Phase-4 Bass Trap

About the Phase-4 Bass Trap

The Echo Busters Phase-4 is a full frequency acoustic treatment tower primarily designed to function as a corner bass trap standing on the floor. It measures approximately 4 feet tall with a 1-foot square footprint (122cm x 30cm x 30cm) and is constructed from 1/4" laminate board with two adjacent sides solid and reflective, and two adjacent sides perforated and absorptive. The top and bottom caps are made of 5/8" medium density fiberboard (MDF). The unit can be rotated to expose either absorptive or reflective sides to the room, allowing flexible acoustic tuning to control 'one-note' bass and also midrange and high frequencies. When placed in room corners, it helps reduce boomy bass and improves imaging and soundstage clarity. The Phase-4 can be ordered in 4, 5, or 6-foot heights. It is covered with acoustic black cloth and is lightweight and easy to position. The design allows for multiple configurations to tailor the acoustic environment, such as absorptive sides facing out for bass control and damped mid/high frequencies, or reflective sides facing out for more lively diffusion and three-dimensionality in the room. It is considered an advanced version of the Bass Busters product, combining absorption and diffusion on four sides for versatile room treatment.
