    Diffusers must be positioned at correct height in order to perform correctly. Our bases are designed to elevate the diffuser to the correct height to match your usage. Each diffuser height and width dimension will be adjusted to match your room.

    Each diffuser base features our carbon technology to improve your low frequency absorption in either the front or rear of your room. Finishes can be selected to match your diffusers.
