Subwoofers are primarily designed as sealed cabinets but it often is possible to gain access inside by removing the speaker. I once had to extract a baby bottle that some child (or adult) shoved into the port.

SOURCE: i cant seem to get the sub woofer to put out sound

Hello, are you using the subwoofer output on the receiver?
Did you turn the subwoofer on within the receivers onscreen setup?
this requires going into the menu selecting speaker setup and telling the receiver that you do have a subwoofer connected.

if you have done all this I would try to fist make sure the sub is working. easiest way is to plug a source directly into the rca inputs of the sub and see if it powers up. A CD player or even an ipod with the right connector will work.

if the sub powers on and produces sound then the issue is in the receiver and you will have to play with the setup. Its possible that the output jack is bad, I've had that happen when I pulled on an RCA cable and pulled out the socket but that's rare.

Is the subwoofer set to turn on automaticly when a signal is sensed?
does it have a switch to select high or low level inputs (speaker jacks or RCA connections on the back)

hope that helps
remember start by making sure the sub works then figure out why the receiver isn't sending a signal.

SOURCE: I have a new LG

Yes, there is no problem here. Just make sure the load ratings for the speakers are not below the ohmage allowed by the LG system (4-8 ohms is standard). Your LG system will control the upper limit of filtered input to the sub. The sub may further filter the input with it's crossover, but it doesn't care that the mid and high inputs are absent. (The reason the sub input is marked as unfiltered is to let you know that it can take the full frequency range--not because it needs it) You are getting mid and high or possibly full frequency range to the accoustamass speakers. You should be able to filter the low end out using the LG controls to avoid overdriving the Bose speakers on the low end. Please let me know if you have more questions.

My small son throwed so many small toys inside subwoofer. How can I open and get rid of them? Philips subwoofer.

he must have done it through the port in the front of the subwoofer.
If you look in the back of the sub woofer you will notice a metal back plate with all the sockets and controls on it. You will notic a lot of screws on it, now remember only to remove all the screws close to the edge of the metal plate ( do not remove any of the screws in the middle portion ) about 8 to 12 screws. After removing the screws pull out the metal plate gently. There will be some cables attached to the plate , do not attempt to remove this !!. Shine a torch into the box and see if you can retrieve the toys from the gap you have created by parting the back plate.
After having removed the toys place the plate back carefully making suree no wire is trapped between the box and the plate. Put two screws on the opposite ends and then lift the subwoofer and shake it to confirm if any more toys are in before you put back all the other screws.

How to incrise the bass of sony MHC-RV777d

Is it possible that the speakers are out of phase, where one speaker is moving out, the other is moving in, resulting in zero bass?

Other than checking wires, making sure + on amp is linked to + on speaker, try changing the eq settings, or sit them next to a wall - walls help bass a lot.
