Where to Buy or Rent

The Blackline X218 is a dual-driver, high performance subwoofer for use with BlacklineX Series full-range loudspeakers. With an operating range of 42Hz-200Hz + 3dB, it produces high output levels with low distortion and can be used singly or stacked horizontally. It features dual 18” (460mm)/4” (100mm) voice coil, long-excursion drivers in a reflex enclosure with eight large ports that reduce air turbulence at high output levels.

Features

  • Dual-driver, direct radiator subwoofer
  • 2 x 18” (460mm) drivers with 4” (100mm) voice coils
  • Durable plywood enclosure
  • Large ports for reduced air noise
  • Powder coated, perforated steel grille
  • Integral ergonomic handles
  • 35mm pole-mount socket
  • Feet for vertical or horizonal operation
  • Rebate recesses for stable horizontal stacking
  • M10 flying inserts

Applications

  • Portable sound reinforcement
  • Live music clubs
  • Bars and restaurants
  • Nightclubs
  • Corporate AV events and conferences
  • Weddings and parties
  • Secondary stages at festivals
  • HoW, leisure centres and retail outlets

The X218 enclosure is constructed from plywood and finished in black textured paint as standard, with white and RAL colour finishes available to special order.

For added versatility in deployment, the X218 is fitted with a 35mm pole-mount socket for mounting BlacklineX full-range enclosures, and integral M10 inserts provide for eyebolt suspension of a single enclosure. Ergonomic handles assist ease of handling and the drivers are protected by a perforated steel grille. Rubber feet on the base of the X218 resist movement and align with recesses in the top surface for stable horizontal stacking. Feet are also provided on one side of the enclosure for vertical operation of a single cabinet.

The X218 is supplied as standard without castors, which are available as an accessory pack.

When used with BlacklineX Series full-range systems, crossover and EQ functions can be performed by the DX0.5 or DX4.0 system controllers or by a Martin Audio amplifier with onboard DSP.
