Pair of Martin Logan SL3 electrostatic speakers in good condition. These are consecutive serial numbers from a non-smoking house. Note from the pictures - one of the terminals was broken during a move so I soldered a wire jumper. They work well and sound great - I reflected the defect in the asking price.
Available for pick up in the San Mateo, CA area or I can deliver within a reasonable distance. Shipping is pricey on these, they are large and heavy so local pickup is the best bet.
