This Sub Kicks the Standard Up a Notch!

The JBL PRX418S passive subwoofer is based on the same design as its powered brother in JBL's PRX600 Series, bringing you robust bass performance that's ideal for clubs, schools, and houses of worship. The PRX418S is an 18" passive loudspeaker that delivers the kind of performance demanded by rock, pop, hip hop, and many other modern genres, and the extended frequency response is so rock-solid it's almost tangible. If you're looking for a subwoofer with plenty of punch and impact, the JBL PRX418S passive subwoofer is perfect for you.

Designed for powerful performance

JBL's PRX418S passive loudspeaker packs an 18" driver, ready to handle 1,600 watts Program for exceptional low-frequency performance. Even if you're not playing bass-heavy dance tracks, you'll wonder how you ever went without a subwoofer once you hear how the PRX418S adds richness and depth to acoustic music and vocal ensembles too.

Road-ready construction

If you need a high-quality portable subwoofer that can take abuse, you'll appreciate the PRX418S's design. You get 18mm birch/poplar construction, coated with DuraFlex for maximum protection. The hardwood cabinet isn't just strong, it reduces resonance for cleaner sound quality. And with a rugged 16-gauge steel grill protecting the drivers, you can be sure your PRX418S is ready for virtually anything.

Heavily tested for your assurance

When you receive your PRX418S passive loudspeaker, it's already survived JBL's rigorous 100-hour power test. Each component and each system in the PRX400 Series is subjected to 100 straight hours of continuous, high-level input. All JBL Professional products must pass the test before they can grace your venue, ensuring that you're receiving a reliable loudspeaker that can take the real-world rigors that we all put our sound systems through.

  • Passive 18" subwoofer with 1,600-watt Program power rating at 8 ohms
  • Maximum SPL of 130dB
  • Low-frequency range extends down to 35Hz for incredibly rich bass response

Amazing!

I bought 4 of these from Sweetwater two weeks agony and I am completely blown away by them. Maybe the best $3000 I have ever spent on my rig. I was originally going to buy a pair of Peavey SP218 subs because I had heard them recently and was impressed. Sweetwater was out of the SP218 and I needed them THAT DAY because of an unexpected emergency, so I bit the bullet and spent the extra $1000 on the PRX418S. I was a little disappointed because I never imagined that the $1000 would be such a difference. Man am I glad that I was forced into spending that extra $1000! I've used them twice... Once with a quite indoor setting (not a loud rock band) and they had such smooth bottom end that made my mouth water and they gave you punch that you could feel without being loud at all. The second time was at an outside 1000 person gig with a loud 80's rock band and they kicked butt. 4 of them powered by a 3000w QCS RMXa4050 amp was more than enough low end to fill the entire place. HIGHLY RECOMMEND!

Incredible

The punch on these babies is awesome. Clear sound fill the majority of the venues I have performed. I can't wait to get another set. :)

Super Smooth!

We bought 2 of these for our small church sanctuary (e 50' x 50') about 2 years ago… and they rock! We've done everything from acoustic music sets to hosting rap concerts and these subs hold up! We get more compliments on the fullness (yet controlled) sound of our system weekly… and it's all thanks to these bad boys! We're getting ready to break ground for our new building and I'm positive we'll be buying a couple more very soon!

Great Subs!

Just replaced 2 folded horn subs with 2 of these and I am happy with the results. Have lots of punch and can take anything you through at them. Fills a large room with ease. High power rating and low cost ratio hard to beat.
