Re: klipsch sub 10 keeps blowing fuses
More than likely the power supply switching transistors have fried. Also check the large caps in the primary side of the power supply. If you don't know what your are doing do not attempt to fix the power supply.. very dangerous voltages involved !!! Send it to Klipsch for repair or purchase a Bash replacement panel http://www.parts-express.com/pe/showdetl.cfm?Partnumber=300-750

Where was it sitting before it was moved? Did it have it have more ventilation and keep cooler? This sub has a powerful amplifier in it. If it got moved to an area that restricts air circulation around the sub more it is possibly overheating and causing fuses to blow. Put a fan on it and make sure it is on a hard surface or up off the carpet at least to keep the bottom side cool as well. Also when one moves a speaker it's often to put it into a more convenient area to be able to turn it up louder with less disturbance to others. This will draw more power and create more heat within the amplifier than it's previous location. If this is so keep it as cool as you can and turn it down every so often to give the amp a rest. The key here is to keep it cool as you can. One thing you never want to do is put a higher rated fuse in than the unit is rated for. Always use factory recommend fuse rating.
The fuse blows when the current that passes through it are beyond its rating. This could be brought about by excessive consumption of the load, in this case the amplifier powering the sub-woofer.
Repairs would involve component level and require that you be familiar with electronic components and circuitry, use of a DVM and a soldering iron. Often it is just the finals that needs to be replaced. Of course we cannot discount the possibility of other components or section such as the power supply.
The smoke indicates something heating up such as a resistor or diode or a capacitor.
Should you be uncomfortable opening the unit and doing a DIY (do-it-yourself), then perhaps you need to seek the services of a qualified professional.
Should the downtime and cost of repair be no longer economically reasonable, purchase of a new unit might save you further trouble.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Others have had similar problems with the amp on this model. There is probably a circuit design error which causes some components to blow and as far as I've read, fixing it (or replacing the fuse) won't make the problem go away for long. Try contacting PSB or the retailer.
