KLH Model 23's

[crazy-in-az]

I just picked up some KLH 23's and I must say they are very nice. I had them hooked up to my Realistic STA-960 and was listening to the radio when "Another Day In Paradise" by Phil Collins came on. The bass and soundstage was incredible!

I took one apart to see if the crossover has been recapped and I was a little surprised. The crossovers I've seen online have 1 cap, 1 inductor and 3 resistors on the pot for tweeter level control. All that's in this one is an inductor on the woofer and a 4.7uf electrolytic cap and 8 ohm resistor inline with the tweeter; there isn't a potentiometer at all, just a bolt through the backplate and the words "Decrease-Normal-Increase" on it.

Anyway, they sound great, but I ordered some 4uf Solen caps to replace the old electrolytics. Here's a couple of pics, since I know my post is worthless without any...

Excellent speakers. Six's on steroids! They share the same woofer as the Fives so can take more power.
Your crossovers have been worked on. Clearly not the original cap there, and yes, the 3 position pot and resistors are missing.
Some pulled crossovers may show up on fleabay, so keep an eye out, and for now enjoy the sound.

The KLH Model Twenty Threes dos not have a potentiometer, or L-Pad. That's a 3-position rotary switch that switches between three different resistors.

I'm at work now, but I'll dig around tomorrow to see if I have a photo that shows the values of the resistors and how they are connected.

I suspect whoever worked on yours just removed the switch and hard wired the resistor for the Normal position.

Thanks for the information. I will take the other woofer out tomorrow and see if both crossovers were modified this way.

Here's an after photo of one of my recapped KLH Model Twenty Three crossovers:

It clearly shows the resistors are 8 ohm, 4 ohm and 6 ohm.

Okay I haven't had a chance to remove the other woofer yet, but I have spent some time listening to them last night and they are starting to grow on me. I've always liked speakers with extended treble, but these speakers with their trademark New England sound are really sweet to listen to. They aren't hard rockers obviously, but they still sound good with some Jefferson Starship. I'm just waiting for my caps...

They should sound MUCH better after you replace the caps. Those 50 year old Temple caps weren't very good when new. When I recapped mine a couple months ago, they were the easiest recap I've ever done and made the most noticeable improvement. As the saying goes, it's like the speakers had had a blanket draped over them. The new caps, any modern film cap, will dramatically improve the highs.

They can actually rock pretty hard. After the recap, and woofer reseal, they can seriously crank!

Truth. But I was never truly impressed with them until I hooked up my HK775s. These seem to be speakers that like lots of headroom on the amps.

Well, maybe after the recap and a little Thin Lizzy I'll change my mind.

Yes, they are great 2-way vintage speakers.
