These subwoofer-sized high quality steel laminate inductors were made (NOS) for Madisound Speaker Components under their Sledgehammer label. Their 15 gauge, low DC resistance (0.54 DCR) windings, along with their large steel laminate cores and overall design result in high, 350 watt power handling and low hysteresis distortion for the cleanest sound at high sound levels at low frequencies. Madisound currently sells, off the shelf, 16 mH coils for mid $40 and18 mH coils for $53 each. I'm selling my NOS, in new condition, at a 45% to 62% off Madisound's current price and at 1% tolerances since I measured each coil myself with my LCR meter so that buyers could obtain pairs of identical coils, i.e. matched sets. 


The price is $20 per each coil but prefer to sell in matched sets of two or more where possible at $40/pair.

Do not "Buy it Now" until you've made sure I still have the exact coils you want. Again, make sure you message me before opting to Buy it Now otherwise there could be mixups. 

The buyer pays for shipping based on location. Each coil weighs 1.75 lbs. So the weight for two is 4 lbs including shipping box & packing material. The weight I entered is for two coils for the calculated shipping but that's likely to be different depending on how many coils you actually buy and where you live. Don't worry, I can modify the shipping details once you commit to a particular quantity. I'll work with you wherever possible. Please message me in order to select the exact number and value of coils you want. I'll be glad to field any questions you might have. I've never sold a multiple of anything like this so please be patient and help me simplify this transaction for us all. This will be a learning experience and an adventure. The one photo enclosed should be sufficient to read the individual coil values. Happy shopping.
