I noticed lately that if the sub is connected through speaker level inputs from poweramp, it affects the quality of sound from speakers especially treble(evn though sub is off). Does anyone have an idea why this happens if this can be fixed by any tweak.
Subwoofer placement & crossover do affect the overall tonality. But if there are not much placement options & you need to make the sound more crisp with the sub in your system & if you are using Audyssey XT 32 phone app then you can play around with the " MultEQ Filter frequency range " in the app. Mine is set at 4320 hz but you can increase the range to your taste for Audyssey to apply its filters. The higher you go the sharper it sounds & going lower sounds warmer at least in the Marantz.
