JBL STX828S Dual 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.

Pros: Great Sound Quality,Good Power Output,Attractive Design
Cons: Heavy / Bulky

I had one and loved the bass output. But now WOW!!! This cabinet just add more chest thumping clothes moving bass. I have one on a crown XTI 4002 and one on a QSC Rmx 4050. I know to complete different AMPS. That is what I have to work with as of now. But when they both start thumping yes sir, you will feel the bass.
