Description: 

Add serious low end to your gig with the Rockville Bass Gig RBG-18S powered subwoofer. This is an incredible sounding powered sub that features a 18" driver with up to 2000-watts of peak power for tremendous bass that can run all night without stopping. The subwoofer features a high temperature 4-layer 4” voice coil and is set in a 120oz magnet motor structure. The amplifier features an internal heat sink with a heat sensitive, variable speed, auto turn-on fan cooling system, so even when your music gets HOT – your amp will stay cool. 

You can tailor your sound using the built-in DSP (Digital Signal Processor), which allows you to either add extended boost or extended low frequency enhancement. The DSP circuit also controls over-excursion, thermal, and clipping protection which will ensure you can pound your subs hours straight without any damage occurring. This sub is built to last for years and years of use. A 3 position Low Pass crossover filters out the highs to make your system sound its best whatever venue you're in.

For added convenience and easy set-up, the RBG18S units feature combo XLR – ¼” TRS inputs with Level control and XLR thru puts to secondary units. Just connect your main mix outputs to the subwoofer, and then link your main speakers from the RBG18S! We also have RCA inputs for other devices like home theater systems. This sub features a heavy-duty pole-socket so you can mount your main speaker on top for easy setup and positioning and carry handles so you can easily transport it. Additional controls include a polarity switch, which allows you to invert the subwoofers polarity when installing the subwoofer away from the main speakers. This allows for near perfect time alignment of the subwoofer low-end frequencies to your main speakers.

Lets talk power for a second. Different brands have unique ways of rating their products. So off brands might just make up crazy peak power ratings and write things like 10,000 watts. Premium brands will generally give you legitimate RMS power ratings. So let me explain our ratings and our thought process. This powered sub is 500 watts RMS rated. This is the true continuous power rating. So if a premium brand such as Yamaha or  Mackie were to build this same subwoofer, this is around the same RMS rating they would rate it at. 1,000 watts program power is basically a safe number the sub can handle during peak power of the songs but at an average volume level. This is the way some middle-of-the-road brands would rate it. The peak power of 2,000 watts is what the sub can produce for a split second during the loudest point of a song at full volume. I have seen entry level brands write 4000 watts on subs with less than half the power of this one. Our peak rating is actually a legitimate peak rating, however peak ratings are not important and can vary greatly depending on many factors.
