My gigaware subwoofer wont work


Audio subwoofers are used to augment the sound quality that is released by stereos and other audio component systems. As a result of actively using subwoofers, the sounds projected from the sound systems (such as music and voice) not only become louder, but also have a fuller output. Subwoofers, however, are not immune to problems. These issues often result in distorted sound.
Issues Among the most common problems of audio subwoofers is the loss of their bass effect while playing music or other sound files. The majority of people that experience this problem do so because they have installed their subwoofer on a different sound system than the one where it was originally installed. Additionally, there are scenarios where the subwoofer does not produce any sound. b> Troubleshooting b> Subwoofer issues are typically caused by one of two things: improper settings or broken receivers. You can troubleshoot the lack of bass or other sound effects that decrease the quality of sound by checking and adjusting the settings of the subwoofer as well as your audio system. Although subwoofers work on almost all types of audio systems, some have to be adjusted to ensure quality sound while utilizing them. Broken receivers, on the other hand, have to be replaced with new ones. b> Significance b> Fixing subwoofer problems proves to be important, not only because it will increase your enjoyment while listening to music, but also because utilizing a subwoofer improves the audio system's overall performance. When subwoofer issues go ignored, there is a tendency for the audio system to become overworked, as the user likely works the controls on the audio system rather than using the subwoofer's settings. As a result, additional audio problems may arise due to playing at full-blast volume and making other unnecessary adjustments to compensate for the lack of a subwoofer. b> Recommendations b> One way of handling subwoofer issues is by reviewing the owner's manual, paying special attention to the speaker settings. Different audio systems have their own recommended settings to ensure quality sound and that all the effects can be felt and heard while the sound file is being played. If the manual does not provide any recommended settings and/or adjustments, tweaking can be done on the audio system's subwoofer menu to create your preferred sound. Through tweaking, you will be able to find the desired quality, as well as detect and correct any unnecessary noises and vibrations coming from the subwoofer. b> Maintenance b> Audio subwoofer problems can be prevented by regularly cleaning and maintaining both the subwoofer and the audio system where it is connected. The speakers should be dusted off periodically to ensure clean release of sound and the wiring should be checked for open exposures. These exposures should be immediately repaired to prevent further damage. Fix a Subwoofer b> A subwoofer, or a "sub," is an important part of your overall sound system, whether it's in your home or car. A sub's most important quality is bringing out sounds you can feel rather than just hear. However, they are also susceptible to wear and tear from overuse, and the sound quality will be greatly affected by this. Here are some steps to fix a subwoofer.

Check with your manufacturer's Tech Support Web site. Usually with a subwoofer, the problem lies with the voice coil, which might just be burned out. These are usually fixed by sending them into the manufacturer, so determine how much you want to spend to repair it versus how much it would cost just to buy a new one. Roam through the Tech Support forums. It's likely that someone had the same problem as you with your sub, and you can run the symptoms past a few other consumers to see what diagnosis they found. Identify the specific problem if you can. You can look for tips to fix this problem on the manufacturer's Web site, or if you're technically savvy, you can try opening the sub and looking at it yourself. Two major manufacturers of subs include MTX and MK Sound. Check the bronze-colored coil underneath the foam cover. Note whether it looks worn, burned, warped or distorted. This may be the cause of your sub sounding fuzzy or muffled, which means it needs replacement. Look at the fuse inside the speaker and test it if you know how. This is a likely problem that causes your sub to power up improperly, play sounds at about half the volume or intermittently fade in and out. If the fuse is discolored or shows a short, you'll need to replace it.

I Need To Know What Size Box to Build.. To Get The Best Sound Out OF The R 10's


Depending on the amount of speaker that you have, Alpine recommends that you use anywhere from .85 cubic feet to 1.25 cubic feet per subwoofer. This choice will be reflected by the sound of your subwoofers. If you choose to use .85 cubic feet per subwoofer, you will get a tight sound without excessive cone excursion.
However, if you decide to use 1.25 cubic feet per subwoofer, your subwoofers will hit lower notes and be able to handle more power.
These are factors that you, as a listener, will have to bear in mind when choosing a subwoofer enclosure. Regardless, enjoy your speakers!

How to set up a soundbar with a subwoofer. Where to place the subwoofer. Does it need to be behind us? Is it ok if its in a corner? Will it sound as good if it is in front of us next to the tv?


The subwoofer deals with low frequencies, which are not very directional (ie, it's harder to tell where the sound is coming from).  So where you put it isn't critical to the sound, provided that it's not behind curtains or something that will soak up sound.  The bigger speaker you have in your subwoofer; the less important the position is.
Putting it in a corner is something you're going to have to try, but you may even end up with better bass if you do, as a corner can act as a soundbox and emphasise bassy sounds.  Conversely, your subwoofer may not like being in a corner and interference effects from the sound reflections could degrade the sound.  Like I say, try it and see what it sounds like.  It depends upon your subwoofer, what else is in the corner, precise positioning, and how reflective to sound the corner is.  If it sounds terrible, move it a few inches and try again.

You can put it in front of you next to the TV, no problem.  The only downside it it's a big ugly box.  My wife always makes me hide my subwoofers behind something.

Subwoofer output no sound...


Check to see if it is properly hooked up to the player, and if it is, then either the amplifier's LFE(Low Frequency Emitter/Subwoofer) channel has failed, or the CPU is not beginning to forward frequencies 200Hz and below to the subwoofer. At 200Hz, the subwoofer adds to the satellite speakers, an then at 110Hz and below, only the subwoofer is playing.

I am trying to hookup my AL subwoofer to my existing comp system.Inserting a wire jack into one of the comp spkrs and subwoofer shuts the sound off.?? It is a FMC0034326 Altec Lansings Subwoofer.Thanks.


You can't just do that. Your sound card needs to have a specific jack just for subwoofers. If you plug it into the speakers, the computer recognizes the subwoofer as a pair of headphones and routes all sound through it. Remember, a subwoofer is not a normal speaker. It only allows a frequency of extremely low sounds (a.k.a. BASS) and won't play anything that you would need a tweeter for.
