Loose jack on subwoofer -- fixable?

see this instruction and fix it. God bless you

     Disconnect the coaxial cable at the back of the satellite receiver or cable box by unscrewing the coupler on the cable end.

     Attach the cable to the RF IN jack on a surge protector and tighten the coupler clockwise.

     Connect a second coaxial cable from the RF OUT jack on the surge protector to the input on the cable box or satellite receiver. If this stops the hum, congratulations: You're done.

     Unplug the subwoofer's electrical cord from the power strip or wall outlet if it is connected to the same circuit as the AV receiver. The amp in the AV receiver and the amp in the subwoofer are in conflict over the grounding of the electrical circuit.

     Plug the subwoofer into its own surge protector and connect the surge protector to a different wall outlet than the AV receiver uses.

     Disconnect the subwoofer cable from the back of the sub and the AV receiver if all other measures fail to stop the humming. Reverse the plug connections so the plug that had been connected to the receiver is now connected to the subwoofer. Turning the cable around may solve a problem known as ground-loop hum by reversing the shielding wire inside the cable.

The input jacks on the subwoofer panel are for connection of satellite speakers to it's crossover. The outputs are for the crossed over signal input to your receiver or amplifier, as there will be no amplification or channel processing from the subwoofer connection. It's only an optional crossover that may have a sonic advantage over the crossover in your receiver.

What you also can do is connect the speakers directly to the 703 and set the crossover frequency on it.

First go to this site and download and install this codec pack. Also, make sure you have your speakers set as you default sound device.

JBL Creature 2 are a computer speaker system designed and sold by JBL. The system is made up of two satellite speakers and an omni-directional subwoofer. The speaker system connects directly to a computer's available sound card output jack or a laptop's stereo output jack. Occasionally, problems can occur with the sound quality and connection with the speaker system. If there is no sound coming from the speakers, check the cable connections. Ensure the satellite speakers are firmly connected to the matching jacks on the back of the Creature's subwoofer. The connections are color coded and, in addition, each speaker connector is shaped differently to fit only into one jack. Ensure the output cable is firmly connected to the subwoofer audio in jack and the computer's audio-out jack. Ensure the power button on the back of the subwoofer is pushed inward. If everything is connected properly, the green lights on the underside of the satellite speakers will glow.If there is still no sound, tap the right-hand side audio-increase button on the right satellite speaker until sound is heard. Also ensure there is audio playing from the computer. Double check the lower right-hand side of the window's main screen and look for a speaker icon. If the icon has a red slash over it, click the icon and uncheck the "mute" option.

Hope this helps

the circuit board and amplifacation supply inside the sub are blow or shorted out.thus preventing any sound. the head phone jack works only because it is a bypass feature supported by the actual computer not the surround sound unit

Yeah man I have the same problem!
I guess I will just buy a new jack!

I realize you may have already doubled checked but make sure you follow this from the manual:
If the satellite tuner / cable box is equipped with an S video output
terminal, connect it to the S VIDEO 3 (or 4) IN terminal with an S
video cable. If it does not have an S video output terminal, connect
its video output terminal to the VIDEO 3 (or 4) IN terminal using an
RCA-type video connection cable. You do not need to connect to
both the S VIDEO 3 (or 4) IN and VIDEO 3 (or 4) IN terminals. If
the satellite tuner or television has component video outputs,
connect them to one of the COMPONENT VIDEO INPUT jacks.
With the initial settings of the TX-DS898, the VIDEO 3 and
VIDEO 4 input sources are set for the COMPONENT VIDEO
INPUT 2 jack.
If the video connection is made at COMPONENT VIDEO INPUT
1, this must be changed at the Setup menu: Input Setup → Video
Setup → Component Video (see page 35).
Using an RCA-type audio connection cable, connect the audio
output terminal on the satellite tuner or television to the same
VIDEO 3 (or 4) IN audio jacks on the TX-DS898. Make sure that
you properly connect the left channel to the L jack and the right
channel to the R jack.
If the device has a digital output jack as well, be sure to also connect
it to either a DIGITAL INPUT (COAXIAL) or DIGITAL INPUT
(OPTICAL) jack on the TX-DS898 depending on the device.
With the initial settings of the TX-DS898, the VIDEO 3 input source
is set for digital input at the OPTICAL 3 jack, and the VIDEO 4
input source is set for digital input at the OPTICAL 4 jack.
If the digital connection is made at a different jack, this must be changed
at the Setup menu: Input Setup → Digital Setup (see page 33).

Please check your model number, I can not find it on the JVC service website.

This is a powered sub-woofer I think. You need to have a thick black cord that connects the sub to the head unit. Then the satellite speakers get connected to the speaker jacks on the sub-woofer box. The sub-woofer should also be plugged into an A/C outlet on the wall.

The speaker outputs are labeled right there where you connect the speaker wires. You should see a red and black connector for each speaker and they are labeled "front right" "front left" "center" "rear right" "rear left".

If you do not have the thick black cord you need to connect the head unit with the sub-woofer, you can not use this system.

If you look at the head unit and give me the model number on it, I may be able to find the part you need. But I must have a good model number to work with, preferably from the head unit.

Shari,

It is my hope that I can help. This applies to the type of sound card on your PC.

- If you have a 2-channel sound card: Select 2 on the source selector switch on the subwoofer. Connect the green plug from the audio input cable to tyhe front jack on your PC sound card. With this input setting, your speakers will upmix the 4-channel signal and create a center signal for your speakers.

- If you have a 4-channel sound card: Select '4' on the source selector switch on the subwoofer. Connect the colored jacks on the audio input cable to the jacks on your PC sound card, making sure to match the colors.

- If you have a '6'-channel sound card: Select '5-1' on the source selector switch on the subwoofer. Connect the colored jacks on the audio input cable to the jacks on your PC sound card, making sure to match the colors.

Your sound card is located on the back of your PC Tower.

Good luck

I've got the same speaker system and have had trouble with the satellite speaker jacks causing them to cut in and out.

I disassembled the subwoofer to get at the jacks and repair them by resoldering some loose connections.

What exactly do you need as far as wiring descriptions?
