Recommended efficient associations

Marine Speakers: MTX WET65 or WET77


One pair of WET65 or WET77 plugged into an MTX WET75.2 amplifier is the classic solution. It is possible to bridge two channels to feed a subwoofer (TM1004 or TM1204).


The power of the amplifier should not exceed the power of the speakers. You have to compare RMS powers with RMS powers. Amplifiers should not be exposed to moisture, excessive vibration, or high temperatures.


MTX wants you to enjoy your hearing for a long time. Excessive exposure to loud volumes can damage your hearing. The United States Department of Labor recommends not exceeding the following recommendations:

  • 90db : maximum 8 hours / day
  • 92dB : maximum 6 hours / day
  • 95db : maximum 4 hours / day
  • 97db : maximum 3 hours / day
  • 100db : maximum 2 hours / day
  • 102db : maximum 90 minutes / day
  • 105db : maximum 60 minutes / day
  • 110db : maximum 30 minutes / day
  • 115db : maximum less than 15 minutes / day
  • 120db : immediate danger, 0 minutes / day
