true story

@Anand Singh,   Welcome to the Klipsch Community forums.   The first thing to do, if you haven't done so already, is to review the Cinema 600 support articles.    Klipsch has been very good at providing warranty replacements - if you are within your warranty period. If your warranty has expired, I'm afraid you are on your own.   The Bar 48 No-Power Repair Thread has become the go to place for all Cinema & BAR series soundbar power issues.    Then there is this: Cinema Subwoofers - Woofer Removal and Replacement.   I'm sure you can appreciate that detailed troubleshooting is difficult without access to the actual device. Once you have isolated the problem there's a good change the forums can help you find a solution.    

try this odd ball issue. Got two tower speakers from friend ,have never hooked them up to anything. So I repeat no power source  involved ! since   they've been in my home.  But; they seem to have what sounds like back feed coming from them? How does sound come with NO POWER! Troubleshooting is an understatement  I've checked  and tried it all. Still sounds like back feed???? I'm stumped!

@AndyMan_ this is nearly a 6 year old thread with many members who either no longer visit or visit rarely.  My advise is to start a new threat in the technical section.  But  be aware that Klipsch does not approve of modifications, therefore, you may get best results over at Audiokarma.    Technical section.   https://community.klipsch.com/index.php?/forum/28-technicalrestorations/   Audiokarma   https://audiokarma.org/forums/index.php?threads/klipsch-modifications.1008584/    

So I can help try to help, I am trying to keep things straight in my head. What Sony equipment do you have? Do you have anything else? And to answer your question: No, the tape out will not be suitable for powering the sub. 

@wetowne posted some insight 4 years back, maybe he can provide some insight on his current experience. 

@babadono, please update on your findings.    

I have a pair of Heresy II with the rectangular input cup. I replace the capacitors on mine last March.   There are four (4) caps on each crossover. The caps are soldered to a small printed circuit boardthat is attached to the cup with three (3) screws. The board also has the tips of  the binding posts that stick through the boards and has a bare jumper wire soldered to them. I had some trouble getting those wires attached as the jumpers are short and heat transfer caused the othe end of the jumpers to com un-soldered.   I came up with a soluution which I can detail if you wish. Different capacitor types will change the sonic signature of the speakers.   I'll post some pictures later when I have time.

What are people’s thoughts on powering Heresy IV’s with a Topping MX5?   I’d like an all-in-one Amp and DAC for simplicity. Topping are very low distortion Class D amps paired with quality DAC‘S, however they are extremely neutral with minimal sound colouration so I’m worried will make the Heresy sound too clinical, compared to a warm vintage sound with a Class A or tube amp.   Heresy IV’s will be mainly used for home theatre, plus the occasional listening session. I listen to all genres from classical and jazz all the way through to electronic and hip hop.
