Brendo09 Posted July 29, 2013 Posted July 29, 2013 Hi. I bought an Accusound Reference 8.5 series of speakers about 5 years ago. Two floor, two rear, one centre, one sub. I've got a stuffed centre speaker. Given that it can be replaced for $99 I thought it best to have a rip a seeing what the problem is and fixing it, given that I've got nothing to lose. When attaching a multimeter to the speaker connectors at the back of the speaker box, it reads infinite, so there's a break in the circuit there somewhere. I've pulled the two woofers out, and they read 0 when the probes are on the spades. I'm assuming they're okay. Problem is that the cabinet is glued together, making reaching both the tweeter and the hi pass filter difficult. Two questions. 1) Is it easy to open up the cabinet, or do I need to do everything through the woofer cutouts? 2) Is it as simple as tracing the wires and testing each length (a-b, b-c, c-d, d-e, e-f etc) until I find an infinite reading, then fixing that bit? Or am I off the path completely? I know it's probably not worth the time or effort when I can get another for $99, but to be honest, I want to fix it up so I can flog the whole setup off and start again from scratch. And $99 is a big chunk of the resale value (which, to be honest) is probably about $200 if I'm lucky. Please no comments on how rubbish they are. You don't know how disappointed I was when I reset this system up after listening to some fairly ordinary active monitors for the last 12 months. Just .... meh.
henry218 Posted July 29, 2013 Posted July 29, 2013 try to take out all the drivers and the terminal cups. from other member on this forum, accusound attached the xo on the side of the cabinets, i dont know if thats their standard practices, so you need more opening areas to reach to it.
henry218 Posted July 29, 2013 Posted July 29, 2013 whats the $99 for? drivers or passive xo replacements?
Gee Emm Posted July 29, 2013 Posted July 29, 2013 whats the $99 for? Beer & pizza whist doing the repair!
Brendo09 Posted July 29, 2013 Author Posted July 29, 2013 $99 is for a whole new unit. http://www.ebay.com.au/itm/ACCUSOUND-200W-REF-8-6XD-XTRA-DEFINITION-DOUBLE-6-HOME-THEATRE-CENTRE-SPEAKER-/271228986495?pt=AU_HomeTheatreSystems&hash=item3f2681e47f&_uhb=1 Like I said, it's not a top end unit. The XO (which I'm assuming is short for cross-over)appears to be glued on the back of the cabinet, beside the terminal cups (which again, I'm assuming is where you bang the banana plugs into the back of the speaker cabinet). Is finding the break in the circuit simply tracing through the circuit and testing the ends of each wire and the drivers / tweeter?
henry218 Posted July 29, 2013 Posted July 29, 2013 unless the parts failed, most probably the wires. trace from the binding post to the passive xo board first (or groups of components if its p2p wired) usually if certain parts failed, it only affects one of the drivers, if the whole speaker dead, prob the wiring. or shorted and fried all the drivers cheers henry
Brendo09 Posted August 2, 2013 Author Posted August 2, 2013 Turned out to be a cold solder that fell off the driver spade as I opened it up. Fixed up and ready to offload!
