Key Specifications

• Drivers: 2 × 10″ LF (dipole), 1 × 1.3″ HF compression driver
• Horizontal Dispersion: 75° constant directivity maintained down to 400 Hz
• Vertical Dispersion (HF): 15° per cabinet; adjustable splay from 0°–14° enables curved array profiles
• Frequency Response (–5 dB):
  • Standard mode: ~60 Hz – 17 kHz
  • CUT mode: ~100 Hz – 17 kHz
• Max SPL (1 m, pink noise, crest‑factor 4):
  • With power amplifiers like D12, D20, D80: up to 139 dB
  • With D6 or 10D: up to ~135 dB
• Power Handling: 400 W RMS / 1,600 W peak (10 ms)
• Nominal Impedance: 8 Ω
• Cabinets per Amplifier Channel: Generally 2 Q1 per channel when used with supported amps

Construction & Rigging

• Enclosure: Marine plywood with impact-resistant paint; metal grille backed with acoustically transparent foam
• Hardware: Side handles; front/rear rigging sockets for locking pins and splay links
• Rigging Versatility: Supports up to 20 cabinets in a flown array, with variable vertical splay

---

Acoustic Modes & DSP Compatibility

• Mode Settings (set via supported amplifiers):
  • CUT mode: Reduces low frequency output when used with subwoofers
  • HFC (High-Frequency Compensation): Compensates for air absorption over long throw distances
  • CPL (Coupling): Applied in longer arrays to balance low-frequency coupling behavior

---

Mechanical Dimensions & Weight

• Dimensions (H × W × D): ~308 × 580 × 410 mm
• Weight: ~22 kg
• Connectors: Dual NL4 (wired in parallel); optional EP5 models for SenseDrive compatibility

Typical Use Cases

• Vertical arrays of 2 to 20 Q1 cabinets for even vertical coverage
• Medium‑ to long‑throw touring systems, festivals, or fixed installations
• Controlled low-frequency alignment using combination with subwoofers and Q‑SUB
• Systems requiring accurate array shaping using amplifiers that support Q1, CUT, HFC, and CPL modes
