SubWoofer Recently had to replace my Sub cause of the subwoofer not working(amp works fine as it powers all the surround sound speakers. Bought exact same used Subwoofer from auction site and the SubWoofer turns off from too much bass.(average volume is at 30'ish)I still get a picture but no sound from any speakers and the power light from sub turns off. I have to turn whole system off then on again and it works til bass gets too loud then i have to repeat whole process again. If anybody has any suggestions feel free to let me know.

Sounds like your original and this sub have bad amps. The amp for the sub is not the same as the amp for the other speakers. The old unit has a dead amp and this new one is on the way out. (Pulling too much current on high bass)

When the volume is low the subwoofer sounds good, but when you go up a little volume, the sound is more acute. I have two subwoofer 1000rms each, when use 500rms power aprox, it sound great, but when


If the sub doesn't appear to have any damage like broken surround or a torn spider then I would suspect the amp may be having problems. What impedance are the speakers, what impedance can the amp handle, how do you have it wired to the amp?

Htddw7600, brand new, sub amp is not working, only way to get any bass sound is to unplug the sub cable from back of main amp and touch it on side of sub out port.


H?,
You have a very good system...one of the best of SONY..SUB does not get activated automatically especially on STEREO mode.DIRECT STEREO Notes • No sound will be output from the subwoofer.
.your system has Dedicated Power Amplifier for 2 Externally Driven Sub-Woofers (200W RMS x 2)..in order to activate the sub woofer amplifier you need to make a selection on the surround modes while you are switching the modes of the surround you will see the speaker position on the display of receiver as well..if you do not see the sub woofer it wont be activated..Sound Field Program (A.F.D) is a good example to test it..
Take care and please Remember to rate/vote and give me 4 Thumbs Up

Hope this helps!

--------------------
Additionally please follow the instruction on your user manual to activate the SUB ,as is follows..

-----------------
BASS-OUT
Low-frequency (bass) signals can be directed to the
subwoofer and/or the front left and right speakers
according to the characteristics of your system. This
setting also determines the routing of the LFE (low-
frequency effect) signals found in Dolby Digital or DTS
sources.
Choices: SWFR (subwoofer), FRONT, BOTH
• Select SWFR if you connect a subwoofer. LFE and
low-frequency signals from other channels are directed
to the subwoofer according to the speaker settings.
• Select FRONT if you do not use a subwoofer. LFE and
low-frequency signals from other channels are directed
to the front speakers according to the speaker settings
(even if you have previously set the front speakers to
SML).
• Select BOTH if you connect a subwoofer and you want
to output low-frequency signals from front channels to
both the front speakers and subwoofer. LFE and low-
frequency signals from other channels are also directed
to the subwoofer according to the speaker settings. Use
this function to reinforce low-frequency signals using
the subwoofer when playing back sources such as CDs.

Have an older (6 + Yrs) VX-10A model, that's worked fine up until now. I recently moved, hooked up the same stereo and surround sound speakers, which worked fine, but the subwoofer made a loud hum as...


Disconnect the input and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

How to switch on Sub?


surround and subwoofer may not work if there is an additional graphic equaliser operating.
1. check in your receiver speaker setting ensure your speaker setup doesn not have subwoofer set to NONE. this will block any signal to your subwoofer socket.
2 when you select your surround sound setting setup, ensure you select the speaker mode you want, if there is a multicontrol knob, cycle through the choices
select subwoofer mode and set it to yes.
if you have set-up small speakers S in your speaker settings then it could be that subwoofer is set to yes automatically if you have large speakers L, subwoofer has to be set additionally in the subwoofer setting.
3 test subwoofer on alternative device to test it is working ok
consult manual on enjoying surround sound and adjusting the speaker settings.

Ashton home theater sub not making any noise


It sounds as if the amplifier for the subwoofer is shot. If the subwoofer has a seperate power cord from the rest of the unit, your amp is toast. If the subwoofer is powered by the same unit that is powering the other speakers it could be a loose connection somewhere.

No Soound on Subwoofer from Yamaha RX-V363


I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!

SA-AX720 no subwoofer signal?


THIS UNIT HAS NO SUB WOOFER AMP IN IT. THE ONLY WAY TO OVER COME THIS IS TO HOOK THE LEFT AND RIGHT FRONT SPEAKERS STRAIGHT TO THE SUB WOOFER AND THEN GO FROM THE SUB WOOFER BACK TO THE INPUTS ON THE BACK OF THE UNIT FOR THE FRONT SPEAKERS. THE SUB WOOFER THIS WAY WILL EXTRACT THE BASS AND THE FRONT WILL RECEIVE THEIR PART. THIS SOUNDS CRAZY AS HELL I KNOW BUT THAT'S HOW I GOT MINE TO WORK. THE OUTPUT FOR THE SUBWOOFER IS USELESS AND PUT THERE FOR YOU TO HOOK UP AN AMP FOR A SUB WOOFER. EVERYTHING HAS SHORT COMINGS, AND THAT'S THE ONE FOR THE AX-720.

Subwoofer just stopped working. There's power but no sound.


I have the same problem. My guess is that the subwoofer coil is messed up. You MIGHT have to get it recoiled. But before you do any of that get someone with a sub to play their sub in your car, if it works.... then your sub is messed up, if not.....then your amp is messed up ( trial and error ). Today i noticed my subs rubber surrounding is crooked, that may be the problem for me. Also when I press down on the sub it makes a sticking sound, like something came loose. So once i get everything opened and out ill let you all know the solution. Good Luck!
