I bought "2" pairs on ksl some years back. I didn't know how much good suffering I was in for. "I thought they worked." I found that each had a sub, or woofer blown. They use non standard impedances and sizes. woofer"bottom" 13.8ohms, sub"top" 8.3ohms. They have extra magnet glued on them. So a Goldwood won't fit without a wood doughnut or bracing. I made a schematic for the crossovers, noted all problems. I managed to get 2 working minus a sub that was blown. To clarify; Speaker 1 and 2 both sub and woofer are blown, speaker 3 is all working, speaker 4- only sub is blown. Originals are unobtainium. A person could try recoiling them if they know how. I can't find much of any info on these since they might be made for a budget stereo system. I would take $40 per each pair, or a good offer since the buyer might be inclined to modify with newer speaker components anyway. The Phone listed does not accept texts. I have the grills to, but they need some work.
