Dartford 1220

Since the earliest days of electric guitar amplification, alnico magnets have shaped the warm, dynamic tones that define blues, rock, and jazz. The Dartford 1220 continues this tradition, offering players a vintage-inspired sound with modern reliability.

This 12-inch speaker pairs a powerful 34 oz. alnico magnet with a proprietary British paper cone, delivering warm, resonant mids, punchy lows, and a signature chime in the highs. With its naturally responsive and expressive character, the Dartford 1220 enhances the depth and detail of your playing, making it an essential upgrade for musicians seeking tonal perfection.

Key Features:

  • 12-inch (305 mm), 20-Watt power handling at 8 Ω impedance
  • 99 dB SPL sensitivity for rich projection
  • 34 oz. alnico ring magnet for vintage warmth and dynamics
  • 1.75-inch copper voice coil with a paper former for authentic tone
  • Full paper cone with proprietary edge doping for enhanced response

Crafted for those who crave classic tone and expressive articulation, the Dartford 1220 transforms your amplifier into a vehicle for timeless sound.
