I raised the level by 4.7db on the graph just to get an idea of the frequency on the flat imaginary line.
Level sent to HF was -16db fader AVR level set at -13db DynamicEQ was switched OFF
I muted the LF and started the sweep on the HF tweeter from 900Hz to end at 16,000 KHz since 20 KHz is light-years out of my listening range now, no sense going there if the tone is hard to hear and rarely does it ever crop up in film today. Tones around 10KHz to 16KHz you might hear them on a few odd films a few.
I knew the peak was there having done the sweep before and seeing it on the RTA with pink noise. I can hear tone just fine, I don’t want the tone in my face, I want to smoothness.
I guess it wouldn’t be problem listening to the HF sounds on Alien3 (1992) or Whiteout (2009) where there’s a typing like computer sound effect typing out text on the screen, that’s in and around between 4KHz and 8KHz, DynamicEQ should make the softer sounds still audible, over the room, thou the sound effect on Whiteout is a bit fainter in the mix over Alien3 and The Hunt For Red October (1990) has similar effect, I wonder do computers really sound, like that when we type?
Since the Marantz 1050 are powering the HF tweeters could be the amps adding in hump and slight roll-off still not bad amps for getting on 30 years plus
Also the crossover on the HF tweeter is set at 2.03 KHz on the DCX2496 Link-Riley -24db
