daniel7y Posted June 30, 2013 Posted June 30, 2013 Hey guys, Wondering if any of you might have some input for me. I got these out of a retail store that closed down for free, and the tweeter is shot on one of them. These are the speakers: http://www.avaustralia.com.au/products/Redback-45-%7B47%7D-85W-100V-8-Ohm-Speaker-%252d-Pair.html They sound pretty good and I wouldn't mind putting them to use if I could get the tweeter working again. Not really sure where to start though in diagnosing the problem and how much it might cost - maybe worth more than the speakers themselves? They've been in use everyday for well over ten years now so they are well worn. Any help would be much appreciated...
BATMAQN Posted June 30, 2013 Posted June 30, 2013 Not sure if this is the right part but the website says mylar dome tweeter which this is, not real expensive either. Good luck http://www.parts-express.com/pe/showdetl.cfm?partnumber=270-175
LogicprObe Posted June 30, 2013 Posted June 30, 2013 Here's one in Australia. http://www.altronics.com.au/index.asp?area=item&id=C3010 Given that they are distributors for Redback, they may well carry the exact spare parts! http://www.altronics.com.au/index.asp?area=item&id=C0913
daniel7y Posted June 30, 2013 Author Posted June 30, 2013 Thanks for those links guys. Logic: I think that might be the same tweeter it looks identical. I'll have to have a look tomorrow though. Is there any way to check other than cosmetics? There's no stamp or anything written on my tweeter. Is there an easy way to test if the tweeter itself is blown or if it's something to do with the crossover? I opened it up and it looks like the crossover is just a single capacitor... Does this sound right? The connections for the tweeter are just piggy backed onto the woofer wires, with a single capacitor on the positive wire. Also - can anyone give any insight on Redback? I was just curious to know the origin of these speakers but I'm thinking they may be a generic make. The same speakers can be found with an 'Opus One' badge on them. I can't find a website for either brand.
LogicprObe Posted June 30, 2013 Posted June 30, 2013 Their store is in Springvale...........dunno where you are as regards to that. http://www.altronics.com.au/index.asp?area=cont Anyway, just give them a ring and ask. I'm sure they are just as helpful as the Sydney branch. Pretty sure that Redback is an Altronics house brand that they bring in from asia. There are over a 100 Redback products on their site. That single capacitor should probably be replaced at the same time, just in case. Use one of the same type with a higher voltage rating. The guy at the store should set you straight.
daniel7y Posted July 1, 2013 Author Posted July 1, 2013 Hey logic, thanks very much for the link! Great help. Turns out it was just the capacitor. Got a new one from jaycar, problem solved. They sound pretty good I reckon, considering they have only cost me two dollars lol What makes a capacitor go bad? I wonder if the others will go bad soon...
LogicprObe Posted July 1, 2013 Posted July 1, 2013 Because they build them to a price, the cap will be exactly rated and if someone turns them up full blast..........it's probably the first to go......cheaper than a tweeter, I suppose. That's why I recommended getting a slightly higher voltage one. I think I'd replace others just in case..........they don't cost much.
