I have a single cable to the left input now. I tried it in the right input and the noise persists. From what I've been reading I need to install a ground loop isolator. So, before I get into the amplifier I want to try this first.
I've been using a 3 to 2 prong adapter since the unit was new. The owner's manual stated to do this and there was a card that Klipsch had put in as well that said the same thing. So, I never assumed I was doing something wrong. What isolators (brand) do most people use?
Another question though, I was reading in the manual that if you use a 'Y' splitter to the inputs as I had been that there is a 6 db level increase. I'm assuming that works on a mono sub-out or as they referenced a 'single pre-amp output'. Just curious. Thanks.

Jason str - Thanks for the suggestions. I may have to look at the HSU line. I like the variability with port blocking, etc. The price point is definitely where I'm at. Have you listened to any of the Klipsch subs in the SW line? Just wondering how they would stack up.
Zeron - I appreciate the link. If I would have to add a capacitor and a resistor to eliminate the problem would you say that something is going wrong with the amp? I'm not against trying the suggested methods but am I band-aiding the problem? I understand that if it works than don't worry about it, but I'm not against a little upgrade either. I'm trying to give myself an excuse to do the later.
Thanks again.

Alright, let's set the world on fire. I mainly use this setup for music. I have my other Klipsch/SVS setup in the basement for movies and music. So, what do you guys like for subs? I'm not in the ultra premium, or premium, level range. I have two daughters. They eat money. I never thought I'd buy makeup, let alone at truck load levels. Anyway, I'm not a rap guy, old rock, new rock, R & B, etc. The SVS in the basement has always seemed lacking in upper frequency bass levels. The old SW-10 was/is, well, a little on the muddy side. I'm leaning towards a good sealed unit. Ported units drop lower but I like it on the tight side. Any good midrange price level suggestions to pair with the KG 5.5's?

I tried my other subs and no noise with cables connected to, or not, to the receiver. I'm starting to think it's time to go shopping......

I tried plugging my various cables into the receiver and sub with no audible difference. As far as shielding, I'm not totally sure. Had a 'Y' splitter to the original set of RCA's. Tried another set of dual RCA's and same issue. Went with a single Audioquest cable that I've had and same thing. The Audioquest cable was supposed to be mid level but I don't about it's shielding. I do have a couple of other subs that I could try. Like I said before, as soon as I plug an RCA into the sub jack the radio station comes in. Whether it's connected to source or not.

Yeah, I did that with a couple of different cables. As soon as I plug an RCA into the sub jack the station comes back. Thanks.

I've noticed in the last couple of days that my old SW-10 sub started picking up an FM radio station. It's in a master bedroom setup with some just as old KG 5.5's. It's the same station with each iteration of testing. I've changed nothing in the setup where it's been and have tested theories on cable coax, different sources causing it, cables, outlets, etc. Ultimately, it boils down to this; if the RCA cable is not plugged into the receiver, but is still plugged into the jack on the back of the sub I hear the radio station, slight humming. With the RCA cable still unplugged from the receiver and then I unplug it from the back of the sub the radio station goes away, still very slight hum. Having the cable plugged into the receiver did not worsen or make the problem better.
I'm just wondering if the old girl is starting to die. I'm curious as to what might cause this such as amp going bad, bad RCA jack, etc. So, I need to know if you're going to give me permission to start shopping for a new friend for the 5.5's. Any input is appreciated.

I just did the same thing and felt the same way. I have a pair of KG 5.5's and purchased the RB-81's because my wife wanted to downscale the size of the speakers. The RB-81's don't sound as 'full' to me as the KG 5.5's. Although, the RB-81's are impressive and after listening to them for a while I have come to enjoy the sound they put out.
You can push these speakers pretty hard and they keep sounding better as the volume goes up. I had to adjust the gains on my subs and volume levels of the other 3 home theater speakers to better match the sensitivity of the 81's. Once I got everything adjusted right I was pretty happy with the overall outcome.
I have a feeling though that if I biwired them and upgraded my amp, currently a Marantz SR880, they would perform a little better. The RB-81's are rated at 150W RMS and my receiver is running 110W per channel across the front.
Anyway, I still like the sound of 5.5's a little better. Considering I'm comparing a floor stand speaker with two active 10" woofers and a Tractrix horn vs. a bookshelf speaker with one active 8" woofer and tractrix horn, the RB-81's hold their own quite well.

Thanks for your help Prof. I received the tweeter on Thursday. Swapped it out and the problem was gone, except for the fact that I like the sound of my KG 5.5's better. Don't get me wrong, the RB-81's are a good sounding speaker. The upper range detail is a little lacking and the midrange is quite strong compared to my old 5.5's. I am comparing a floorstand to a bookshelf speaker though, further testing is inevitable.

Klipsch tech recommended swapping the grilles, the tweeter is attached, to see if the problem stayed with the cabinet, e.g. crossover, or followed the grill with the low output tweeter. When I switched them the problem followed to the other cabinet. So, I ordered a tweeter assembly. It'll be here on Friday. I'll post the outcome.
-
If I checked the right one, it measured around 5.6 ohms. I was checking the mid-sized yellow capacitor going to the tweeter positive output on the board. The tweeter plays but much quieter than the other. The solder joints appear to be fine.
A little more testing process detail, for a layman, would be much appreciated.

I just received a set of RB-81's and one of the speakers barely puts out any high end. I checked all of my connections and swapped the speakers left-to-right to make sure it wasn't a source issue. Next, I opened the speaker up to check all of the wiring and rebuilt the tweeter to make sure the diaphragm was set right.
Nothing I did changed the problem. Would this be a bad diaphragm or crossover problem? Any help is greatly appreciated.
SW-10 Starting to Die?

That's what I was thinking as well. The other two subs were two prong adapters. My SW-10 has hummed since day one when using the three prong adapter regardless of outlet, room, source connection, etc. That's why I used the two prong adapter. So, my thought here it to try an outlet side GLI vs a line level one for that reason. I may have had some noise at all times and didn't notice it before, or it started getting worse recently for some external reason.
I'm not doubting what you said about about the amp board. I'm not experienced in soldering to boards and therefore don't really want to try it and fry the board. I figured I've give the GLI a try and see if it helps.
