Aperta Sub XL (Single)

IsoAcoustics introduces the Aperta Sub XL subwoofer isolator at HIGH END 2023 in Munich, Germany. The new model expands on the Aperta Sub and makes the patented IsoAcoustics technology available for subwoofers of up to 160 lbs (72.5 kg). Managing the challenging low frequency spectrum, the Aperta Sub XL enables large subwoofers to perform at their best. 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 presents the Aperta Sub XL at HIGH END 2023 from 18th to 21st May in room Atrium 4.2 F210 at the MOC in Munich, Germany.

Aperta Sub XL: for big subwoofers

The Aperta Sub XL brings the patented IsoAcoustics isolation technology to larger subwoofers of up to 160 lbs / 72.5 kg. Taming the power of such mighty speakers is no easy feat, but IsoAcoustics managed to build on the design of the Aperta Sub for smaller subwoofers to perfectly support heavier models. By carefully managing the distribution of low frequencies, the Aperta Sub XL retains the subwoofer’s power while mitigating unwanted side effects, leading to a clearer, more defined sound.



Managing powerful bass: the IsoAcoustics principle

Like its smaller sibling, the IsoAcoustics Aperta Sub XL decouples the subwoofer from the supporting surface. Its specially designed internal isolators absorb the energy that would otherwise be transferred to the structure underneath and cause disturbances of the sound image. It also keeps that energy from reflecting and being conducted back into the subwoofer, where it could cause smearing. The result is a remarkable improvement in terms of clarity and definition – sonic properties that are particularly hard to come by in the low frequency spectrum.



Aperta: design and functionality

The design of the IsoAcoustics Aperta Sub XL is as clever as it is subtle. It discreetly supports and decouples the subwoofer without drawing much attention. Since most subwoofers come with feet in all four corners, the Aperta Sub XL uses the space between the feet to make contact, an important design decision considering the isolators are directional to maintain the speaker’s energy on-axis. It comes with optional carpet disks that anchor the sub into carpeted surfaces if required. The Aperta Sub XL measures at 14.5” wide by 16” deep by 1.5” high (368 mm x 406 mm x 37 mm).
