Frequently asked questions
Can I use the PRX418S alone, or does it need other speakers?
The PRX418S is a subwoofer designed to integrate into sub/satellite systems. It reproduces only 35–250 Hz and cannot cover midrange or high frequencies on its own, so it requires full-range satellites to function as a complete system.
Is the PRX812W suitable as a main speaker for live sound without a subwoofer?
Yes. The PRX812W covers 52.6–20 kHz, making it a complete full-range solution for mid-to-large venue applications. You can use it as a standalone main or monitor speaker, though adding a subwoofer extends bass below 52 Hz if needed.
Which has better portability for touring?
Both are built for touring with durable DuraFlex finishes and all-wood construction. The PRX418S is a subwoofer only and must pair with satellites; the PRX812W is a single all-in-one cabinet, reducing the number of units to transport.
What is the power difference between these two?
The PRX418S has 800W continuous / 1600W program / 3200W peak power handling. The PRX812W has a built-in 1500-watt class-D amplifier. They serve different roles: the PRX418S is a passive subwoofer for extension, while the PRX812W is an active powered full-range speaker.
