Jantzen Wax Coil or Mundorf M-Coil CFC
Absolute low DC resistance in a coil is not always a good thing. A good crossover designer builds that into his design, and altering the DCR can alter the crossover. It's often a beneficial thing in that lit becomes part of the work to balances efficiency for bass output. Alter the DCR of the woofer coil and you alter the system balance. Alter the ESR of a capacitor going to ground and you can introduce some really odd impedance curve behavior. |
Hi @erik_squires, I like https://www.partsconnexion.com/ but they don’t sell inductors that I interest for Jantzen Wax Coils and Mundorf MCoil VLCU Paper Copper Film Inductors. I experienced one paradox. I have Altec 604E speakers. I used DIY German crossover built with autotransformer. The LPF iron core inductor DCR was 0.2 Ohm. Now I use n-1500 crossover with original old iron core inductor DCR = 0.32 Ohm and different modern PIO capacitors and Duelund resistors. Bass reproduction with German DIY crossover was bloated. Despite higher inductor DCR, bass reproduction with n-1500 is much more controlled, textured and detailed. I just want to add n-1500 has around +3dB output on 5K-10K vs German DIY crossover, that can be an important factor. Regards, Alex.

Hi @yuviarora , Currently I use vintage iron core 1.5mH inductors with 0.32 Ohms DCR. And I like how do my speakers sound with my current crossover configuration. I’m choosing between Jantzen Wax Coil 14AWG - 0.34R DCR and 12AWG - 0.25R DCR. Jantzen Wax Coil 14AWG has a very similar DCR to my current inductor. Any reason to go to Jantzen Wax Coil 12AWG? Regards, Alex. |
