This review is from: Seismic Audio – Aftershock-18 – Powered PA 18″ Subwoofer Speaker Cabinet (Electronics)
I purchased these a month back from SA website. Don’t be fooled by the low price. These things are built well and perform fantastically. They kick like a mule, hard and fast. Kick Drum pops in these things. Also, listening to prerecorded classical at my studio the other day, and I was amazed at how pristine the low cello notes sound.

I recommend, and will buy again.

Feel the Bass (and still the money in your pocket), August 9, 2013
By 
DJ B Wamm – See all my reviews

This review is from: Seismic Audio – Aftershock-18 – Powered PA 18″ Subwoofer Speaker Cabinet (Electronics)
The Long:

“You get what you pay for” has never been true when dealing with Seismic Audio products. As a start-up mobile DJ I could not afford the big name brands, nor could I even afford their ‘knock off’s. By chance I came across SA and noticed they fit my Pro Audio budget. Doing some research on the Specs of their products one can see that this company means business when it comes down to competing with the higher brands. Just go to their website and see for yourself on the Speaker Comparison tab.
As for these Aftershock 18 inch powered Subs, I’ve bought a pair of these to compliment my 15-SATs and they absolutely rock. Because of their built in amplifier (and me only having a single amplifier for my mains) I was able to power my SA-15Ts through the sub-woofers and add a pair of monitors to my mobile setup and use my amplifier to power those.
These subs are BIG, at 96 pounds one can carry them but their width means you’re going to need a dolly or perhaps a friend to take them longer distances. The grille bends easily to the weight of the cabinet so its a bad idea to use the face of it as leverage to your knee when picking them up. (But the grill comes off easily with a Phillips and its simple to bend it back into its original shape).

The Short:

These Subs pack it all. Built-in amplifier with satellite output to power a main passive speaker. Customize-able equalizer to fit your sound tech’s taste. Rugged cabinet with recessed knobs for protection on the road.
These subs are simply GREAT!

Quality Product at Great Price, November 14, 2012

DJ Bitz – See all my reviews

This review is from: Seismic Audio – Aftershock-18 – Powered PA 18″ Subwoofer Speaker Cabinet (Electronics)
I bought this sub because of it’s features and versatile use. I love the Low Pass Filter and available inputs and outputs (combo 1/4″ & XLR). So far I used it with 2-10″ powered speakers (venues for 200 people) and the bass was more then enough. I’m sure with bigger or additional speakers you can easily play for up to 350+ people. You can use powered and passive speakers with this amp.

You get Two Channel Satellite Power Output
8 Ohm – 2×120 Watts
4 Ohm – 2×200 Watts
Which makes it easy to upgrade your system at will.

It’s not as heavy as it looks but you do need two people because it’s wide. One had on the handle and the other on the back side and your good to go.

I definitely want to buy a second unit and a set of passive speakers for each sub for bigger venues and events.

Hint: When using a powered speaker plug your mixer’s output to a powered speaker and then from powered speaker to the sub.
