Spesifikasjoner for produktene

Control 328C and Control 328CT have been engineered from the ground up to deliver exceptional next-generation performance in a coaxial point source design ceiling loudspeaker. The combination of the low frequency cone and the shaped mounting baffle performs as a true 12 inch (300 mm) diameter waveguide for the high frequencies. A unique metal throat transitions seemlessly to the horn to eliminate high frequency beaming which is common among this category of speaker. The transformer version Control 328CT comes with a pre-attached top quality, low saturation 68 Watt multi-tap transformer for 70V/100V distributed speaker lines.

Features

  • Consistent 120° broadband pattern control covers an extremely large area.
  • Shaped mounting baffle provides the pattern control of a 300 mm (12 in) horn from a 200 mm (8 in) driver.
  • Components
    • 200 mm (8 in) woofer with Kevlarre inforced cone and 50 mm (2 in) voice-coil.
    • 25 mm (1" exit) compression driver.
  • Extraordinary clarity for speech and vocals with extended frequency response for music.
  • 250 Watt power handling with very high sensitivity provides high SPL capability.
  • Advanced high-slope crossover network for constant coverage and smooth, natural midrange.
  • Clean, contemporary grille and optional backbox available.
