Subwoofers

Hybrid subwoofers

A combination of several principles, for example a horn with bass reflex or bandpass elements.

How hybrid works
Bass reflex/horn hybrid in cross-section Side section: the driver sits in a baffle and works into a compression chamber. A flaring channel leads from the chamber to the outside. It tunes the chamber like a port and acts like a short horn above the tuning. Compression chamber Volume behind the driver flaring channel Mouth
