I own a pretty basic system Kenwood HTB-503 Home Theater Set  The problem I have is more of an annoyance than anything else. The Amplified Subwoofer seems to have some major delay in turning on. Example...Watching a movie and once the action begins the subwoofer delays for a couple seconds clicks on and then works along with the other speakers. Really annoying hearing the booom click...BOOOOOOOOM!!!.....5 minutes later vroom....CLICK VROOOOOOOM!!! I guess what I'm asking is: how can I set this up so it stays ON instead of going on standby? I have Adjustments on the SubBox if it helps... Crossover Filter ON/OFF Volume Dial MIN/MAX Crossover Dial 60Hrtz-200Hrtz Feel Free to ask any questions ill be up for awhile tonight

If this is a self powered sub, it sounds like something is hinky with the power supply. I am not familiar with a standby setting on self powered subs, most I have seen are either on or off. Make sure your input cables are clean and solidly connected. Check all of the settings you listed to make sure they are firmly engaged one way or the other. Check the volume knob and make sure it is not dirty (turnit up and down several times while listening for cracks, pops, drop-offs, etc.). This can give you intermittent performance. Good luck. |

Have you ever calibrated you system? If not, this might be part of your issue. Most people set their crossover frequency on the Receiver to 80. Make sure all your speakers are set to small. Turn up the crossover on your sub to full. It's essentially setting the crossover to off since the receiver is handling all the crossover. Go to Radio Shack and get a digital sound meter to measure your db. All speakers individually should output around 75db at reference (usually 0 on your receiver). They say your sub should be a couple db higher, but varies between users. I have mine set lower as I have a really good sub. Check your connections for loose wires. After doing all the above, use your internal test tones on the receiver to see if the receiver turns on now. It should. If not, there is something wrong with the sub. My guess is that your CROSSOVER is set incorrectly and that is why it never turns on or turns on too late. |
| My guess would be the crossover is set wrong. If you have it set low it will only reproduce very low Hz sounds. Try setting it at around 120-150 hertz and see if it picks up signal from your amp better, if not check the sub-out settings on your amp. If they are set to 60 hz it is not letting anything above 60 out. |

My sub has sleep functions as well. But it takes about 15 or 20 minutes before it goes to sleep. Therefore, we only get the click one time (the first time it receives a signal low enough to activate it) then it pretty much stays on. Sounds like your goes to sleep rather quickly. I'd adjust the crossover frequency so the subwoofer handles more of the frequency load and then it has less of an opportunity to enter sleep mode. |
