I did flip the cable to correctly match and it fixed the problem. I understand that you get the same dc voltage and it is safe. However it did sound different. Although the phase setting was correct on the subs, when standing a few feet away the bass seemed out of phase. When I flipped the power cord the sound was more in phase when listening from several positions. The ac cable itself was fine (it indicated the positive and negative wire). I am only suggesting that there be a marking on the sub's panel because the connection to wall is fixed due to the use of a detachable polarized cord. I would think that for the same reason it is not recommended to wire speakers out of phase you wouldn't do so to the sub's power. It has a negative effect on the sound (my personal opinion, but you can test yourself if you don't believe me).

Is there any particular reason Klipsch designed the new subs 350 snd 450 with detachable power cords? Doesn't this increase the chances of user error as far as AC polarity is concerned? After a recent visit to my local best buy to check out the new subs, this happened to be the case. The floor models were connected incorrectly on the subwoofer end (unfortunately there was no marking to indicate the positive and negative connection for the power cord on the sub) which resulted in an odd bass signal (it was there but it sounded like it wasn't). I think it would help if Klipsch would indicate in the sub manual why it is important to match the polarity correctly on the sub end of the ac cord. Also mark for ac polarity on the sub itself. If that is too much trouble, I think it would be best to stick to a non-detachale power cord or use a three prong for the next design.

I just purchsed the Synergy Sub-10. Do I need to use a y cable to split the signal L and R for optimum sound?

Wire on of your speakers out of phase with the other. Listen to music (something you've listened to countless times). Listen again with the correct wiring. It's not difficult to notice the difference. When out of phase, you lose bass, midrange, and some high frequency. Bass and midrange are affected the most I think.

I didn't think it was out of phase, it was behaving like it was out with any signal that was played through it. Dude, I know what out of phase sounds like. It was acting that way for a week. It was annoying because there was nothing I could do about it.

It was affecting separate systems throughout the house. All the systems in the house are correctly wired. I wired them myself and I am very particular about wiring. The systems have been acting fine for a year straight. All of a sudden last week I started having this problem. Very Strange. I double-checked all the systems to make sure. To see if I was right, I isolated the sound from my left channel computer speaker, then the right and compared both. The left channel was not producing bass correctly. It was "pulling" and the right channel was "pushing". But the computer speakers were wired correctly. Anyway, when I woke up this morning I played music and it seems the problem was corrected. Everything sounded in phase. I still don't understand why I was affected by it. Why should someone else's error affect me when I'm not even in the same building?

I am having a problem with all the speakers in my house. Specifically, all of the front left channel speakers are behaving like they are wired out of phase. However, they are all connected properly (red to red, black to black). I believe I am receiving interference from a system (that is incorrectly wired) that is not in my house, but located close to where I live. Is this possible? Is there a way to fix something like this? Or am I out of luck? Anybody on this board live in the Ypsilanti/Ann Arbor, Michigan area? Maybe you're being affected too and you can help me out.

I own KSW-15 subwoofer and I am using a Sony STR-DA4ES receiver. Sony recommends an LFE high cut at 120 Hz. Suppose I choose to go with this, where would I set the low pass filter to on the subwoofer? All my speakers are set to large(4 RF-3, RC-3).

Try both and go with what sounds good to your ears.

Set your speakers to Large. You may need to connect to both left and right inputs on the subwoofer. Make sure the crossover settings on your receiver match your subwoofer setting (if they are not you will get bad bass). I recommend setting it to 100 Hz or 120 Hz (whichever sounds better to your ears). After these adjustments, you should not need to push the sub's level past 12:00 position. Let me know what happens.

Both of these upgrades made an immediate, obvious difference. I also bought a pair of silver interconnects. The improvement here is subtle, but I do hear it. I think. My question, though is about burn-in. The manufacturer says there's a 20-50 hour burn-in during which the sound improves. Is this so, or is it another audio myth? How can something which has no moving parts need a break-in period? Or (the skeptic in me says) is the burn-in period a chance for the listener to convince himself that this small upgrade really makes a difference? ---------------- I would not say it is a myth. Anytime I have made a change to a cable in my system (power, analog audio) it takes time for the sound to improve. I never thought power cables would need burn-in time either. But they do.

Unfortunately it introduced high levels of EMI into my system. This did not only affect my home theater, but it also affected every audio system in my entire house negatively. I originally thought the direction thing was bogus too. After I changed them to the correct direction the difference was noticeable.
