restore at some point. Thank for all of your expertise on this model.
As BEERLIGHTBROKER said, your videos are very informatives and full of your experience, I don´t know how the technicians and people that works repairing speakers aren´t seeing your videos. I thank you very much for share all your knowledge and experience here, I´m electronic technician with 28 years over this job and an audio enthusiastic, audiophile for allmost all my life and I know very well when a person is an expert. You´re a great expert my friend.
Thanks more on the way
I'm a speaker repairer and the KEF 104 is one of the bigger cabinet repair jobs that can be done. I'm in New Zealand, so we don't get the really big and expensive cabinet speakers. Top of the line items are out of the range of the average person, so they don't get abused.
Beautiful work. Bringing kef reference back to life. Thanks for sharing!
Absolutely fantastic quality job. High respect to you.
Great video!
Shame that the KEF folks were quite stupid to install speakers with foam surrounds instead of rubber inside the cabinet.
Later 104/2 models actually had rubber surrounds but the foam donuts remained...then in the Reference One etc. they did the big stupid again, and returned to foam surrounds. Sometimes you just don't get it.
A very nice restoration indeed
Another awesome informative video. Thank you.
Excellent video. I appreciate your obsession for the the little details of the reconing
I absolutely love the 104.2's.. Wonder if my pair need this repair
I had the current KEF flagship 207 (we repaired)sitting next to a pair of 104/2 (we restored) and the 40+ year old 104's smoked the 207's @ $20.000 a pair We will Restore your older KEF's 101,103/2,104/2, 107/2. 105's texasound@gmail.com 512-769-9750. Rock On!
@@texasound1 Amazing.. I hope I will never have to get rid of my pair.. even though my spouse eagerly has nudged me to do so for more than 10 years already.
Thx for uploading!
Guys a beast with speaker repair!
I recently did the same repair on my KEF 103.5's but unfortunately a redo is in-order. I did a sub woofer test and found distortion around 20-35 hz. I believe there is either some debris left or the spacing was off in the voice coil. Plan to do a video and post on my second attempt. Here's hoping!
Have a pair of KEF 104/2 and one speaker doesn't work. It won't 'Tone' for continuity. Will end up opening it up and doing a visual. Wondering if I test the crossover plus(+) minus(-), if it tones out then there is an 'Open' short somewhere. If the crossover doesn't 'Tone', then that's should be where the issue lies. Would I be correct? Anyone here reading this, any input is very much appreciated.

Question. Can just the top woofer be taken out and repaired without removing the bottom woofer on the Kef 104/2? Thanks.
⭐️ this is SO helpful - can’t say thanks enough for taking the time to share your knowledge and experience 😎 ⭐️ 👍 What glue are you using please ?
Great video! I just got a pair at an estate sale, and would like to tackle this repair myself, but I have some questions: Where can I get the foam replacements parts? Where can I get the correct capacitors? What is the correct glue to use? Thanks!
any thoughts on how i can get a magnetic coil repaired in my sansui speakers
What kind of solvent would you recommend for the donuts? I’ve tried scraping lightly but I am worried I’ll damage the cone if I try to get the remaining residu out. I am not a fan of solvents myself either but I think an exception is warranted here.
What do you use as the shims? what kinda plastic?
Does anyone know if the rod in the 104.2 is interchangeable with the 105.3??
Great informative video, but video quality could be better, very dark and grainy
Any thoughts as to why the KEF engineers used the rod between the two woofers? My 103.3 only has one 8" woofer, but it also has a rod, bolted to the bottom panel.
The whole design philosophy of the opposed reverse-phase woofers is that all mechanical vibrations and distortions are balanced out, so by tying the two frames together directly by an aluminum (higher internal damping than other metals) rod, those balancing forces between drivers are rigidly coupled, while the drivers and those forces and vibrations are isolated from the cabinet by the driver mount grommets. This keeps those forces from acting on the cabinet, and in theory reduces audible resonances. In the 103.3, it appears they used the tie-rod to try to brace the single woofer against an internal baffle, to increase rigidity.
What is the purpose of the rod that connects the woofers together? I can't think of any advantage it would -have. Thanks for the video.
Read the brochure for the 104/2 regarding the coupled cavity. In essence the design is to provide more bass response while minimizing distortion. Does it really work? I don't know, but I love the sound of my 104/2's. kef.com/uploads/files/en/museum_pdf/80s/Reference_Series_Model_104_2_r.pdf
If I wanted to get a set of 104/2 s restored by you how would I go about it?
Hi Sorry I missed this. One of the problems with doing these video's is that I can't keep up with all the questions and emails. We don't make any money doing this and it takes a lot of time. Please call us for speaker restoration at 512-769-9750 Thank You Music is the very best thing that the human race has ever come up with. Rock ON!
whats the purpose of the donut rubber?
To keep anything from getting into the magnetic gap
A shame that KEF built in so much crap - but excellent video.
What are talking about? These are very good sounding and good quality.
@@derfskittlers6125 Obviously, you have no awareness of quality.
You haven't got a clue!
Show Bags - Over rated, Over priced and full of shit.
The design of these is fundamentally flawed in so many ways, especially that stupid 'doughnut' foam. When it degrades and disintegrates it falls into the gap.
KEF cheaped out using a pressed sheet metal basket on these woofers that perhaps need the coupling rod, and hence the need for that stupid inner foam.... so much for the F (foundry) in the KEF name, eh.
I seriously question the replacement of electrolytic based on maintaining the 'original sound'. MKP are far superior in every way.
What kind of solvent would you recommend for the donuts? I’ve tried scraping lightly but I am worried I’ll damage the cone if I try to get the remaining residu out. I am not a fan of solvents myself either but I think an exception is warranted here.
Toluene but he is using alcohol.
