Professional EQ Curve Design

Understanding Frequency Response

Proper equalization corrects vehicle acoustics and optimizes your system's frequency response. Goldhorn DSP systems offer parametric EQ with precise control over every frequency band.

Target Frequency Response Curve

EQ Band Configuration

Sub-Bass (20-60 Hz)

Controls deep bass extension and impact

Typical Settings: +2 to +4 dB for enhanced impact

Bass (60-200 Hz)

Manages bass warmth and fullness

Typical Settings: Flat to +2 dB depending on cabin gain

Lower Midrange (200-500 Hz)

Critical for vocal clarity and warmth

Typical Settings: -1 to +1 dB for natural balance

Upper Midrange (500-2000 Hz)

Affects vocal presence and instrument clarity

Typical Settings: Flat to -2 dB to avoid harshness

Presence (2-8 kHz)

Controls detail and articulation

Typical Settings: +1 to +3 dB for enhanced detail

Treble (8-20 kHz)

Manages airiness and sparkle

Typical Settings: Flat to +2 dB for enhanced air

Precision Time Alignment

Understanding Time Alignment

Time alignment compensates for different speaker distances from your listening position, creating a centered soundstage with precise imaging. Goldhorn DSP systems provide microsecond-level delay adjustments.

Critical Measurement Points

Driver listening position to each speaker
Passenger position for system balance
Tweeter to woofer distances (components)
Subwoofer to main speaker distances

Time Delay Calculations

Formula: Delay (ms) = Distance Difference (inches) ÷ 13.5

Example: If left speaker is 10" closer than right, apply 0.74ms delay to left channel

Phase Correction Techniques

Driver Integration

Ensures woofers and tweeters work together constructively, not destructively

DSP Setting: 0° or 180° phase adjustment per driver

Subwoofer Phase

Critical for seamless integration with main speakers

DSP Setting: Variable phase control 0-180°

Crossover Phase

Matches phase response at crossover frequencies

DSP Setting: All-pass filters for phase alignment

Advanced Goldhorn DSP Features

Crossover Design

• High-pass, low-pass, band-pass filters
• Butterworth, Linkwitz-Riley slopes
• 6dB to 48dB/octave slopes
• Custom frequency points

Recommended:

24dB/octave Linkwitz-Riley for most applications

Dynamic Control

• Multi-band compression
• Automatic gain control
• Limiter protection
• Noise gating

Pro Tip:

Light compression enhances dynamics without pumping

Signal Processing

• Real-time spectrum analysis
• Pink noise generator
• Signal routing matrix
• Input mixing capabilities

Feature:

Built-in RTA for live tuning feedback

Professional Tuning Workflow

System Configuration

Set up basic DSP parameters and verify all channels are functioning correctly.

Initial Setup Checklist

Configure input sources

Set output channel mapping

Verify signal levels

Test all speaker connections

Crossover Implementation

Configure active crossovers for optimal frequency distribution between drivers.

Recommended Crossover Points:

Subwoofer: 80Hz (24dB/oct)

Woofer to Tweeter: 2.5kHz (24dB/oct)

Midrange: 300Hz - 3kHz (if applicable)

Time Alignment Calibration

Measure distances and apply delays to create perfect soundstage imaging.

Measurement Tools Needed:

• Tape measure (inches)
• Goldhorn DSP software
• Test tones or pink noise
• Quality measurement microphone

EQ Fine-Tuning

Apply corrective equalization to achieve target frequency response.

Tuning Priority Order:

Correct major peaks and dips
Smooth midrange response
Adjust bass extension
Fine-tune treble presence
