The most Innovative Woofer Technology for Home Audio

A wave guide in a simplest form is physical structure for guiding sound waves

A waveguide is a structure that guides waves, such as electromagnetic waves or sound waves, with minimal loss of energy by restricting expansion to one dimension or two.

A domestic home room wall represents a high impedance load to an acoustic wave. A high impedance load (e.g. a room wall) will cause a reflected wave in which the direction of the pressure wave is reversed but the phase of the reflected pressure remains the same.

This reflected energy causes distributed modes which result from out of phase reflected acoustic energy. These modes are a function of the wavelength and the dimensions of the room. The frequency response at the listener coming from a single small acoustic low frequency will not be flat at the listening position because of room modes.

A typical home audio system either uses full range speaker or multiple smaller speakers and a sub woofer to reproduce low frequency sound.

The woofer portion of a large loudspeaker might operate from 30Hz to 500Hz or higher, a sub woofer will typically operate from 20Hz to 100HZ.

The woofers in traditional loudspeakers are small acoustic low frequency sources (realtive to the wavelength) which result in an omnidirectional radiation pattern and sets up multiple room modes.
