Description

JBL STX818S 18-Inch Bass Reflex Subwoofer

The STX800 Series was designed to bridge the space between light-duty portable PA speakers and flown full-size line array tour sound systems. Our goals at the inception of this project were simple: Offer a high performance, high density system solution in a truck-pack friendly format. Develop concert-worthy floor monitors and side fills that could affordably complement any touring sound system. Deliver an affordable, great sounding subwoofer that could reproduce true low frequency at elevated sound pressure levels. With four full-range systems and two subwoofers, the STX Series can cover just about any professional application. Whether you’re in need of ancillary speakers for a full-blown tour sound system, ground-stacking for a live concert performance, installing speakers in dance clubs or performance venues, touring clubs with your band, or you are a performing mobile DJ, STX800 Series is the smart choice.

will the qsc/5050 be enough to push a pair of these subs?
Dream on Jan 17, 2013
BEST ANSWER: Yes it will
It is possible to compare with the Yorkville LS801, which sounds better and in power they can be compared?
Ernesto on Aug 1, 2012
BEST ANSWER: There is not really a better choice between these 2 subwoofers. Its more of a prefferable choice. First difference is that, they Yorkville is a powered subwoofer pushing 1500 watts with an onboard amplifier and the JBL STX is a passive subwoofer that requires an amplifier. The JBL has a little less wattage as well.
Compare with Yorkville LS801, this STX818S gives the height
Ernesto on Jul 28, 2012
BEST ANSWER: The height of this subwoofer is 22 inches.
Is the JBL STX818S Single 18-Inch Passive Bass Reflex Subwoofer a 4 or 8 ohm speaker?

Awesome Sub!
Pros: Attractive Design,Great Sound Quality

I'm a Mobile DJ and have always used a passive, bi-amped system. I bought one of these, and am powering it with a QSC PLX3402 Powerlight amp in bridged mono mode (2200 watts continuous into 8 Ohms, 3400 watts continuous into 4 Ohms). It's a beast! Serious thump, looks great, and is built like a tank. Even when running hard, it's never bottomed out, and I don't hear any distortion nor power compression. If you know how to run your sound system (proper gain structure, powering it correctly, etc...), you're in for a treat. I liked it so much that I just ordered a second one. Probably didn't need it, but I wanted it!
