I guess I have to sell my Tekton Enzos
More examples of comb filtering - hopefully you now know what to listen for - it is certainly not always a bad sound - quite often it is desirable in pop/rock and electronic music. The faux stereo effect is perhaps the most impressive demo on the link below https://m.youtube.com/watch?v=Zic2eNbxNmY |
shadorne, Now it has been a few yrs that I have owned 3 different sets of panel speakers so I understand completely what you are talking about. I don't play guitar but I do play the piano. Are you referring to upper treble frequency's above 10k. Thank You for this information and you can beat I will be checking this out. Kenny. |
@kdude66 From about 4 to 15 KHz in the case of the tweeter. 4Khz is about 3 inches and 15KHz is about 1 inch in wavelength. As an example imagine two tweeters spaced 6 inches apart. The combined reflected energy they give out will produce total cancellation at roughly 4KHZ, a reinforcement peak at 8Khz and a cancellation at 12Khz etc. The combined sound directly in front and equidistant from both tweeters will be the only signal in the room without these effects (the direct sound) Generally what you hear is roughly 60% direct and 40% reflected if you sit in a farfield position and maybe 75% direct and 25% reflected in a nearfield situation. Here is a plot showing the effect of 1 msec delay - equivalent to about 12 inch spacing of the drivers that produce the same signal. http://digitalsoundandmusic.schwartzsound.com/wp-content/uploads/2014/05/Figure-4.32-Comb-filtering-... Basically comb filtering changes the timbre of the sound (often described as a thinner or hollow sound) as well as creating a wider Soundstage. |
Interesting. When I switched my DAC from old NOS 226 DHT tubes to 101D DHT tubes and changed to a R2R discrete DAC set-up I told one customer that it was a 100% improvement. He did not believe me either so I took one to his home and within the first 30 seconds he said about 40% improvement. When the system (tubes) warmed up for 20 minutes he said yeah it is way better. So don't discount the designers comments. Happy Listening. |
So taking this a step further... Eric told me the Ulfs are far superior in sound to the DI upgrades I have. I have a hard time believing anything could sound that much better after living with the DIs for a while. But I certainly believe Eric and I am upgrading to Ulfs because of it. But until the Ulfs arrive, I am THOROUGHLY enjoying the DIs! |
