Frequently asked questions
Do I need to buy an amplifier for either of these?
The PRX415M is passive and requires an external amplifier to operate. The PRX812W includes a built-in 1500W class-D amplifier, so it is ready to use out of the box with only audio and power cables.
Which has more bass output?
The PRX415M's 15-inch woofer reaches down to 55 Hz and can handle up to 1200W peak power. The PRX812W's 12-inch woofer starts at 52.6 Hz but is powered by a fixed 1500W internal amp, delivering 135 dB peak SPL for tighter, more controlled bass in a smaller footprint.
What is the Wi-Fi feature on the PRX812W used for?
The PRX812W's Wi-Fi and PRX Connect app allow real-time tuning, performance monitoring, and control from any device on set without needing physical access to rear-panel controls during a performance.
Which is better for monitoring on stage?
Both work as monitors, but the PRX415M's 90° × 50° coverage and off-axis smoothness suit wedge or pole-mounted monitor duty, while the PRX812W's self-contained power and app control make it ideal for floor-monitor setups where wireless adjustment during performance is valuable.
