DIANN 2pcs 180W 3-Way Audio Crossover Filters Frequency Distributor

they arrived in a box with no packing. as a result the largest inductor (on both boards) was dismounted ie broken wire tie. i installed new wire ties and checked wire connections. the plastic bags they were in, were cut and abraded, but no evidence of this happening in the box they were shipped. this leads me to think that they were packed that way. I really fail to appreciate this. they say its 4 or 8 ohm. its one, or the other, not both.There are solid technical reasons for this. the price was very good they are well made.
