Ultra-efficient, Earthshaking Folded-Horn Powered Subwoofer

What the hell is a Folded-Horn Subwoofer anyway?
Folded-Horn Reflex Technology Explained:
Any “horn” shape, which gradually expands from a small inlet to a large opening, will act as a physical amplifier for sounds applied to the smaller end. When coupled to a loudspeaker it improves its efficiency. However, a full size horn that would work at low frequencies would make for an impractically large cabinet. By “folding” the horn back on itself (so that the inlet can be near the outlet), you can significantly reduce its size, without compromising the effect. When this technique is used to take the energy from the back of a speaker and redirect it to the front, you have a folded- horn, bass-reflex cabinet.

The Rockville RBG18FA folded horn subwoofer will blow you away. Please do not let the price point of this item fool you. Our goal was to manufacture a crazy loud and great sounding subwoofer. We started by testing subs by other brands that were retailing between the prices of $699 and $1999. One of our favorite subs was an old Mackie model called the SWA1501Z AND SWA1801Z. We loved the folded horn technology. The sub sounded great, packed a huge punch, and sounded as good as subs that cost twice the price. So our engineers decided on creating our sub with folded horn technology as well. When we were done manufacturing this thing, I was so blown away when I heard it. I do not believe there is a sub sounding this loud and this good even at triple our price. This sub should sell for $1199 or more. If you buy this sub and are not happy with this product, we will call tag it and refund you in full. This is not some off brand powered sub. This is a premium product that is built for real professional use. I am so confident in the sub that we are going to offer a 30 day money back guarantee. If you don’t like the power or how it sounds, we will pick it up from your house and refund you. We offer this because we know you will fall in love with this item.

When we first listened to the Rockville RBG18FA and experienced this super-powerful active subwoofer we were blown away. Here's your chance to change the way you listen and play live sound; by adding the RBG18FA Folded-Horn subwoofer to your PA rig. Just be prepared to be amazed! Rockville packed a powerful amplifier into this subwoofer. There is a high quality onboard crossover that lets you get the absolute maximum out of this 18" sub. This unit has lots of connection options including; combo XLR – ¼” TRS inputs with Level control and XLR parallel thru puts to secondary units. Just connect your main mix outputs to the subwoofer, and then link your main speakers from the RBG18FA! This sub features a heavy-duty pole-socket so you can mount your main speaker on top for easy setup and positioning. This item also comes complete with locking 3” caster wheels and carry handles making it easily transportable. Additional controls include a fully adjustable variable low pass crossover circuit and additional XLR High pass outputs.

We built in a circuitry that controls over-excursion, thermal, and clipping protection with individual LED indicators. These features protect the subwoofer to ensure it lasts for years and years.

The 18" driver features a high
temperature 4-layer 4” voice coil and is set in a 130oz magnet motor structure. The subwoofer is enclosed in a high quality solid wood enclosure. This is a heavy duty thick wood. This is a heavy duty enclosure. The sub weighs in at 130 pounds. This thing is the real deal. 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.

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 750 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. 1,500 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 3,000 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 a quarter 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
