The goal of Echo Busters is to provide a line of acoustical room treatment products which are effective, affordable and visually attractive. An effective line of room treatments is one which provides adequate amounts of absorption and diffusion across the frequency band. To this end, Echo Busters provides four separate products: the aptly named Echo Buster, the Double Buster, the Bass Buster, and the Corner Buster, the latter not included in the review package.

The Echo Buster is intended to provide absorption at mid to high frequencies, an effective absorption from above 4kHz down to about 350Hz. Echo Busters are very lightweight, rectangular wood-frame panels, inset with egg-crate foam and covered with fabric. The panels are available in widths ranging from 12"-24" and heights ranging from 4' to 5' and are intended to be wall-hung with supplied hangers, or are available with optional bases.

The Double Buster serves the dual purpose of both absorption and diffusion. The Double Buster's design is based on that of a bicylindrical diffuser, composed of a center beam down the length of the panel and two bent "wings" of plywood extending rearward from the center beam to the panel's edges. This constitutes a convex surface which diffuses impinging plane waves by reflecting them back into the listening environment in a hemispherical pattern. Externally, the Double Buster is a rectangular, fabric covered panel, similar in appearance to an Echo Buster. Double Busters are available in 4' x 12". The panels can either be wall-hung or left floor-standing with the help of optional wood stands.

The goal of the Bass Buster is to absorb and diffuse low frequency sound waves. The Quarter-round Bass Buster is based on the Helmholtz resonator with a number of proprietary curves to increase effectiveness. Bass Busters are intended to be left standing in the comers of the listening room, where it is known that the build-up of low frequencies occurs.
