Luckiestmanalive Posted May 25, 2009 Share Posted May 25, 2009 Hi I've picked up a pair of damaged (and repaired) Audio Physic Sparks. See this page for details: http://www.audiophysic.com/download/spark/hifi_news_and_records_bright_spark.pdf One loudspeaker has had the mid/bass driver and the binding posts replaced. I have spent some time going through my music collection and love their energy and the soundstage they produce but have found that the damaged one (at least) is missing some details - eg a xylophone on one track is missing (but is there when I swap the channels over) and there is a lack of echo on another track. The replacement binding posts are loose and one (black) causes the music to cut in and out when wiggled. Anyone want to offer a diagnosis and cure? And who should I take them to? I would dearly love to make them both sing as one again... Link to comment Share on other sites More sharing options...
Owen Y Posted May 26, 2009 Share Posted May 26, 2009 Yes, sounds like poor or damaged connection at the post/s. I'd have them replaced. Or both ch's, with matching posts. If you are handy, try to get behind the rear plate to inspect & to tighten them. Soldering if necess. Link to comment Share on other sites More sharing options...
Luckiestmanalive Posted May 26, 2009 Author Share Posted May 26, 2009 Yay - thanks, Owen. That sounds like a small project even I might be able to manage! The binding posts on the undamaged loudspeaker are lovely. I wonder if I can get a matching pair... Link to comment Share on other sites More sharing options...
Omegaspeedy Posted May 26, 2009 Share Posted May 26, 2009 Also if one driver has been replaced it may not be run in yet making it sound a bit lifeless compared to the other. They didn't come from FB Audio by any chance? Link to comment Share on other sites More sharing options...

Omegaspeedy Posted May 26, 2009 Share Posted May 26, 2009 I just considered those myself a while back prior to building my own speakers. The asking price was good. They be fine I'm sure. Cheers. Link to comment Share on other sites More sharing options...
Luckiestmanalive Posted May 26, 2009 Author Share Posted May 26, 2009 Phew... I hummed and haahed for over a year before deciding to make them mine. Even in their current condition they sound pretty good but I can't wait to restore them to their former glory. Link to comment Share on other sites More sharing options...
Omegaspeedy Posted May 26, 2009 Share Posted May 26, 2009 Yes they will be awesome! unscrew the binding post housing and hopefully the crossover will be attached on or behind for you to make close inspection. check the wire crimps/solders and the inductor/caps/resistor solder joints too. Lastly you could unscrew the drivers themselves and check the crimps/solders. Best of luck, James. Link to comment Share on other sites More sharing options...
Luckiestmanalive Posted May 27, 2009 Author Share Posted May 27, 2009 Cheers. I'll have a look tomorrow and see what I can do. Turns out the original posts were both snapped in half so it looks like restoring them isn't an option... now, if only I knew some German...

Luckiestmanalive Posted May 28, 2009 Author Share Posted May 28, 2009 Wow! I'll get in touch with them this arvo. And thanks for the offer to translate but my fiancee is true blue so she can help me out if I get into difficulties with their evil version of our accent...

Luckiestmanalive Posted May 29, 2009 Author Share Posted May 29, 2009 Thanks, guys. I had to borrow a special screwdriver to free the circular wooden insert that contains the terminals. Once I removed it it was easy to locate the broken circuit, so I soldered it back to the terminal, tightened the screw so it wouldn't come loose again, and screwed the cover back into the cabinet. That has restored things to how they should be but I might take photos and start another thread in the DIY section to see what else I might do, once I get me a set of fancy screwdrivers.
