Earlier today I modified my Type A Khorn crossovers to support the 4500Hz CT-120 crossover point. I did it in such a way that I could nearly instantly A/B original/4500Hz by using a DPDT switch to introduce an additional 2uF capacitance in parallel with the 2uF tweeter cap and also a 500uH inductor into the squawker path. Note that you CANNOT perform this test while using the stock K77; as others have pointed out, it cannot handle the additional power supplied to it by the increased bandwidth. My listening choices were three very familiar tracks (to me, anyway) Steven Wilson - Hand. Cannot. Erase. - Track 1 : First Regret / 3 Years Older Nidarosdomens jentekor & TrondheimSolistene - MAGNIFICAT - Track 4 : Et misericordia Nidarosdomens jentekor & TrondheimSolistene - MAGNIFICAT - Track 5: Fecit potentiam I can definitely hear a difference in the midrange when I A/B the mods. Quite a lot of the harshness in the midrange is greatly reduced. This is most apparent to me in the female vocals on Track 5 of MAGNIFICAT. I liked it so much that I listened to a few hours of Steely Dan, Ozric Tentacles, Bucky Pizzarelli, and Animals as Leaders... after which I stopped the A/B and made the mods more permanent. For those interested in the diagram, I can provide it as a PM on request.
