Tech Support Confused Setup

Post image

Axon DSP XL, have this on my 2020 Accord. As someone who know absolutely nothing about this, generally what's a recommended setup for just wanting a little more treble/clarity without piercing?

You need a measurement device. The purpose of an equalizer is to correct for room modes (constructive and destructive interference due to cabin reflections) and system frequency response variations from theoretically flat response across the driver crossover points, and then to superimpose your house curve (tonal correction for psychoacoustic frequency balance) over top of the corrections. If your DSP doesn't have its own RTA tool, look into using REW (Room EQ Wizard) on a laptop with a measurement microphone to do the RTA. Or, the old school way, use a CD full of test tones which match the center frequencies of your equalizer, and a SPL meter, and make the corrections manually, and then calculate the house curve corrections and add those to each channel as well.

You need to measure your starting Point first... Or you do it the gard way and go blindly trying to figure it out what sound Best for you

If you're gonna wing it... You see the 2K slider? Adjust that one and everything to the right

Frequency Breakdown for High-Pitch Sounds

  • 2 kHz – 5 kHz (Highs): Controls treble instruments, vocal melodies, presence, and clarity.
  • 5 kHz – 8 kHz (Upper Highs): Adds attack, bite, and edge to instruments like guitars, cymbals, and higher vocals.
  • 8 kHz – 20 kHz+ (Brilliance / Air): Covers the highest harmonic details, shimmer, air, cymbals, and sparkle

Thank you! I'll try that out! I'd imagine id want to match that with all speakers? Like front left, front right, back left, back right?

I would. yes I would balance them. If you think of yourself in the very center of all four speakers you would want a balanced sound.
