Hello people out there.
I own a pair of B-200's sp1054 which i want to use in a two-way system, combined with a Philips tweeter and cross-overs from Chorales.
I can hear you think "what a combination" Rolling Eyes .
Let me explain: i used the b-200's in a self build Baily's TL.system, used them for years. I got a pair of heavily damaged Chorales one day, i wanted to use the T-27 in my bailys but to my surpise they contained a Philips tweeter. 25 mm dome, nearly same size as the T27, not really bad at all.
The b200's from the Chorales went to my brother who's son blew them up trying to play DJ. Sad
So all is left is the combination i mentioned above.

Now to my question; what internal dimensions should a closed cabinet for the B-200's have (ought to be)??
I was thinking about 30 liters for volume but i am not sure.
Please give me some suggestions.

The KEF datasheet issue 0677 for the SP1054 states, totally enclosed box 20-25 litres, reflex 40-50 litres Cool .

Thank you Colin, i already looked at Home page hifiloudspeakers.info(Terry's website isn't it?)
but the links to the datasheets didn't/don't work. So Terry, if you read this please take a look.
I'll try and see if i can find something about a KefKit in which the B-200's are used. I mean to know that the sp1054 was never sold for homeconstructors, please let me know if i'm wrong. Thanks for so far, i'll let you know about the progress

To my knowledge, the SP1054 was only used on the Calinda. So, I would think the perfect cabinet for that would be a 50lt PR one combined with a B139PR.

By KEF, but it was used in one of the Celef Studio Professional Monitors as a midrange unit with ATC bass and treble units.

Apart from stuffed boxes the SP1054 unlike the other B200 varients (as I've tried them) is good in a ~4' folded tapered horn Cool .

I made a terrible mistake, i hadn't seen them for years, and i recently found out that it is a pair of SP1039 Embarassed
I don't know how i got this false memory Shocked
Thanks anyway folks. Won't be until summer when i am able to work on it so i have some time left for research.

That's easy then, the 1039 was one of the best, if not the best B200 for lack of midrange colouration, short coil in a long magnet gap for low distortion and used in the original 103 and 104 +aB so for closed box use the internal volume of the original 103 - which unfortunately seems to have the wrong info in the relevant Kef history page!

Found some info here, since i highly judge Colin's knowledge i believe that the measurements he mentioned will be the right ones.

You're right about that, i owned a pair of sp1014 before and they sounded, as we say in the netherlands, quite nasal.
