Funny enough I had a premier digital front end after ditching my vinyl rig nearly 2 years ago. I recently sold the digital gear (and the rest of the system) to return to vinyl, and a fresh approach. Digital is okay but it couldn't hold my attention or interest compared to the previous 30+ years with vinyl. For me digital is dead. So glad I kept my vinyl though!!!!

Cheers, Pete.

No problem. Kef are very helpful, superb customer service. Even for a 30 year old speaker system. Sure they will still have some.

Let us know how you get on.

I did a repair on a neighbours 104.2,s about 6 years ago. He had managed to blow up both tweeters. I replaced them with T33 types which were available at the time. He was so pleased that he invited all his mates around to celebrate and promptly blew up one of the new tweeters. That was not the end of the story however. There was also a burnt smell evident. Upon dissasembly it was found that several of the crossover caps had exploded! I replaced them with caps of higher voltage rating. I am aware that the originals are hand selected but I had no choice but to replace them with the values as marked on the remains. One more new tweeter was fitted and all seemed o/k. On listening to them I was aware of their quality. They produced efortless LF down to very low frequencies and midrange was very natural. HF was a little forced for my liking though. It didn,t last long. My neighbour likes to party ang one night I could clearly hear the music from my house which is 5 doors away. Needless to say they were destroyed again. I won,t be offering my services anymore. I hate to see nice speakers abused. Maybe one day I,ll obtain the remains for myself and rebuild them.

Dear Friends,
I have old KEF 104/2.Bass units B200 (SP1256) have destroyed (all four surrounds of bass units rotted).I have founded Monacor Sph 210 as a possible replacement of SP1256.Is it a right choice or are available alternatives ? I would be very obliged for Your recomendations .

Hi, there is a company in England i had found before that rebuilds and recones loudspeakers, they had the machinery to professionally recone the b200 driver. It was a while ago, but think it worked out around £200 plus postage for all 4 drivers. They can also rewind them as well.

Ill have a look and see if i can find them for you.

I also remember a seas driver being mentioned on a forum post as a good replacement for the b200.

Really helpful chap

Sure that was the company i spoke to in reference to my b200 drivers, but as my drivers have the rubber surrounds i did not bother just now.

Do you have the b200 drivers with the foam surrounds and foam inners?

chelg2012 · 8th January 2013, 10:02 AM

Dear Sir,
I've already changed the rotted foam surrounds and inners of my 104/2 by these were bought here KEF 104 2 Speaker Foam Repair Kit incl Donut Dust Caps | eBay
Result of such replacement is dramatically unsatisfactory.Surrounds sent from USA were hard and thick in comparison with original KEF's. As a result-strong degradation of bass input especially in lowest frequences which became very bad quality. Therefore I am looking for a modern bass drivers can replace old KEF B200 (SP1256). Could You help me?

Reference1042 · 8th January 2013, 12:58 PM

Have you emailed or phoned Kef to ask of they can recommend or maybe even supply a suitable replacement for the b200?

I bought a set of replacement (new neodymiums) tweeters a few years back for my 104/2s from Kef direct.
