Klipsch KG4: 4 ohm or 6 ohm?

[travellersol]

I purchased a pair of 30 years old Klipsch KG4 just a couple of weeks ago. I looked at the back panel it says 4 ohm, but I do remember reading some owners having 6-ohm KG4s. Are there two versions made? Or is there anything I don't know, like, how many variations Klipsch made out of KG4?

i know they made 2 versions of the Fortes 1st was labeled 4 ohm and had a round terminal box second was labeled 8 ohm and a rectangle terminal box, ive also read that the impedence was the same and they just changed the labeling. i dont know about the KG4's but mine are dated 10/03/89 and are 6 ohm and have a round box,.

I had read the change was for marketing purposes. The same as saying "compatible with 4-16 ohm systems".

Mine Say 6 Ohms. I run them off the 8 ohm taps on my Tube amp

thanks. how can I be sure of the actual impedance? I need to know if it is safe for me to drive these together with another pair of speakers of 8 ohm.

Measure the posts with a DMM.

Hey, impedance varies with frequency (and power).
See post #4 of this thread.

The answer to your question as to whether you can drive two pair of speakers comes back to asking if your amp can deliver enough current as the impedance load drops. At low to reasonable listening volume you'll probably be fine with most any amp or receiver. If you crank it up, you may clip the output signal and blow your speakers and/or amp.

Mine say 4 Ohm. I drive them with 35 wpm Yamaha CR-620 receiver. I rarely have the volume knob past 6 o'clock and I get room (11'x14') filling sound. The receiver barely gets warm.

Question: why would you run two sets of stereo speakers at the same time? Comment; perhaps you need to purchase an amp that can run what ever it is you want to load it to and not piss around. Easiest way for you to tell if your amp is safe or not running what every you hook up to it is to monitor the temp of the heat sinks. If you can press the palm of you hand on your heat sinks and hold it there for a minimum of a full five second count before you have to remove your hand the amp is likely ok with the load at the level you are playing at. While this is non technical it is a good measure of the thermal level of your amp. If you cannot keep you hand on the amp for a full five second count just back off on the level til you can do so and you should be fine. This is assuming you have a decently built amp. If the amp thermally shuts down get a better or larger amp or just stop with the dual speaker load, it is not a good idea and it makes for all manner of inter speaker distortion. If you simply want more level get a more efficient or a larger pair of loudspeakers. Sounds to me like you need a pair of Cornwall or Chorus ll.

I've had both the 4ohm and 6ohm version at one time. I didn't notice any differences when playing both at the same time (A/B). I had these prior to the introduction of Dolby Pro-Logic. I later added a DRS-100 Pro-Logic processor and M-35 (2/4 ch) amplifier and a Klipsch Kg2 center speaker. Very nice system in its day.

For these KG4s', I have read many say that placing it 10" from the wall and raising the front about 2" will be good. What about if we just place them on stands of maybe 10" high, will this be good too?

Even better. They actually sound best on sturdy stands like you've mentioned. Mine are on floor with angles 2 inch stands and when I sit down and am at ear level they sound so much better. So having them up in the air at all times would be ideal
