SOURCE: Red light and thumping sound,

If your talking about the thump thump sound thru the sub when in standby mode, here's a fix if your good with a small soldering iron. Remove the amp from the sub. Locate U301 on the limit curcuit. (the small circuit card standing up right) Replace U301 with a TL074IN (www.alliedelec.com part #248-0012) .35cents +S/H also remove R263 from the preamp board,add a new 1N4148 diode(#935-0242) .05 cents to the pre amp board. Connect the Anode of the new diode to the Anode of D101 and the Cathode of the new diode to the Cathode of D108. Replace amp and test. Thump thump should be gone.

Have an existing ts-1100 home theatre infinity speakers


You cannot use this system with one that does not have a Subwoofer or LFE (Low Frequency Effect) output. Unfortunately, this sub doesn't have a line-level (speaker wire) input. Sorry.
