Scounged up a new pair of speakers

For some reason dad forgot to sort out one of the office filing cabinets when moving, and I found a trio of old speakers that were supposedly busted. One of them was a cruddy old one I couldn't be arsed to even test, but the other two were pairs of old altec lancing speakers that felt *heavy*. Geek's first law of salvage - if its heavy, test it. I only have one power supply, and input cable (which seems to be shot to hell. Wavering between testing and re-jacking it, or making a nice little cable for it - I should have the parts to make one, or I can go grab one). They're Altec Lancing ACS91s and for 'busted' speakers, the ones that work sound pretty darned good. 

I need to get the dog out of the way to test it, musicwise (Ash hates anything but classical), but initial impressions seem pretty good.
