Competing in MECA's Sound Quality League is all about sound quality and excellence of installation. It's not about product, personalities, or politics. It's about performance.

  • SQ2 - $55


Winning at MECA Sound Pressure League contests is not solely dependent on how much money is spent and what equipment is run. The classification based on clamped power and cone area puts efficiency ahead of all else, and makes the contest very fair. The clamping equipment doesn't care what amplifier it is measuring, only how much current(amperage) is drawn. This allows everyone a chance, even if they aren't hardcore competitors. So if the question, "Should I compete?" enters your mind, the answer is a resounding YES! because our rules will afford everyone a chance. Our Judges and Members will also be happy to help you learn and grow.

  • Sound Pressure - 15 classes - $30
  • Park & Pound - 5 classes - $30
  • Extra tests (time permitting) - $5
  • MECA Kids - $10 with adult entry
