The 7empest

Recommended Posts

Welp, spent some time today building and measuring crossovers.  I think I built six different iterations in total, and took countless measurements of each one.  Here are, I think, the top 3 contenders.  The maroon so far looking best on paper for both FR and phase.  I did spend a bit of time the past day or so listening to the first crossover I was able to build based on the parts that arrived (some of my inductors were on back order and just arrived today).  Made me wonder why the hell I wasted so much time and effort trying to obtain good audio in a car when home audio sounds infinitely better with much less time and money invested, LOL.  I really enjoyed how they sounded with that first crossover, and it didn't measure quite as well as these (well, maybe a little better than the purple xover...but I want to give that design a listen so I kept it in my "top 3").  So long story short there I think I'm ultimately going to be very happy with how these turn out regardless :)

These measurements were done in-room, so ignore 300hz down.  I'm also pretty suspect of the peak in the last octave from 10khz -20khz, but considering my age and past listening habits I'd be lucky if I can even hear most of that octave anyways.  But regardless, all 3 xovers are within +/- 2db from 300hz on up, which is pretty good.  Graph "looks" a little ragged but that's because we're zoomed in pretty close.  If I zoomed out one or two clicks on the graph it'd "look" much more smooth.  Reverse nulls aren't amazing, but I think they're sufficient (maybe a little less so on the purple trace but again, I just really want to listen to that one).  Then I have the individual roll offs.
