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.
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 is not some off brand powered sub. This is a premium product that is built for real professional use. We offer this because we know you will fall in love with this item.

Lets talk power for a second. 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. 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.
