The Blackline X210 is a slimline dual-driver subwoofer designed for situations that call for a visually unobtrusive enclosure. It can be used singly, stacked or flown via integral M10 inserts and its ultra-compact size makes it ideal for applications where space is limited. It features dual 10” (250mm)/2” (50mm) voice coil drivers and generously sized low frequency ports for reduced air noise.



  • Slimline direct-radiator subwoofer
  • 2 x 10” (250mm) drivers with 2” (50mm) voice coils
  • Large ports for reduced air noise
  • Perforated steel grille
  • 4Ω nominal impedance
  • M10 flying inserts



  • 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 X210 enclosure is constructed from plywood and finished in black textured paint as standard, with white and RAL colour finish-es available to special order. An impact-resistant perforated steel grille protects the drivers, and the enclosure has twin ergonomic handles at the rear for easy handling. Rubber feet on the base resist movement and align with recesses in the top surface to assist stacking.


When used with BlacklineX Series full-range systems, crossover and EQ functions can be performed by the DX0.5 system controller or by an iKONamplifier.

    Product Rating

    “By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
