Leak Sandwich

Yep, thats what I sketched with the box open. Nicely drawn, Dave.

The tweeter is right too.

I picked up a pair of Leak 2020 speakers last year for free on a freecycle scheme. I'm very impressed with them, coupled with a small T-amp. These have a ceramic sandwich bass and a ceramic tweeter. The cabinets are chip board but the internal sides have thick damping material applied .

The crossover appears to be 3 air cored inductors and a single plastic cap.

The bass is exceptional, but the top end sounds pretty rough. Each tweeter is covered by a piece of cloth , so hard to see them. Any advice on improving the top end ? Maybe I should remove the cloth to check the drivers are not damaged ?

Hi!

I've got a pair but the woofer cones are rubbing in both. Some six years back, I tried turning the woofers by 180 degrees, but it did not help. Both are Alnico, magnet woofers and the screws holding the magnet to the frame look like they belong in an aircraft wing (to hold the jet engines on...). Anyway, HAS SOMEONE ever successfully readjusted the voicecoil position on such a powerful magnet assembly, without cutting out the dust cap and shoving plastic strips in there, who could help me through it?

Thanks,

Long time ago but hey. Place woofer face down, undo four bolts till just free, taking care with vc wires. Move the magnet plate slightly, bounce the cone , when you hear no obvious rasping tighten nuts and refit. This way of centering normally proves adequate for all but the narrowest voice coil gaps.

The frame (basket) looks like Whafedale.
