Imsjry Posted November 1, 2019 Share Posted November 1, 2019 Looks like the specs list the Chorus II as 8ohm speakers but I've read some posts that confused me about that. If my amp has taps for 4 or 8, what do you guys recommend in a smaller living room for moderate/quiet listening levels? I did try both and honestly couldn't tell any difference but wasn't sure what sound quality that really impacts. Thanks all! Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted November 2, 2019 Share Posted November 2, 2019 8 ohms is the nominal impedance but impedance will swing over the frequency range. Quote Link to comment Share on other sites More sharing options...
Imsjry Posted November 2, 2019 Author Share Posted November 2, 2019 Yeah i'm reading a bunch on this and can't find a definite answer. Best i've gathered is just to try it and see if i can tell any difference and that it is really amp dependent. I'm using a budget Yaqin MC84l tube amp. The back of the speakers themselves say 8ohm on the connectors. I've just swapped from the 4 to the 8 ohm taps on the amp and noticed it got louder immediately without adjusting the volume up. Of course louder isn't always better and its not like the 4ohm tap didn't give it more then enough volume control. My ultimate goal is to get the best overall sound at lower listening levels which is my primary listening mode. Quote Link to comment Share on other sites More sharing options...

Of course louder isn't always better... Well I'm no expert on output transformers but I do know enough to be at least somewhat dangerous with advice. Not really. It's been a while but I believe you'd find the 4 ohm tap is closer (in terms of windings) to the common, thus the 8 ohm tap is nearer the input voltage. Should be twice as much voltage. That would account for the volume levels you noted. The overall speaker impedance is all over the place and you don't have a tap to match the values in the midrange anyway. What's most important is the lower frequencies, and there the speaker is probably 6 ohms nominal, so pick your poison. Whichever one the bass sounds less flabby. If it's night and day different you'll be extremely lucky. Otherwise it could take months and you'll never arrive at a "clearly better" connection scheme after countless trials. My advice is that whichever one has better bass control at 4:00 PM on Sunday, November 3, 2019 is the one to stay with. 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted November 3, 2019 Share Posted November 3, 2019 Use the 8 ohm taps. 2 1 Quote Link to comment Share on other sites More sharing options...
moray james Posted November 3, 2019 Share Posted November 3, 2019 by using the highest available tap you insure the amplifier has lots of resistance to push against and that will make your amp happy and more stable than a lower impedance, it also means that the full secondary of the transformer is loaded again your amplifier will be much happier with this arrangement. Multi tap output transformers are a consumer driven convenience "I want it all but I don't want to pay for it all kind of thing, they are not available because they make good design sense. 1 Quote Link to comment Share on other sites More sharing options...
Imsjry Posted November 3, 2019 Author Share Posted November 3, 2019 Seems like the 8ohm taps are where mine are staying. The bass sounds a little fuller and the overall sound has a bit more life to it compared to the 4ohm. The only reason I asked was due to the plethora of posts mentioning using 4ohm taps with Tube amps and Klipsch. At least with this particular amp and Chorus II, 8ohm is where they will be. Thanks for the replies all! 1 Quote Link to comment Share on other sites More sharing options...
Deang Posted November 3, 2019 Share Posted November 3, 2019 People say that because most of the Klipsch stuff dips kind of low at times, but it's only through a handful of frequencies. Throughout most of their useful range, impedance can be quite high. Quote Link to comment Share on other sites More sharing options...
