KG2 13"wide x 11"deep x 19"tall, Ohm rating?

[Stubbs]

These speakers are NOT the bookshelf speakers at 4 Ohms.

 

I purchased them new, manufactured 08-31-1990, with the Oak Oiled finish, Green grill cloth.

 

What is the Ohm rating for these speakers?   I'm thinking 8 Ohms.  Is that correct?

 

Thank you,

Steve Stubbs

If you measure them you will find the DCR is less than 4Ω.

 

Yes the impedance is higher at some frequencies, but for all intents and purposes I would call it a 4Ω loudspeaker.

 

Unless the amplifier is rated for at least a 6Ω load, I wouldn't even consider running a 4Ω loudspeaker.

 

you've gotta ask yourself one question: "Do I feel lucky?" Well, do ya, punk? (Dirty Harry)

Thanks Klipsch Fanatic, for the prompt post.  Unfortunately, I am not audio tech savy and do not understand DCR, nor the relationship between amplifier ohms and speaker ohms.

 

I've have the documentation that all of my other Klipsch speakers in my 5.1 channel setup are 8 ohms.  Is there a way to check my serial numbers against a Klipsch data base and find out the ohm rating for these KG2 speakers?  These speakers are probably 6 inches taller than the bookshelf KG2 speakers shown at the Klipsch website, which did say the bookshelf speakers were 4 ohms.

 

My situation is that I am thinking of replacing my Onkyo TX-NR708 AV receiver with the Onkyo TX-NR636 AV receiver.

 

The TX-NR708 amplifier lists: 

 

110 watts minimum continuous power per channel, 8 ohm loads, 2 channels driven from 20 Hz to 20kHz, with a maximum total harmonic distortion of 0.08% (FTC).

 

120 watts minimum continuous power per channel, 8 ohm loads, 2 channels driven at 1kHz, with a maximum total harmonic distortion of 0.7% (FTC).

 

130 watts minimum continuous power per channel, 6 ohm loads, 2 channels driven at 1kHz, with a maxium total harmonic distortion of 0.1% (FTC).

 

(Others)

7 ch x 170 W at 6 ohms, 1 kHz, 1 ch driven (IEC).

 

Then under the Dynamic power section it lists:

 

250 W (3 ohm Front)

220 W (4 ohm Front)

130 W (8 ohm Front)

 

 

I have no idea what this means, other than my 8 ohm speakers and 8 ohm sub-woofer are working, and the KG2 speakers are working.

 

I've yet to find the Amplifier power stats for the Onkyo TX-NR636.   I am trying to determine if my current speaker configuration will work with the TX-NR636.

 

Any suggestions or advice is greatly appreciated.

Steve Stubbs.

Your amp is rated to drive 4Ω, so you shouldn't have a problem.

SOLVED. 

 

Thanks for all the advice.

 

After reviewing the specs on the new Onkyo AV receiver I was considering, I've decided to stay with my current THX certified Onkyo receiver.  The first Onkyo THX certified receiver in current production was more than double the price that my unit purchased in 2010 cost.  So I would have been coming down in capability, and my engineering side would not allow me to do that.

 

After recalibrating all my Klipsch speakers to my Onkyo receiver in THX mode, alll is well and exciting.  My only question is, "Why did it take me so long to recalibrate?"

 

Best,

Steve Stubbs
