Subwoofer Wiring (SVC / DVC)

Dual voice coil assumed (two coils per sub; both coils used).
We’ll total it and suggest mono amp power at your chosen load.

DSP Crossover Frequency Targets

Choose 2-Way (Tweeter + Midbass + Sub) or 3-Way (Tweeter + Midrange + Midbass + Sub).
Optionally add Center and/or Rear Stage. Click “Apply Starter Settings” to prefill values from your reference chart.

Tweeter
Reference start: 4000 Hz (3-way) or 3–4.5 kHz in 2-way.
Use when midrange is present (e.g., ~4–5.5 kHz).
Pro Tips (Tweeter)
  • If harsh, raise HPF or reduce overlap with the next band.
  • Target smooth “S” sounds; avoid splashy cymbals.
Midbass
Pro Tips (Midbass)
  • With sub: ~80 Hz HPF to keep doors clean and punchy.
  • To tame 400–800 Hz “honk,” lower LPF or tighten overlap.
Bass (Subwoofer)
Infrasonic / enclosure protection if needed.
Pro Tips (Sub)
  • Blend near 80 Hz LPF; adjust for localization vs. punch.
  • If it “booms,” raise HPF slightly or verify enclosure tuning.

Test Tracks — Mosconi Sweeps

Downloadable sine sweeps at calibrated levels. What’s this?
1) Sweep — 0 dB

Full-scale sweep for maximum headroom verification. Use carefully.

Download WAV
2) Sweep — −6 dB

Typical safe level for general sweep checks without clipping most chains.

Download WAV
3) Sweep — −12 dB

Great for initial gain staging and EQ shaping without tripping limiters.

Download WAV
4) Sweep — −18 dB

Use when noise floor or sensitive tweeters make louder sweeps risky.

Download WAV
5) Sweep — −24 dB

Fine-tuning crossover slopes, phase, and L/R balance at low SPL.

Download WAV
6) Sweep — −30 dB

Micro-adjustments near noise floor; verifies alignment without stress.

Pro Tip: How & Why to Use Different Sweep Levels

  • Start low (−24/−30 dB) to confirm routing, polarity, and rough EQ without risking tweeters or tripping protect modes.
  • Work up (−18 → −12 → −6 dB) while setting crossover points, phase, and time alignment. Each step reveals issues that only appear as level rises (compressors/limiters, rattles, panel resonances).
  • Reserve 0 dB for final headroom checks only. Watch your DSP and amp meters—if anything clips, back off input sensitivity or master gain.
  • Mosconi workflow: set input sensitivity with the lower sweeps, verify no clip LEDs at −6 dB, then confirm true full-scale margin at 0 dB. Re-check after EQ or crossover changes.
