Hi Folks

Been lurking around and decided to join looks like a very informative site, sadly I only discovered this place after buying a pair of R50's from fleeceBay.

Yes I was the chump who bought the ones with the B&O crossover and a mish mash of drivers
You can read about the bodge here http://baobab-audio.com/index_files/Page321. I was tempted to move them on and plead ignorance, but not my style.

Needless to say the sound was pretty dire, the treble was nasty and harsh, the mid was dull and the bass totally overwhelming in a bad way.

I should have known there would be trouble after looking at the workmanship involved in making the speaker stands, which will be used as kindling come the winter.

Taking the baffle off both units revealed a sorry state of affairs, the coles were blown, the isophon kk10 had been fire cemented into the baffle, one of the dalesford 110 needs refoaming, the wiring from the crossover to the drivers were joined together with insulation tape .

So my idea is to rebuild the R50, out goes the BO crossover and the isophons
Not sure whether to keep the dalesfords or replace with b110 sp1003.
I have the potential to buy a wilmslow r50 crossover plus two coles for £100, I've bought two T27's already and the existing b139's are fine

I'll need to build two new baffles as getting the isophons out was a nightmare that caused damage, I will look at getting the baffles made out of veneered MDF.

Can anyone give advice re the following

Falcon crossovers compared to the Wilmslow offering

vifa D27TG-35-06 be a better choice than a T27

QED 79 strand for all wiring (is this a good choice)

mounting the new crossovers externally due to size or still locate them on the baffle.

Any advice appreciated

Finally thanks to Colin R for his advice and help before I joined the forum.

Thanks Colin, I did speak to Jerry about two weeks ago and he was going to get back to me re pricing' guess he's still v busy with the new site as I've heard nothing yet.

Wilmslow seemed to just want to flog the board and didn't offer a great deal of advice, quite the opposite to Falcon.

Not sure whether this will be read but here goes.

Looks like I am the new owner of these speakers, well cabinets only and pehaps crossovers.

Thought I recognised the pics on that well loved site. They were sold as cabs and crossovers so lets hope the correct crossovers are with them not the B&O ones.

I would like to take some time and get them going, making a few changes along the way. The only real change will be to try a HF1300 instead of the T27. There appears to be many excellent crossovers for the HF1300 and Coles 4001; DM4s and BC1s for example so combine these with the original crossovers and my ears will do the rest.

Collecting tomorrow so fingers crossed. I wonder how many strs oh hands they have been through since owned by Mr Atiopu.

Wish me luck!

Have collected them and will start a thread named Baobab/Cambridge R50s to document my adventures.

Well if you haven't looked yet the infamous R50s are back up and running, with the original baffles too! Take a look at my thread. The more I listen to them the more I like them!

The final T27 was SP1032 with wires on the faceplate, all black or sometimes black and blue in the Kef way. The previous one with clean face was 6340 though that had a variation for selling to other manufacturers.

I was initially trying to get the newer type T27, I have a dead pair and the older ones seemed to be a better fit. As the B139s were the original Racetrack type it was possible that the T27s were the older type. Not sure whether the sound would be much different? I have a pair of Morel CAT 298 Tweeters which are recommended by Falcon and the mounting holes are identical so I might try those at some point. If I can get a pair of the later T27s at a reasonable price I will try them, I also have a slightly later pair of B110s still SP1033s but originally black and a later pair of 139s so may be worth learning how to use a router.
At the moment the bass is a bit loose at times, never sure that is the recording or speaker, any ideas on whether I should add or take away the long haired wool from the bass chamber?

Did you use the original fillings at the right places?
The white cloth stapled behind the B139 isn't there originally.
Perhaps it's better to remove it, might influence the speaker. Prevents it from a full swing.
Succes. TL.
