Hello Dave,

To test if there is connection in the woofer/bass-driver, connect a 1,5 Volt battery to the terminals of the speaker.

If it moves the problem is probably the cross-over: Look for over-heated resistors (turned from grey to brown/black colour), melted isolation on the wires touching each other (causing short-cut) or missing connections somewhere in the network.

If it doesn’t move (most likely after your description of the wire/network) the problem is the unit itself, and you should look for another bass driver since they’re practically unrepairable.

The Beovox S45-2 is a very nice speaker – and worth keeping alive (even improving)

Good luck!

Thanks Claus,

I knew I'd seen a post on this but didn't find it when I searched.  Thanks for the link.  I'm not electronically gifted so was fumbling in the dark a bit.  The resistors (thin long grey 'things') look as I'd expect new ones to look.  No wires cross or short circuit with no signs of fraying or cable breaks - looks very fresh.  Coils look perfect and well fixed to the board.  In fact, the crossover network and wiring looks like new!.

I'll try the battery test.  What about the midrange speaker though?

I checked with the seller who of course assures me that all 6 speakers were working prior to shipping.  I know they are good speakers as I already have a set.  I may use these failed units as a test/learning exercise as I know I have other speakers that need refoaming, cap replacements etc.

Thanks for your help.

Dave.
