Subwoofer problems

03-07-2007, 08:03 PM
I have an accurian (radioshack) subwoofer. worked great until all of the sudden at certain levels it produces a scratchy, crackling sound instead of thumps, bumps and the sounds you expect subs to make. Is this problem fixable? Is the sub blown? is the fuse blown? Has anyone else had this problem. thaks

Hard to say. Amp may be going out, even a poor internal connection could cause a 'scratchy' sound. So could a damaged speaker. hard to say without hearing it also. I would think if a fuse was blown it would not work at all. Most subs have a fuse you can replace on the rear panel. Have a manual with sub? might help....
If it is kaput, I think I would look for another. You can get a quality sub like Hsu and others for well under $300.

thanks for the reply, I think it might be kaputz. I just replaced the Accurian sub with a logitech Z-680 sub that I have had for a while. Althought connecting it up to my receiver was a little tricky because the logitech was a PC system with a 15 pin input for the controller. I think I might take the accurian speaker out of the case and replace with another woofer and see if that works.

is the sub's amp digital? sounds dead.

It could be a bubbled voice coil. If the cone tends to drag on something when moved by hand, that's what happened. The fix is to replace the driver.

The box you have could be upgraded with a better amp and driver. Check out www.partsexpress.com for some great ideas on that.
You could reinforce the box with some braces (often lacking in cheaper subs) add more 'fill' and put in upgrades components and end up with a much better sub for probably under $200.
If you are handy with tools, etc. could be a very rewarding project.
