These are the effective, yet affordable, bass traps you've been looking for! They're perfect for smoothing out low-frequency room nodes, allowing you to more accurately hear the full mix without bass build-up or cancellation. Sound passes into our traps where it is slowed it down, decreasing the amplitude of the sound and absorbing the sound. Using Bass Traps as part of your absorptive treatment plan is the answer to creating a faithful critical listening environment in any room, even smaller spaces where waves lower than 80HZ cannot fully develop (a common cause of loud bass). Our high-quality foam bass traps are designed for anyone who is involved with critical listening for enjoyment or professional use.
