RF-82 or Heresy for 2 channel
DCRT08 posted a topic in 2-Channel Home AudioHello. New to the forum. Looked around a bit but didn't see exactly what I was looking for so new post. I'm a music guy and listen mostly to rock. Trying to decide between a pair of used Heresy I/IIs or for about the same money a set of new RF-82s. I'm running a B&K AVR507 receiver. Yes, I know its a HT receiver but at the time I bought it thats what I was doing. I just keep it because these days I can't afford to replace it with something that would be as nice. I just run it in stereo mode. On one hand I might think a 3 way would be better for music, but what do I know? :-) Anyway, any feedback on which speakers might be best for what I would use them for is appreciated.
Khorn Type A / CT-120 / 4500Hz thoughts
codewritinfool posted a topic in Technical/RestorationsEarlier 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.
