Does anybody know anything about the Leak Sandwich speakers, in particular the bass drivers? I have the opportunity to buy a pair for £20 and wondered if they are worth keeping as they are, or possibly if the 15" sandwiched woofers could be re-housed. They seem to be in good working condition.
Thanks

Alnico or ceramic ones?
£20 seems about right for a good working pair of ceramics, a bargin for the alnicos (the little mid-tweeters will fetch at least the £20 asking on eBay)
I haven't seen many vintage boxes worth keeping around, the Leaks thou are pretty good....
Mind you i've only seen 12" ones (and seemingly always 1 alnico & 1 ceramic in a pair). The mid-tweeter deserves a better box if you are going to go ahead and use them.

Thanks Dave. Did Leak do alnico and ceramic versions of the Sandwich then? If you have any idea of the driver parameters it might give me an idea of what to do with them (a search on the net hasn't revealed much detailed info). From what you say though it seems like they might be worth getting anyway.

With the mid-tweeter attached to the grill, you can tell right away... do check both as it seems the alnico are from the mono days and often a 2nd speaker (from the ecramic days) was added to make a stereo "pair"
good luck

Alnicos have soup can shaped magnets, ceramic ones are pancake -- the woofers have square magnets, i can't remember whether the mid-tweeters are round. Since the mid-tweeter comes out with the grills that is easiest to check

I have just been repairing a pair.
The bass speakers are definity worth getting, regardless of magnet. Just be aware that the cone "break up" is fairly low so a good crossover is required.
Unlike Dave, I am not so shook on the mid/tweeter. Leak made a number of diferent types for use with the bass driver, initially paper, then stressed foam/al sandwich, then a unit common with Wharfedale that had holes punched in the cone.
The sandwich version I know, and it is quite good, but rolls off quite badly at the top end, so Leak in their later models added a dome tweeter to make a three way.
The construction of the mid/tweeter is particularly nice, with the front assembly including cone and suspension bayoneting onto the magnet.
Leak also made an oval roughly 6x8 sandwich bass unit for their bookshelf speakers. I have one and would like another if anyone has one lying about.
