Here is a new version of the Altec N1201-8A crossover for Altec 802+416 drivers combo but with the blue 511 horn.
It replaces the GreatPlainsAudio version of the Model 19 crossover which is not up to what the drivers can deliver. I haven't heard the original M19 crossover but I thought that lowering the DCR of the main 2.5mH low freq coil would improve things in the low freq department, particularly driving the speakers with the ACA mini or the sony Vfet amps. I used Solen coils, Jentzen, Clarity and Audyn caps and mills rez. I went with fixed Mills instead of the rotary attenuators, I bought a set of res and I can swap in different values of res until I am satisfied. I followed some of the humble homemade hifi page caps ratings without breaking the bank.
Sonically, the new crossover has produced huge plus changes. It's like veil of crud has been vapor blasted from the music, some brittleness in the mid-highs is gone, I am hearing new musical details everywhere and much punchier, precise lows. Overall, I am amazed at the difffs. I don't think I can distinguish a 12 vs a 13.5 rated cap (HumbleHomeMadeHIFI page) but the distinction here are clear. Once the components are finalized I will and button everything down.
Super stoked! 😍
