There should be a volume control and contour control on the sub woofer box, If this isn't the case then there might be something else wrong with it.

Have you adjusted the subwoofer level? there should be buttons on the remote to adjust this level. Also, make sure you are not in a 'night' surround mode - this drops subwoofer levels a lot

Why am i getting sound out of my subwoofers but no bass


Check your strings on your amp they have low pass and high pass filters do some research online on those i cant remember which one it is i think its the low pass that only let low frequency sounds come out of the subwoofer i think mine is set at 110 to 120. Or you could try head unit settings

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..

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.

Subwoofer output no sound...


Check to see if it is properly hooked up to the player, and if it is, then either the amplifier's LFE(Low Frequency Emitter/Subwoofer) channel has failed, or the CPU is not beginning to forward frequencies 200Hz and below to the subwoofer. At 200Hz, the subwoofer adds to the satellite speakers, an then at 110Hz and below, only the subwoofer is playing.

I am trying to hookup my AL subwoofer to my existing comp system.Inserting a wire jack into one of the comp spkrs and subwoofer shuts the sound off.?? It is a FMC0034326 Altec Lansings Subwoofer.Thanks.


You can't just do that. Your sound card needs to have a specific jack just for subwoofers. If you plug it into the speakers, the computer recognizes the subwoofer as a pair of headphones and routes all sound through it. Remember, a subwoofer is not a normal speaker. It only allows a frequency of extremely low sounds (a.k.a. BASS) and won't play anything that you would need a tweeter for.

Powered Subwoofer hits hard even on dialogue.


This sub doesn't have a gate (keep the sub from engaging when the source level is low) so it'll "hit" for any input signal. What it does have is an adjustable frequency low-pass filter. If it's kicking in for sounds that don't need big bass reinforcement, try turning the filter to a lower number. The sub will then only kick in for really deep sounds.
