Once you hear the difference, you’ll never go back. The SubTrap is more than a simple isolation stand. In addition to isolation, it absorbs excess bass and diffuses treble. The end result is a unique product available only from ASC. Raise your subwoofer up to its full performance potential. Now you can finally fill your room with awesome bass power. Just slip the ASC-SubTrap underneath your subwoofer and you’ll create the powerful “SubStack.” Instantly improve sonic detail, changing “fuzzy” playback into a richly detailed picture. Works with virtually any sub-woofer, the ASC-SubTrap lets your subwoofer finally play and be heard to its fullest potential.
