From memory KEF supplied a kit of parts to the cabinet makers. They were dispatched direct to dealers to reduce costs. The repair woofer came conventional gasket. The spade terminals to help the wood workers. Nice speaker for low price in the day.

fascinating thank you

Very useful. Thx. Just got a pair of kef 101. will check them!

Hey, what wire do you use? And what's the stuff you clean the speakers with ? Many thanks

You had me at "If I can be assed" hahaha!

Power cables have their own tone and balance just like speaker cables and interconnects. So there. You've been told. Now shut up and go away :)

HI Matt, quick question..... why are speakers made from MDF and not HDF? When I rebuilt my Ditton 25's I used HDF Because of a book I had on building speaker cabinets, can't remember the name.

Great video on the repair of speakers which have obviously had some abuse. I have heard a number of LS3/5As over the years and although I have never owned a pair, I am a bit of a fan. Last year I was in the market for a pair of "foot high" speakers as near-field monitors. Although the LS3/5As were at the top of my shopping list, after some auditioning, I bought a pair of ATC SCM7s. I have been doing the HiFi hobby for 50 years now and have somehow always ended up listening to British built speakers. (My absolute favourites are my Lowther horns but they don't fit on my desk-top.) Keep up the good work, Matt.

Hi Matt.. What make/model of Drillpress do you use?

4 x 2 foot ply mdf sandwich. I used buckets of water to hold them together whilst the glue set. Even so slightly bowed which looks good. Wicks stock. Terry at Loricraft Audio lent me his router and workshop to do the holes. I still talk with him. We both love Quad ESL. Loricraft is now Spendor SME.

I found the 902-472 tweeter you like at a good price at CPC Farnell. 902-527 8 inch bass unit looks interesting. I have used one of that make 15 inch bass units with Eminence 12 Lta. The tweeter DT74/8 which was about efficient enough. 4 x 8 foot baffles. Quad 33/303 To use a better tweeter would have to be active. Considerable bass equalization. I had some BC1s around to remind me of correct sound. The tweeter did more than I imagined. Image width especially. First order cross. First order 15 inch. Eminence no filter. The only time I succeeded with a simple design. I had some Dynaco A25 that suggested the idea.

Great job, yet again, many thanks

Q. Does having a larger centre cap in the bass and midrange help with off axis response?

Nicely done once again. Regarding the mids.. Are those actually banana plug jacks .,? or spring push button? My pro sound JBL drivers with push button terminals for connection ., I simply use gold plated, speaker wire PINS, not banana plugs. Looks much better inside the speaker cabinet than up bunch of bare wire or a dirty tinned solder wire.

Крутая работа, тоже такие хочу сделать 👍👍👍👍👍👍👍👍

Nice work sir. Interesting videos. I could do with a knowledgeable person such as yourself to give my JBL 112's an overhaul...?

French polisher/antique restorer here. We always use stripper for something like this that has been poly lacquered as sanding will give a patchy finish. If stripped and cleaned down well with a solvent after, you would get a uniform base to sand and finishing will colour up uniformly with minimal ghosting. The veneer on the top appears to be ash.

Try a print free brown paper bag and a fairly hot iron on the water stain before sanding.

Yeah, those mini banana plug connectors on ATC drivers are really poor, given the quality of the drivers. I think it's a daft concession to professional use, so they can be swapped out easily. Measurements are great. Interested to know your impressions of the music they make. Guess what, it's Wales and it's raining.....probably a bit warmer where you are....

When I have had issues with sun fading, I've used a darker oil on the veneer.

Nice job. Are you back on the coffee

Evening Matt 👍👍

If the fuse is to give cable protection (!) , then what is protecting the device?

You talk about voltage drop across the length of the power cable as being a factor (~1:25), but with average copper that can't logically be a factor. Perhaps stick with the screening idea and compare screened 2.5mm Vs screened 0.5mm Vs unscreened 0.5mm

That looks like a B&W DM4 .

I think the Omar rep was Charles Thompson who because of back pain was a bit miserable. That changed when describing how the speakers came about. The Omar version very different. Or so it seemed. Omar CR251 Dalesford and Peerless were very good and Omar Goring a Minimax type speaker. I went to the factory once. Quite impressive. I believe the family once made the famous Omar caravan?

Cozy and neat workshop you have there Matt. Thank you for sharing.

Would a sanding sealer help with the blothes? It helps when I use polyurethane on hardwood floors. Just asking because I don't know regarding wax. Great work by the way. They're beautiful!

A tip for removing wax - use a cabinet maker’s scraper (card scraper) to get most of it off before sanding.

They look great Matt. Well done!

I'm wondering if it is possible to build a standalone super-tweeter using these piezo tweeters with minimal disruption to the original x-over network of existing speaker. I'm addicted to the airy high on the DM4 and wish to add some air into my KEF 104 as well 😂

Wow - such a seemingly innocuous thing and yet it made a crucial difference!

Those scan d2608 tweeters are really good tweeters. Troels loves them too

Good sounding speakers👍

I chose a pair those Dynatrons to go on the end of a Philips AG9016 but they were terrible speakers. God knows why they didn't put decent driver's and bracing in those cabinets. Putting the ABR on the back is a great idea. Can't wait to see the outcome and hope that it works for you!

I'm glad you went with felt on the baffles - I think it looks fantastic and the sonic benefits make it the clear winner. Great work again!

I have been ill for six weeks now with every cold and cough going through my daughter's school.

Great work - they look fantastic and bet they sound great too!

Absolutely amazing work AGAIN! I would love you to work on my Kef 104ab crossover. Both measure identically, drivers and cabinets are good, but there is so called bbc dip 1.5-6k. It's minor, but after equing it I like them more + components are old.

Very Nice ,congratulations .

Its really like anything else. I know a guy who owns an expensive fishing boat that he only takes out about three times per year. For me, Id just rent the boat, and split the cost with friends. I rebuilt some budget RCA floor speakers as a way to learn more about how to do it. I figured, why not start with them, I won't be out much money if I mess them up. Its a hobby thing, not a money maker. As it turned out, beginners luck had it so that they now sound amazing. Not audiophile grade, but still nice and balanced, and much better than the original drivers and crossovers.

Hi Matt 👍👍

Another great job, shame we can’t here the project when completed, just to get a sense of how they sound

Well done!

You know that you can tame the tweeter top end whithout needing a coil in series with it, but rather with a cap in \\ with it.

What's that liquid you put on the rubber surrounds again? It was for cars if I remember rightly. Chemical Guys VRP?

Using the Kef B200 is a compromise. It’s a good driver, but the original Spendor bass/mid. is superior. The best use of the B200 is in the Tangent TM1. I have compared my BC1s with the TM1s. The bass end is better on the Tangent. The midrange and top is better on the Spendors. If you live with the Tangents for a week or so, the BC1s won’t be missed. You adjust to the Tangents balance very easily. I could live with either pair of speakers...

hows it going nice build how did you build the cross overs ?

I had many chats with Mr Hughes about how things work. I knew Paul.Messenger who worked with him.

Hi Matt. As always, an exceptionally interesting video and great learning experience. Thank you. ❤
