Question: Are other owners detecting a hum from one of the speakers or the sub when there is no input, but the bass vol is turned up more than 1/4?
Document: I turned this down to about 50% and turned the Cyber Acoustics volume up instead and with this setup the base boomed and the the speakers are now crisp and clear. Must admit I have the bass adjusted to almost to max. But Wow the sound is nice!BTW I have no hint of hum that is mentioned so often in these reviews. Don't know if this is an infrequent issue or if I am just lucky. But it is not in the ones I have. Enjoy!
I have never owned any Cyber Accoustics products, always seeing them as a low-end brand. I was pleasantly surprised with them. My Klipsch 4.1 system went out and I could not afford to buy another high end system. The CA was a good alternative. They produce a good sound and a good amount of bass. I am very happy with the bass and the highs and mids.
Right out of the box, I knew there was a problem. I hooked everything up and turned on the power without even connecting an audio source, and there I found a very annoying, noticeable, steady hum coming from the speakers. I thought to myself, "maybe it's because there is no source". So I hooked up my PC, got the same hum; played music, got the same hum.
I have the CA-3602a which has worked beautifully. I needed a new system for another computer, so I thought I'd step up to the CA-3810. The first one I received had the dreaded hum in the bass others have mentioned. Hum means poor shielding. Computer monitors often produce hum in poorly shielded audio equip. So, I plugged them in in another room with no other electronic equip, but they bass still had the hum Thinking it was just defective, I returned and re-ordered.
These speakers look to be quality made and the sound is quite acceptable. The remote that is wired and lit (very pretty blue circle on it) is acceptable. I wish that it wasn't wired though. I only have one problem with them that the base is way to strong for the smaller speakers and it can never be turned up much. You can never use them turned up close to the strongest because that base sound is to strong and over powers and destorts the overall balance and how the music should sound.
This is a case of you get what you pay for. Possible this product was defective as with zero volume the speakers had a loud hum. With volume the sound was as if coming through a tin can and the subwoofer had no thump at all. This product from my experience is absolute garbage. Good for simple beeps to let you know windows just booted up, nothing more. I quickly sent back and bought the Klipsch ProMedia 2.1. Amazing quality, high end sound and bone rattling base.
But if your like me, and enjoy a wide range of use out of speakers, these suck. Audio at low volumes is overtaken by an unbearable hum. Very poor quality amp in the sub.
These speakers are fantastic for the price. My only gripe, and its a very minor one, is the low hum you hear when they're on. But, you don't hear it at all once you start playing something through them.
This system sounds good, however the sub/amp emits a constant, incredibly annoying humming noise whenever it is on. This noise is quite perceptible in a quiet room or even with music playing at lower volumes. Also, the volume control wheel feels cheap and flimsy. The hum is problematic enough that I am returning the speakers despite their adequate sound quality.
This speaker system was small enough to tuck in the corner behind our kitchen TV so that the sub is hidden and the main/side speakers are not obnoxious. Very happy with the sound for the price, though the sub is picking up a hum - not sure if it's coming from the close proximity of my TV-speakers-power outlet arrangement or is inherent to the speakers. I am at least an amateur audiophile, so I'm also picky about these things.
Answer: No, Question for you. Did you use all 20ish feet of wire that shipped with the speakers, If so, that is most likely your problem, use as short of wire are possible to reduce the chances of electrical signals feeding into the speaker wire. I took that wiring and threw it in the garbage, grabbed some slightly thicker wire cut it to about 5 inches for signal and ground then soldered the crap out of everything and covered it with shrink wrap. I also reused the OEM connectors.
