Once you hear the difference, you’ll never go back!

The SubTrap is more than a simple isolation stand. In addition to decoupling your subwoofer from your floor, it absorbs vertically expanding bass waves to reduce ringing and mode stimulation. Placement of the woofer away from a room boundary (floor) smooths the frequency response and improves time accuracy.

Installation and integration could not be easier; just slip a SubTrap underneath your sub and you’ll create a powerful “SubStack.” Instantly improve sonic detail, changing “fuzzy” playback into a richly detailed picture by lowering the running noise floor of the room in the all-important low bass range. You'll hear musical bass lines you never knew existed!

The SubTrap Works with virtually any subwoofer. Simply choose the model that is large enough for your speaker to sit on. ASC can also make custom sized units for unique applications. 

"Raise" your subwoofer up to its full performance potential!
