Sound Ordnance gear is all about delivering great sound at a great price — and that's exactly what you get with this three-piece amplified PA system. Whether you need a system for your club, school, church, civic organization or fraternity, you'll get clean, crisp sound that can be heard in the back of the room.

Getting out the word — loud and clear
The system features two mounted speakers and a subwoofer. Voices sound clear and distortion-free — even at higher volume levels. Whether you're addressing a town meeting or calling stats at a swim meet, the powerful 400-watt RMS amplifier helps you cut through the background noise.

And music? You can crank it up loud without worrying about the sound breaking up, to keep the crowd moving at that old-school house party. Each top speaker contains a 6-1/2" midrange woofer and horn-loaded tweeter for potent mids and highs, while the sub uses a 12" front-firing woofer to get down low.

Built for the road
The speaker cabinets are made of durable 5/8"-thick MDF and covered with fabric. Metallic grilles protect the drivers themselves, and the speaker terminals are all lockable for secure connections. Built-in handles on the speakers and lockable casters on the subwoofer make load-ins, setups, and tear-downs easier.

Simple, integrated system controls
This PA system's three-channel amplifier is built into the subwoofer. You can control the master volume and the subwoofer volume independently, to dial in just the right amount of bass. The system has one set of stereo RCA inputs and one set of balanced XLR inputs. Connect a receiver or other audio source to play music, or use the XLR input to hook up a mixer or microphone.

Crutchfield Customer Review (What's this?)

A crutchfield rep recommended this to me & I bought "this thing" last year to use while tailgating at football games, and what a crowd pleaser. I actually was approached at our homecoming game by one of the event organizers telling me my music was interfering with theirs.....(Their paid dj....getting drowned out by a local....ha!) Small gigs, parties, events, who needs a dj. Just plug up your ipad, ipod, mp3 player or phone and rock on. Best money I have spent in a while.

Use mine with a nuforce iDO (DAC) and my ipad3 and love it!


Cons: Heavy...LOL
