What is a Folded Horn Woofer you ask?
Any horn shape which gradually expands from a small inlet to a large opening will act as a
physical amplifier for sound applied to the smaller end. When coupled to a loudspeaker it
improves its efficiency, but a full-size horn that would work at low frequencies would make
for an impractically large cabinet. By folding the horn back on itself, you can significantly
reduce its size, without compromising the effect. When this technique is is used to take
energy from the back of a speaker and redirect it to the front, you have a folded horn bass
reflex cabinet. Below is an example of a basic folded horn design.
