High SPL LF Speaker
Combined with T10L and T12F, T18W is the low frequency extension part to build a ONAX System.
  • Its dimensions are the same as all ONAX cabinets.
    Therefore T18W woofer can be integrated in each desired ONAX set up.
  • The vented cabinet with a volume of 135 litres houses a heavy duty long hub 18" cone driver with a double centered diaphragm tesler. This feature results in an even SPL at 130dB at the lowest two octaves that reach down to below 40Hz
  • The combination of one T2F and two T18W results in a high performance PA
    system for medium size applications. Each T12F requires only two pieces of T18W for good acoustic coupling effect when setting up a β3 cluster.
  • Extended Excursion / Extended Low Frequency 1600Watt peak extremely long-hub 18” chassis and 135L housing providing 134dB peak for 38-140Hz range
  • Integrated Flying Hardware
    providing the ability of flying 16 boxes on two rigging points without use of any cradle and/or additional chains.
