Low volume from subwoofer acs 295 - Altec Lansing ACS 295 Computer Speakers

From set up manual Setting up the system takes no time at all. Connect the subwoofer to the main unit with the provided cable. The NXT speakers connect directly to the subwoofer with color-coded cables for left and right. An FM antenna is included and can be connected easily to the rear of the unit (the AM antenna is built in.) Finally, the subwoofer gets plugged into the wall for AC power and the unit can be powered up. If this takes you more than 5 minutes, call your Dad and ask for help, you're probably over-thinking it. There is no setup in terms of volume or bass management configuration as the sub handles all crossover functions as well as volume balancing between itself and the NXT speakers. You can get a copy from manufacturer or online search

Why post the same question twice?

It's no clear what you mean by "I had to change the STK", but if that means you have somehow defeated the fusing or place a larger fuse than it requires then STOP and shut it off. You might be risking a fire or more serious damage to the amp.

I would recommend you find a hands-on tech to look at it.

If you have resolved the fuse problem and now just have low subwoofer volume, you might want to track it back to the source and ITS subwoofer volume setting. There IS a volume level control on the sub, too. Turn it up.

The manual is here:

if connector is broken, you need to buy a new connector, but it takes a little handwork and some tools a screw driver some electric iron and solder.

u need to open subwoofer case and check for the connector is soldered in a board is 2 jack 3,5mm female connector and one red mini-DIN connector. replace the connector take a attention on soldering the connector, dont damage the board wires and pins, if the iron above 300ºC.

take a special attention on electrostatic discharge, normaly burns sensitive boards.

The hum (50 or 60 Hz) is caused by the AC power getting into the entry point of the amplifier. Either the filtering capacitors from the powersource of the speakers have dried up - replace them - or there is a short in the cables.
There is another possibility: if you have kicked the subwoofer  box its transformer might have slipped from its fixings and now is touching the subwoofer speaker frame.
The only way to find which is to open the cases.

I have the same speaker set. maybe we can help each other. My plugs are all fine but my sub is not connected to anything at all and I need to know were they must go on the pc board. Maybe we can trade some photos on the wiring diagram?

Ok lets do like this
If you your mother board CD ,? get play that and you will find an option for sound and audio devices , please reinstall that.

I hope it will work .Please do reply..

Hello there
What kind of help on specific device from altec you need?
be more specific

You had the settings set incorrectly and overdrove it. The voice coil leads are burn't open. If you look at the little flexible braids by the terminals I'll bet they are black/brown and maybe even burn't in half. It's toast.

hi first buy a conductivity spray and spray on the dial and inside it if this wont help then just solder a knob which will fit good luck
