Hi all. Just moving into a new (smaller) place, I have a strange question, so bear with me. If the only place that my RSW-15 fits in the room is directly in front of a couch... and the most tempting thing in the world to do to it, is place ice cold beer bottles on it (which I could not stand) --- I wonder what would happen if I got a custom-cut piece of 1/2" tempered glass to sit on top of the thing, spaced with little rubber spacers? I have noticed that the unit is pretty stable even at pretty high volume, but I would probably discourage anyone putting anything on it when watching the Matrix... I guess I am wondering about how the glass alone would fare on top of the thing, if it were turned up (which it is going to be.) Would I be better off taking it off when I know I am going to be listening loud, and planning for an easy take off method, or do ya'll think it will be alright? Has anyone done this? I know that this is far from ideal, and I am going out on a limb here, but this is important for the WAF for the entire room, as I am sure that you understand. Thanks F

Hi all Just to keep you posted on this issue, the volume knob not working is quite possibly related to the loud hum I was getting, and it is the kind of thing you send your sub back to the factory to get a new one for. I am eagerly awaiting re-shipment. F

I had not even considered that proximity to radio stations might be a problem. I live right in Boston, and am surrounded by hundreds of those little college stations, I bet. I also have a few 40-50 foot cable runs to the rear speakers. Hmmm. I am interested in the things you mentioned that you could get for your cables? Could you briefly expound on them? Thanks F

Craig I just got the RSW-15 to match a pair of Horns, a Belle, and some Fortes, in a 25x50 sorta bright listening room, and really knocked my own socks off. I had a DVD-watching party last night and I thought the neighbors were going to come for me with pick-axes, it was so loud. (I lent the volume control to my friend for a sec in a fit of delirium...) I have not heard your Samson setup, but I think you would be hard-pressed to be disappointed with the RSW-15 (and the WAF is quite good -- at least here) Everyone is pleased but the neighbors! F

Hello all. So I got this sub, hooked it up, fought the hum problem for 12 hours, then finally got it going on, and popped in The Matrix and started to adjust the levels as appropriate. I scared the bejesus out of myself in the process. Even at low volumes, things were falling off the walls. I am definitely going to get evicted. No question. Also in retrospect, hanging the art glass thingies on suction cups on the windows was a decidedly BAD idea. There is a question in all this, I assure you. Does anyone know if the volume knob on the side of the sub is actually that? I have been able to find no discernable effect from turning this knob. Might I have a broken Volume control? I would have thought that I could hear the difference between all the way Clockwise and all the way CounterClockwise. Thanks in advance. F

Ok... round about 4 AM (after trying cheater plugs on everything I own, individually) I discovered that a cheater plug on the main power distribution (the Isobar) itself, was the trick. I am not sure how comfortable I am with everything cheated, but there you go, the noise is greatly lessened. Ear, to your question, with the interconnects disconnected, there is no noise. When I discovered this, I moved them Well away from the speaker and power cables. No effect. Anything that was attached to the sub via that cable (or any others) would hum. (Did I mention how loud the hum is?) I stands to reason that sub manufacturers would be able to detect a 60 cycle constant signal, and notch filter it out. Would it be so difficult to determine the difference between arrived-at 60 hz "music" and constant 60 Hz "noise". The more I think about that, it seems like this could only happen with some processing of the sound coming in, resulting in a delay.. hmm. maybe not so possible...

Just a little more, in terms of data points (I have been mucking about with it for a while now...) I remove the Line Ins, and power it up with no inputs, and there is still a hum (albeit not as loud.) This does not seem to be right to me At All. Further, I have been all over the websites of Klipsch and other manufacturers, but (strangely) the same text keeps popping up .... "Usually this hum is caused by a "ground loop". This is a problem that is sometimes created when connecting two or more electrical components together. Most times the problem does not lie in any one particular unit, but in how they're connected. If your subwoofer is connected to a different wall outlet than your system, move the subwoofer plug to the same outlet. This may require an extension cord just for the trial. If it works, you can permanently move the sub or use an extension cord. Please be sure to use a heavy duty UL approved extension cord." I thought that was strange.

Hi ya'll. I just bought a brand-new RSW-15. There is a Significant hum from the driver, 60 cycles. Really, it is loud as all hell, scary even. I have never had any problem with bad grounds, the rest of the system is as quiet as you can imagine... I have searched the boards for hum, etc, and I know the following things: 1) The unit ships with a 2-prong plug, so the cheater plug is no help. 2) No matter what outlet in the apartment I plug into, it is still humming. 3) The power cord is well away from the line-level cables 4) The Subwoofer line-level cable is a brand-new cable. 5) The pre-amp is the Aragon Soundstage, so I wouldn't expect a problem there. Menu settings on the pre-amp have no effect. 6) The hum persists when Everything in the apartment is turned off (lights, PC, Amps, you name it) 7) The only thing that affects it is to turn the crossover level below 60 Hz (as you can imagine) 8) The gain knob on the side of the unit has no effect on the hum I am so ready to answer questions on this.... I have run out of things to try. Thanks all, in advance. F
