C10 Posted May 27, 2021 Share Posted May 27, 2021 Title pretty much says it. Have searched for it but could not find it anywhere. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
Shakeydeal Posted May 27, 2021 Share Posted May 27, 2021 I can’t help you with the info, but if you need this to assist with pairing an amp I can tell you I achieve extremely loud levels in a 15x26 room with only 14 watts. Nice tight bass and extended highs, no apparent dips. So my informal assessment is that the impedance curve is pretty flat. Quote Link to comment Share on other sites More sharing options...

Nice tight bass and extended highs, no apparent dips. So my informal assessment is that the impedance curve is pretty flat. Reason for asking is mostly to see if there are any dips that would make the 4 OHM tap on my amp preferable to the 8 OHM tap (tube amp), even though they are nominally rated 8 OHM. My guess is that it dips some in the bass, since using the 4 OHM tap seems to tighten it up some. Just curious to what the measurements say and whether or not they confirm my ears.

Shakeydeal Posted May 27, 2021 Share Posted May 27, 2021 Understood. I have tried both taps but prefer the 8 ohm. Matter of taste I suppose. Quote Link to comment Share on other sites More sharing options...
mustang_flht Posted May 27, 2021 Share Posted May 27, 2021 Hi @C10 I have CWIIIs, but I imagine the curve is almost the same at K33E. My experience with my McIntosh MC2125: it works better and the sound is better on the 8ohms terminals, because on the 4ohms terminals the sound is softer in the bass, but beware this is only valid for CWIII + MC2125 and also for my ears. I think the wiser will be to listen to the wedding with your amp first in 4 ohms, then in 8 ohms and your ears will easily choose for you which you prefer. Technically no problem to connect in 4 ohms or 8 ohms it is just the quality of the restitution which will change. The curve of CWIII, for the moment impossible to find the curve of CWIV on the net https://www.audioreview.it/wp-content/uploads/prove/storiche/klipsch-cornwall-iii.html/misure-cornwell.jpg https://www.audioreview.it/prove/storiche/klipsch-cornwall-iii.html Quote Link to comment Share on other sites More sharing options...

Agree on the ears thing. 4 does sound better to me in the bass. Sounds clearer/more defined than 8. The difference it subtle though. Reason for the wanting the curve is mostly to see if it corroborates what I am hearing. 1 Quote Link to comment Share on other sites More sharing options...

C10 Posted May 27, 2021 Author Share Posted May 27, 2021 Yeah, love the amp! Bob take is to go with whatever sounds better, which is what I did. It is mostly just curiosity that makes want to see the curve. Quote Link to comment Share on other sites More sharing options...
Deang Posted May 27, 2021 Share Posted May 27, 2021 I always ended up back on the 8 ohm taps regardless of the amp I was using. Quote Link to comment Share on other sites More sharing options...

Only a little different in the frequency range from 700Hz to 5kHz but nothing real important IMO. The frequency response it much more different between the two models. 1 Quote Link to comment Share on other sites More sharing options...

Slowestrider Posted June 7, 2021 Share Posted June 7, 2021 I tried the 4 ohm on the Willsenton R8 this morning. Bass got tighter, sound stage deeper but narrower and it is too studio/artificial sounding. The 8 ohm connection is more real, natural sounding. I switched back to 8 ohm.

Deang Posted June 8, 2021 Share Posted June 8, 2021 First it goes waaay up, like 20 ohms, then it goes waaay down and bottoms out around four ohms - and then up again, down again, and up again and then off the edge of the graph paper. 1 Quote Link to comment Share on other sites More sharing options...
