The large dual line you are talking about sounds like the Coffin.
Yep thats the one. The driver is the B139 SP1044. I found the driver sheet on the page as well. Thanx a lot What is the going price for a pair of these drivers (B139 SP1044)? I know it is hard to get these speakers (especially here is South Africa) but I would really like to build a decent sub. Has anyone actually heard the Coffin? I am quite keen.
Does anyone know of a place that sells the B139 SP1044? I am trying to get someone that is comming from the United States through to here in South Africa to get me a pair of good drivers.
Thanx allNeopsp

That is my site. I have most of the KEF driver spec sheets up till about 1980... just need to find time to get them all scanned.

You have to stumble across some or buy them on eBay $200-300 USD a pr. If you aren't into the nostalgia factor, for sub use for the same dollars you can get a better suited driver new. The B139 is about equivalent to a 10". On my site there are some drivers listed that might be used as a substitute in the Classic enclosures, although you would be better off starting from scratch.

Quite a few back in the late 70s. In there day they were quite spectacular. A set of the medium price 12s (Shiva, Stryke, BluePrint, Titanic...) should be better.

Neopsp, I will try to scan it and mail you. Have some patience, I still have to install the scanner, and my ISP is having problems with the mail server (not only the mail server, but that ine is so bad the warned there might be lost mails). I hope the mail server is sorted out by the time I get it scanned.

Since this is a B200 thread, does anyone have any info on the SP1068 ("triangular" basket) unit used in the KEF 304?

I have a pair of these running 100Hz down and they work very well indeed.

A few years ago I was given a B300 12" Woofer. I wrote to the Danish importer about a datasheet for it, but they couldn't help me. Then I wrote to KEF directly and they mailed me a datasheet (took a few days IIRC). Give a try - the worst that can happen is that they say no

/U.

Eric,

I built a pair of those about 25 years ago. Great subwoofer, from an article in Wireless World.

Regards,
Jam

These were available here in AUS as a kit in the mid seventies.
I bought mine from a garage sale for AUS$30.00 a few years ago.
I have since disconnected the crossover, mid and tweeter, and am running them via a line-level crossover 100Hz down, with a pair of Canton 12" 3-way cabinets providing 100Hz up.
This present combination (expect it to change before too long......again.... ) works very nicely, and the TL subs will vibrate the kidneys, but no hint of boominess, just clean bottom end.
I like them too.

Eric.
