Frequently Asked Questions
Is this subwoofer active or passive?
The JBL PRX418S is a passive subwoofer, which means it requires an external power amplifier to operate.
Which amplifier is recommended for this subwoofer?
For optimal performance, an amplifier capable of delivering between 800 and 1600 watts at 8 ohms per channel is recommended.
Can I mount a full-range speaker on top of this subwoofer?
Yes, the PRX418S does not include an M20 pole mount socket on its top panel, but its robust, flat design allows speakers to be safely stacked on the floor.
What is the main difference with the self-powered PRX series?
This model (PRX418S) is passive and part of the PRX400 series. It requires external amplification and, optionally, a signal processor. The PRX600, 700, and higher series are self-powered (active), meaning the amplifier and processing are integrated into the speaker itself.
