OVERVIEW

Earth-shaking 18" subwoofer.

PRX418S is an eighteen inch subwoofer which, when combined with the two-way models, provides a sub/sat system capable of generating 135 dB of full-range, high quality audio. They feature a pole mount flange for a full range speaker, recessed handles for easy transport, and most importantly, a rich, thundering sound.

PRX400 passive speakers were designed to provide the sensitivity, frequency response and power handling needed for almost any professional audio environment while still being reasonably priced. Whether you use a powered mixer or an equipment rack full of amps and signal processing, PRX400 passive speakers deliver the sound power and bandwidth necessary to make loud music sound natural and even quiet speech intelligible.

PRX400 passive speakers are made of tour-tested JBL components and feature professional connectivity via Neutrik Speakon combination connectors. PRX400 cabinets are artfully constructed from an 18mm Birch/Poplar multi-laminate hardwood covered in highly resilient DuraFlexTM and feature rugged 16 gauge steel grilles.

FEATURES
High handling capacity
Deep frequency response
Rugged construction
Resistant to scuffs and scratches

Drop a pair of these under your full-range speakers and hear what happens.

    Comments about JBL PRX418S Compact 18" Subwoofer:

    Deep, in your face, Bass from a solid cabinet under 80 lbs.
    SPL is very good from the 1000 Watt Selenium 18" Driver. A pair of these hooked up to a Crown XTI 4000 is a killer.

      Comments about JBL PRX418S Compact 18" Subwoofer:

      Make sure your amp is powerful enough and that you're running a crossover/filter on it so it's only getting sub freqs. Was running Behringer EP4000 in bridge and just couldn't push so I upgraded to an XTI4002 and nearly dropped my jaw. I've since rumbled buildings that were huge and get frequent comments on how great it sounds even though it's not overly large. I've run a lot of systems over the years, and the JBL PRX and STX are just too impressive, even when compared to subs like CV JL36s, which it simply destroys.

          Ordered 2 and one came defective. MF quickly got my replacement out to me before my next sound gig. Its relatively light and not very big compared to previous 18's I have owned. Push it with plenty of power and youll feel it in your chest. Even outside gigs.

            I have 2 of these running off of a Crown XTI2002 bridged each and they shake anything near them.. Also have the matching PRX415m on top. Plenty of spl from this combo.
