A replacement can probably be found at Radio Shack. Aiwa was owned by Sony until 2004 but has been discontinued.

Aiwa isn´t a good subwoofer. The best are Rel, Sonus Faber, etc.
Here is the characteristics:

.1 20 watts, Min. RMS at 4 ohms, from 40 Hz to 160 Hz, with no more than 1% Total Harmonic Distortion

The subfrequencies are below 25 Hz, but TS-W60 work over 40 Hz!.

Bass frequencies (woof) are from 25 to 50 Hz.

Bad, very bad.

Sell it and buy a good subwoofer.

JMG

Since they're all passive speakers requiring amplification, you don't connect them directly to that TV.

It only has digital audio out and earphone analog audio. No amps or direct speaker connnections.

You might want to look at the manual for things like diagrams.

YOU SYSTEM HAS TO BE DESIGNED FOR A SUBWOFFER, SHOULD HAVE A CONNECTION IN THE BACK RCA JACK THAT STATES SUB WOFFER

I tried unplugging and plugging the power and it's working again for me.
