About the Aperta SUB
With a sculpted aluminum frame and patented IsoAcoustics integrated isolators, the Aperta Sub introduces a new standard in acoustic isolation for subwoofers. The Aperta Sub decouples the subwoofers from the supporting surface to prevent the physical transfer of energy that excites the supporting surface, causes room rattle and disturbs your neighbors. The patented IsoAcoustics isolation also prevents the subwoofer vibrations from reflecting on the supporting surface and being conducted back up the subwoofer cabinet. Managing these reflections eliminates muddy bass smear and reveals greater clarity and definition.
Low profile, innovative shape
The Aperta Sub has a low-profile design at 10.5” (265mm) wide x 11.5” (290mm) depth x 1.3” (33mm) height and is designed to be used with front firing and side-firing subwoofers that weigh up to 80 lbs (36.3 kg). Innovative shape allows the Aperta Sub to be positioned directly underneath the subwoofer cabinet without interference with the existing subwoofer feet.
Carpet disks are included with the Aperta Sub for use on carpeted surfaces. The carpet disks provide a strong connection through the carpet to provide a solid foundation for the Aperta Sub.
Built for Bass
More bass, less rattle
We are hard-wired to pick up bass rhythms more than other tones, and low bass frequencies allow the listener to feel a deep syncopated connection to their favorite music or movies.
With a large driver producing low frequencies, the subwoofer creates a large amount of energy that can excite the supporting surface, interfere with other audio components and annoy your neighbors.
The Aperta Sub provides a high degree of isolation and cleans up the muddy low frequency sound, resulting in tighter bass response and greater clarity. The unique patented isolators are directional and are designed to be positioned with the logo facing forward, to resist lateral deflection and oscillations, for greater accuracy and focus.
The Aperta Sub is a must-have for home theater lovers, HiFi enthusiasts, and bass junkies of all ages and is especially beneficial for those who live in apartments or condos.

"The effect the ApertaSub had was night and day, all rattle was gone, and bass became tight and focused. It sounded like an entirely new subwoofer and for $150 for a single Aperta, this was quite the upgrade…”
