Are you using a sub? If not be sure the speakers are set to large, otherwise the receiver isn't sending lows to the speakers. Read the manual as to how to set it up using only L/R speakers.

The only information you'll find on-line is a few youtube videos. They're either White Van or Rent-A-Center. If there was an actual Pro Studio speaker company they'd have a website.

That also can happen. It's why most amps cannot deliver twice the power into a halved impedance load. Those that can typically have very robust power supplies. That, or they understate their actual...
