No name, it's simply a KEF 203.

If you want a provenance try the Caprice II SP3001, B200G, T33, crossover a'la CS3/5.

Not the Ref 103.2 as the pimps on ePay would have everyone believe.

You should be able to get your SP1075 repaired somewhere in Chicago, as that's where I've been informed British KEF T33Mk II (SP1202, SP1191, SP1197, SP1197X) endowed loudspeaker owners get their ferrofluidised duds rebuilt.
You could always replace the SP1075's with paper coned SP1070's out of Celeste III's or IV's a'la the KEF 303.3 SP3002 btw.

I'll ask when I next see a 107mkII or 104-2 owner, however not having vast quantities of T33mkII's stored in my garage our paths don't cross that often.
So I suggest you ask about coil rewinds and network from Van L SpeakerWorks, 5704 North Western Avenue, Chicago, IL 60659, Tel 773 769 0773.

Maybe while we're at it someone could explain what the difference between the 203 and the reference 103.2 is exactly besides cabinet size - the drivers look identical! My pair (of 203s) is type sp3001. The 103.2s sound a lot better.

The 203 will have a crossover similar to that of the Carlton II or III, (a simple photograph or detailed description would enable confirmation), whilst the Ref 103-2 crossover is actually a modified Ref 101 circuit.
If you really like the 103-2 sound, why not find the circuit on this site, take the component values off Steve's schematic and use KEF's tolerances from the Constructor Series designs and make up your own crossover.
You should either hard wire it externally or do it on a largish Veroboard as you probably won't be able to "make-up" a Ref 103-2 circuit by simply substituting values on the existing board.

Laughing Well im back to report,my 8inch-kef-sp1075-is back in working order,thanks to colinR and vanlspeakerworks.com . This shop is a pleasure to visit,while my woofer was being checked John,asked if I wanted to listen to some music on one of his in-house speakers,set up in a church stlyle shaped room.The amp was a integrated jolida,the cd was the same ,I sat down and listened for about one hour and forty five minutes.The sounds that came from the pair [quartet] of speakers were nothing like ive ever heard,[and ive heard many]they are fairly priced and I will purchase them as soon as funds allow.The kef woofer got a break-in,back in its cabinet,this weekend,and alls well.You know,when your stereos running good ,lifes a bit sweeter.
