This pair of speakers was originally to be attached to each size of a television. (I have no idea of the make and model!)
They are just over 65cms (29 5/8") long, 8cms (3 1/4") wide. there is a short (as in about 10cms / 4" long) connecting cable on each, which has a 2.5mms jack plug.
There are two brackets attached to each, and they can readily be removed with a Philips screwdriver.
I have not tested them but have no reason to believe that there is anything wrong with them. They have been stored indoors, in a plastic bag.
We are in GL4 postcode area.
