Klipschorn problem

The new K-33's in my Belle clones meter 3.5-ohm each so that other reading does sound a little low. Not crazy low...but low.

So where does one go from here? If you think you have a partially shorted voice coil and you don't want to jump and buy a new one until you are certain. What about the woofer in the other cabinet? Is it reading the same?

 

Thank you for 'crystalizing' my thoughts....

 

Is that my next move?  De-solder a lead and check and check the resistance on the other speaker?

Would my lower reading yield the 'duller', quieter sound I think I''m getting?

 

Again, thanks to all for the help!

And also do you have access to another meter? As @PrestonTom suggested perhaps yours is "out of cal" or just not accurate.

If the insulation of voice coil wire has heated up to the point melting and shorting out some turns of the coil I would say "who the heck knows what that's supposed to sound like".

Yes, I do.  One digital, one analog.

 

They both read 2.7 ohms for the left speaker (the one I just now opened up...)

And, on the right speaker (the one I opened up first), I'm reading 2.7 ohms (I was getting 2.7-2.8 with the  digital meter)

The fact that the readings are essentially the same for each woofer using each meter indicates to me the resistance is not the problem. 

 

Have you tried switching the networks to see if the “duller” sound follows the network.  If that is inconclusive, I’d consider swapping the woofers to see if the “duller” sound follows the woofer to the other cabinet.

 

If I were convinced the problem is the woofer, I’d recone or replace both woofers.

Have you hooked your amp directly to the woofer(s) now that everything is disconnected? Don't get too happy with the volume knob.

I've switched cables, and I've switched out the amp for a different one...

I thought I did that before (I've started to lose track of the 'permutations.')

 

I got a slightly 'brighter' sound, but still not very much louder than it was before...

And I thought you still had the parts on the woofer door connected:) So which were it?

I have ZERO knowledge about electrical engineering (like you couldn't tell!), so what are the fuses in this system there to protect/prevent?

 

And why wouldn't having the wrong ones installed (20 AMP on both sides on the 'main' circuit, instead of 2.5's...) be an issue?

 

Again, my engineering 'skills' fall into the "Fire - Bad !!!" kind of level....

You got me almost ready to tear my KHorns apart.

I haven't tried it on the left speaker (the one I just disconnected). 

 

I probably should have, but since the symptoms and resistances were all coming out the same, I didn't do that one...

 

I'll try now...

It sounds like the other one did when I did the same experiment...  A little 'fuller" (i.e. I can hear the upper registers a little better) but everything - including the bass - still sounds muffled and muddy)

 

Thanks again for everyone's efforts here - I have a 'thing' here tonight for which I have to leave, so I'll be offline for the rest of the day...

 

Thanks again - I really appreciate everyone's help!  I am learning a ton!

They are there to protect the drivers for sure. And yes having a 20 amp fuse where a 2 and 1/2 should be is not good practice. But the 2 and 1/2 amp fuse only lets 25 watts continuous to be dissipated by the woofer. With a KHorn that should Damn loud but perhaps the PO got tired of blowing a fuse occasionally. But 20 amps? Too much. Because now your not protecting it much at all, in fact really not at all. But maybe that's all he had handy.

If I need to, I can deal with that...  Doesn't Crites have them for $310/pair...?

 

I just don't want to replace them only to find out there's an 'electronic' problem (i.e. inducer, capacitor, etc.) that I missed...

 

Thanks again all!

If it was an electronic problem, then you would have diagnosed that when you bypassed the crossover (direct connection to the woofer). The sound would have a bit more energy in the highs, but it would not have changed the "muffled and muddy" problem. BTW, it is unlikely that the inductor would be the culprit since they are usually pretty robust. Capacitors, however, can degrade over time, although the change is sometimes subtle and gradual.
