After additional listening, I'd like to add a few observations: - The noise is two-part, there's a high hiss (ssssss) accompanied by a low hum (mmmmmm) coming from both the tweeter and squawker. The squawker is by far the louder of the two. - These loudspeakers have the Crites titanium tweeter diaphragms (not sure if this might make a difference or not) - There looks to have been some soldering done to the leads to both tweeters. Each of the clamps has another wire soldered on to it, and the additional wires have been cut. I've never looked inside before, is this normal or a sign of something funny? I've attached a picture to show what I found. Thanks

Thanks for the reply. The amp was purchased brand new and I've had it for less than a month. The noise is more of a hiss from the tweeter (higher sssss noise), while the woofer makes more of a hum (low mmmm noise). For context, I have an old pair of Bose 301s that I've tried with the amp, and they produce a low volume hiss that is inaudible at more than a foot or so. Any help is greatly appeciated - thanks!

Thanks for the reply. Just to be clear, did sending the amp back have any appreciable effect on the hum? Would you advise me to have Rogue look it over, or is your opinion that the "budget" Rogue amps simply produce a hum through high efficiency speakers? Not something I thought of when buying the amp....

Thanks for the reply USNRET. The hum is there with no inputs connected, at zero volume as well. With or without power strip, using an isolated ground or common receptical. The amp is a Rogue Audio Cronus Magnum. So far they have been nothing but helpful in terms of support, I can't say enough nice things about Mark OBrien and his team there. I'm just holding out hope that there's a fix without sending the unit back in...or worse that its an issue with the speakers and amp pairing.

Hello All, I've recently paired a new (to me) pair of Chorus IIs to my brand new 90 wpc tube amp. I love the sound, but have been getting a relatively loud hum without any imput. It's audible at 8-10 feet, not super loud, but still there. It's especially bothersome during quiet passages in classical music. I've run through the usual drills, disconnected all inputs, plugged them back in separately, changed outlets, changed power strips, removed the ground with a cheater plug etc. All to no avail. I've contacted the manufacturer, who was kind enough to send a new (and they thought) much quieter preamp tube to fix the problem. No dice, it's still there. In communicating with the manufacturer, they seem to think it might simply be that the Chorus IIs are too sensitive (101 dB, I see). Is that reasonable? Has anyone else had a similar issue with high sensitivity Klipsch speakers? I'm contemplating sending it back for them to check out, but at 55# it's going to cost some money to get it there and back. Thanks for any insight - Matt

Thanks for the advice on placement. I took a minute to plot Colter's Rule against another commonly occuring function, with unfortunate results..... -

Thanks for the tips, I've been playing with the placement today and am glad to have a place to start. gpbusa: I'm glad to see you've also been baptized by Brother Bill Hicks....the man spoke the truth. -
Hello, I just returned from a sizable roadtrip to purchase my first set of Klipsch loudspeakers - a very nice pair of Chorus IIs. Does anyone have any pointers in properly placing these in a room? Any advice regarding whether they should be close to the wall, far from the wall, in the corners, toed in, etc. would be greatly appreciated. Thanks in advance, I love this forum. Matt
