It was shortly after a storm when my sub quit working...i install home theaters at my job so i know its hooked up right and all the settings are right on my reciever but the power light still comes on when its plugged in but it doesnt make any noise. Ive taken the amp out and looked it over...nothing seems out of the ordinary and the fuse is still good. Any suggestions?
Try hooking up a different signal input to your powered sub, another
stereo or even a dvd players audio output to the sub will work for a
test. Just make sure the subs gain is down before starting. If it
still not producing sound, the subwoofers amplifier is bad. I hope this

In general higher speaker impedance is safer than lower impedance for the amp. Don't expect anything impressive re: audio output from a passive (unpowered) sub if your HTS says it pushes only 25 watts. Without frequency bandwidth and distortion noted the spec is virtually useless as a comparison.
The BU-1 is a powered sub that accepts either RCA Line Level or HIGH LEVEL amplifier power. If you use the latter, impedance is a non-issue because the input feeds the BU-1's internal amp, not the speaker directly. You should be okay.
Perhaps if we knew some specifics about the HTS we could do more than guess.
Open it up and see what is in there! You might find a fuse blown. It might have just blown, without a fault, if you are lucky. If not check out the part numbers on the amp board. All semiconductors numbers, then put the numbers into google. You will soon find out if they are obtainable!
I HAVE 4 PS212 AND FROM WHAT YOU ARE DISCRIBING SOUNDS SIMILIAR TO WHAT HAPPENED TO ME. PLAYING THE SUB AT FULL VOLUME AND CLIPPING OCCURED NOT KNOWING THAT THE FAINT SMELL WAS THE VOICE COIL BURNING AND CONTINUING TO PLAY UNTIL KNOW SOUND LESSON LEARNED BUY A BIGGER SUB SYSTEM OR REPLACE YOUR SUB WOOFER.
IN MY OPPINION THIS IS A VERY GOOD PRODUCT WHICH I HAVE BEEN ABUSEING FOR MONTHS . SO QUIT WHINEING AND PAY YOUR DUES.
The hum can be from the power supply not properly filtering, and or the output stage also has a short.
There is the chance that the speaker driver coil is now burned, or the power supply is now dead. If ther output stage is shorted and was putting DC on to the speaker cone, this will burn it very easily.
You should sent the unit out and have it serviced, unless you are properly trained, have the service and engineering manuals, and the test equipment to follow up on a proper repair and calibration.
Hello, Unfortunately your subwoofers amplifier circuitry will need to be repaired ,the amplifier is bad and kicking in to protect mode. This mode is designed for safety of the unit and user and sub should not be operated until repaired as it may incur more damage to the components. I hope this
