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.

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.
