Hi All. My friend asked me to take a look at his speakers as he didn't think they were working so i tested them on my amp and hey presto they appear to be okay, albeit with an issue on the binding posts. They have the bi-wire option and a couple of the binding posts have snapped off meaning it sounds like the connection between the low and highs isn't there so you can get either a very bassy sound or very trebly? sound depending which set you plug them into. In the process of messing around with them ive managed to snap another one off too.
I'd like to fix them for him (before he notices!) as it seems a fairly straight forward process but what i can't work out is how to connect them. They have little bolts on the back (once the main plastic box has been taken out from the speaker) so it would suggest they just unscrew but that is how i managed to snap the others. Is this likely to be just because the bolt has gone a bit stiff or do you need to get at them from behind with a tiny little spanner?
Finally, if i buy new ones will the cheapo ebay ones do? the speakers aren't particularly expensive and providing they work neither me nor my friend will expect anything more in the way of performance? and are they a standard size - 4mm seems to be the way?
