Frequently asked questions
Which speaker is better for venues that need standalone bass without a subwoofer?
The PRX425 is designed specifically for this use case, with dual 15" woofers extending to 48 Hz (–10 dB) and capable of full-range coverage. The PRX812W has a single 12" woofer with a 52.6 Hz floor, making it less suitable for deep bass without additional subwoofer support.
Do I need external amplification for either speaker?
The PRX425 is passive and requires an external amplifier rated for 600 W continuous minimum. The PRX812W is powered with a built-in 1500-watt amplifier, so it needs only signal input and a power outlet.
Can either speaker serve as a floor monitor?
The PRX812W is explicitly listed as a dual-purpose main system and floor monitor with multiple input options. The PRX425 is designed as a main speaker; using it as a monitor would depend on your system topology.
What is the key advantage of the PRX812W's Wi-Fi feature?
The PRX Connect app lets you adjust EQ, limiter settings, and monitor thermal status remotely without walking to the back of the speaker during a performance, streamlining live sound operation.
