Mine aren't the sealed version. I picked them up for about $45.00. After I bought them, I did some research and found out about the early sealed speakers. Thankfully, mine aren't that variety.
An audio buddy of mine has a pair of Fives that didn't tweet; he figured the tweeters were bad. I removed the tweeters and checked them out by running an audio signal through a 10 microfarad capacitor and they were both good. I recapped the crossovers and the Fives work great now.

I'm curious. I go back to the KLH 6 period and have followed audio since then and I've never heard of a ported KLH 6. Can you tell more about it, the difference from the sealed version and any history of it?
He means that the back has no access screws and the woofer
is mounted on the backside of the baffle...no access to inside
of the early version. I have those myself :(
Thanks, now I understand and your comment brings back memories of using the box as the frame for the woofer. I forgot about that.
Actually I wouldn't be too upset if they sound good. They most likely have the military grade oil filled caps which in theory at least don't go bad and don't need to be replaced. Now, if something goes wrong then you have a problem.
I think redoping provides a bigger improvement with these speakers than replacing the crossovers anyway, assuming all the drivers sound good.
Well they didn't seem to sound as good as the 17's I also have,
so I assumes it was the x-over. Could also be the porous surround.
But I'm determined to jigsaw the back off and make a new one.
Have no clue what the caps are.
No Sixes were ported. For the first few years(I think), the enclosures were completely sealed, and the drivers epoxied to the facing of the speaker. The grills were glued on so essentially there was no way the user could get into the speaker to replace a driver, or recap, etc. If something broke down(which didn't happen very often) you had to send it back to KLH for repair. Eventually in later versions KLH changed this and the drivers were screwed in and grills could be lifted off for easier access.
There was one pair of ported KLH speakers - the ones that came with the Model Fifteen compact. Of course the system came with all the wonderful copy they wrote about the "acoustic suspension" sealed enclosure design, but if you opened them up, you found this:
I must say they were the only small ported speaker I ever liked, though you did have to give them quite a bit of bass boost, which was built into the amplifier on the Fifteen. I wonder if Dr. Bose saw these before designing his version...
