Scheduled for presentation at the High End 2023 show in Munich, Germany, the new IsoAcoustics Aperta Sub XL subwoofer isolator expands on the Aperta Sub and makes the patented IsoAcoustics technology available for subwoofers of up to 160 lbs (72.5 kg). The subtle design does not get in the way of the feet on the subwoofer and remains visually subdued while unleashing the speaker’s full potential. Carpet disks for anchoring the subwoofer into carpeted surfaces are included.

IsoAcoustics has expanded on its Aperta Series with a new Aperta Sub isolation stand designed for subwoofers weighing up to 80 pounds (36.3kg). The Aperta Sub provides a high degree of isolation, allowing the listener to discover greater bass definition from their subwoofer with less complaints from the neighbors. Each set of Aperta Sub includes the isolation stand and four carpet discs with spikes.
