The Manchester 1290 by ToneSpeak is a high-powered 12-inch speaker built for guitarists who demand clarity, balance, and control at any gain level. Designed to handle 90 watts with ease, this speaker delivers a dynamic British tone with an even response across the frequency spectrum—no sacrifices, just pure definition.

A robust 50 oz. ferrite magnet provides punch and projection, while the 1.75-inch copper voice coil and fiberglass former ensure durability and smooth articulation. With a high sensitivity of 100 dB SPL, the Manchester 1290 stays clear and responsive, making it an excellent match for pedal-heavy rigs and high-gain amplifiers. Plus, its slow breakup characteristic allows for greater tonal control at all volumes.

Key Features:

  • 12-inch (305 mm), 90-Watt power handling at 8 Ω impedance
  • 100 dB SPL sensitivity for outstanding projection
  • Even, balanced response from lows to highs
  • 1.75-inch copper voice coil with fiberglass former for durability
  • 50 oz. ferrite magnet for bold, controlled sound
  • Slow breakup for enhanced control with pedals and gain

For guitarists seeking power without compromise, the Manchester 1290 delivers the perfect blend of definition, balance, and high-performance tone.
