[putting a 4 ohm Tweeter into KLH 6]

Roy,

Your answer is as expected.

Gratifying to have you chime in. Same to you JK on both accounts

I am especially proud to own several pairs of the sixes. Learning what HK said after I bought some of these speakers was pretty cool, loved them instantly when I first heard them.

I know I'm pretty foolish to try and improve on his design.

My high frequency hearing is poor, very.

I guess I'm trying to compensate.

Sir... you are on it.

I continue to view your historical writings and see that you continue to be very active and as knowledgeable as anyone probably, at my level anyway you are and have been for quite some time my reference and I thank you.

[AR 1 questions]

Hi, guys a little bit off topic but I am considering the small, round Heil tweeters into an unmodified KLH 6.

It happens to be a direct drop-in fit.

Any comments would be appreciated, thanks!

What is the risk for any damage to any of my components and what do I need to avoid doing that will damage the loud speakers with this mod?

I am simply wanting to try it and see what it sounds like.

Many thanks to all of those that replied!

2 hours ago, RTally said:

The back of my KLH Six is labeled 8 ohms. I assume that means the tweeter has nominal rating of 8 ohms.

If you replace an 8 ohm tweeter with a 4 ohm tweeter the crossover frequency will double for a first order filter such as used in the Six. If you do not change the cap values, you will end up with a hole in the frequency response between the woofer crossover frequency and the new tweeter crossover frequency. That is, the woofer will roll off at its original 1500 Hz crossover frequency and the tweeter will pick up at 3000 Hz, twice the woofer's crossover frequency. 

When replacing drivers, if an original, OEM driver is not used, the replacement driver should match the original TS parameters as closely as possible. If you do not want to rework the crossover, you need to at least match the driver impedance at the crossover frequency. 

My main concern is the potential for damaging hardware.

Incidentally I am told that these particular tweeters go quite low.

I don't know what anything else you said means.

Ohm, I don't even know Um's Law.

Seriously, bro I don't know how to solder.

Thanks, apparently you understand but I do not see the beginning of my question which says I'm going to use a substitute tweeter.

(Seems to have disappeared during my edit process which I did not realize, sorry.)

So what about driving these lovely speakers with something like what shows 75 watts on the meters of an 80 watt receiver please also, guys?

 

[putting a 4 ohm Tweeter into KLH 6]

From tempest series PS-8, measures 4 ohms.

Intend to do no modifications but will use one amp fuse inline and a Sansui 8080.

What do you guys think?

It is a direct fit; will drop right in.

Also, what about the same thing with an AR 2ax?

I have done this before with a Polk RT 16 with excellent results.

Can't seem to reach you.

[Need AR 2ax 3/4 inch tweeter]

Need 3/4" dome  for AR 2ax...

Thanks!

Seeking tweeters for ADS L780, first iteration.

Unsure of part number.

Is it to 206 - 0117?
