JBL Professional PRX418S Compact 18" Portable Subwoofer System, 35Hz, 2400W Peak Power Handling

When you need big, authoritative bass without sacrificing portability, the JBL Professional PRX418S compact 18" portable subwoofer delivers. Built as a pro subwoofer for touring, DJ, club and house-of-worship applications, the PRX418S provides deep low-end extension down to 35Hz and punchy output thanks to an 18" driver and 2400W peak (1600W RMS) handling. That means fuller mixes, clearer speech reinforcement and room-filling low frequency impact so your FOH mixes and recorded monitoring translate better.

The PRX418S is engineered for demanding environments: a DuraFlex finish, heavy-duty steel grille and vented enclosure reduce distortion and stand up to frequent moves. Its compact footprint and pole-mount capability make it easy to integrate with two-way tops or AV/security control rooms where accurate low-frequency monitoring and reliable playback are required. With up to 135 dB SPL capability, this subwoofer supports applications from live sound to fixed AV installations and surveillance/monitoring suites that need trustworthy bass reproduction. Upgrade your low end—add the PRX418S to your system for fuller sound and smoother monitoring performance.
