I have KLH Model 32 speakers, from the early 1970's - my cat decided to sharpen her claws on one of the tweeters :-( and the paper covering is totally trashed. Do I need to replace the tweeter, or is some other fix indicated?

Cat'sneed to scratch. It's an essential part of their being! They scratch to sharpentheir claws and clean themselves. You can build your own if you like. Look atthis guide for a step by step guide http://www.wikihow.com/Make-a-Cat-Scratching-Post

the crossover inside the speaker box maybe burned out take out the woofer and try a diect connection from the woofer to the speaker wire.

Hi there.
Do you have the make and number on the back of the magnet?
Check if the tweeter is at all available on the net!
To have it repaired is also an option.
Iceman.

KLH 900B tweeter specifications: 6 ohm, 40 watts. By the way, KLH's QC for speakers could be improved. One of my 900B tweeters quit because the spacing for the voice coil was way off reasonable tolerance and the body of the speaker coil base pillar (ie: magnitized part) was off-center - and cauesd the coil to ware and short. I contacted KLH but they did not respond.

I am assuming you have the ACS 48's as your question was on this page. If not, these tips may work anyway. Firstly, the bottom plastic stands on the ACS 48 tend to rattle obnoxiously after awhile. Simply glue them on or somehow make it so they don't rattle. You can remove them easily to see if this is the problem. The face covers can also rattle, take these off as well, and see if that solves the problem.
The second problem I had was related to the tweeter in one speaker rattling also. I took a freshly sharpened pencil, and simply ran it around the far outside diameter of the tweeter between the case and the tweeter. Be carefull here, you could puncture the tweeter. If not deft of hand, have someone do it for you. Hope this helps
Thirdly, and most complicated, one or more of the drivers are blown. Find a used ACS 48 system on ebay, they are fairly cheap, or have the midranges resurounded at an audio speaker rebuilding shop. Not sure what to do if the tweets are blown, but if it were me, and it surely will be the longer I have these, I would take them apart, pull the tweeter, and try to buy new ones of better quailty. Thinking of doing this anyway. lol These are awsome speakers compared to what I hear in stores these days.

I know this sounds silly, but I had the same problem. Your speakers have a little plastic bulb that has been pushed in, right?

If so, simply put your mouth up to the tweeter, seal with your lips and **** gently (seriously). The tweeter dome should pop back out and in to shape.

It worked for me.

Good luck.

If you have a Ohm Meter, check the resistance to the speakers. If it is very high, the speakers are burned, (or the crossover is (just capacitors, and resisters...cheap)). If it is close to 4 ohms check the wiring and connectors..to and at the speakers, most likly the receiver/amp is not blown.

hi, have u first disconnected the tweeters and then checked, as if its on a cross over, the tweeter is in series with a capacitor,if u have a ohms meter or a continuety tester check the tweeter coil if its open,secondly you can have the coil replaced, check if u can get one before buying a new,let me know

This means that you have purchased a three piece home theatre system. Two tweeters and a sub-woofer. Assuming you are using a Stereo player (Tape/CD/DVC)you have to connect the Left Output of the Stereo placer to the Left Input at the back of the Sub-Woofer and the Right output to the Right input of the subwoofer by cables. Then take tweeters and connect them to Right speaker and Left speaker output at the back of the sub-woofer ( note if the speakers are marked L/R, then connect them to the subwoofer output accordingly. In case you are using a 5.1 player, then only connect the front right and front left to the Right and Left input at the back of the subwoofer. You are and you can now start playing your music or movies and and you will get theatre quality sound.
