Perlisten D3is + DSP1500A – 3 x 8" Passive In Wall Subwoofer + 1.5kW DSP Amplifier

Perlisten Audio D3is – In-Wall/On-Wall Subwoofer with DSP1500A Amplifier

Dynamic, accurate, fast, minimal, and exceptionally good-looking — the D3is is the little sibling to the D8is, designed for applications where space is at a premium. The D3is works equally well mounted in-wall or on-wall. Proprietary isolation mounts and brackets are designed into the enclosure to reduce overall vibration and noise from transmitting to the adjacent wall. The sub was designed using proprietary nonlinear modeling techniques to simulate and optimize for real-world driver performance — both free air and in-box — with further refinement via Klippel laser measurements. Includes the DSP1500A 1500W external amplifier in its own chassis with a 2.8" LCD touchscreen display. Rack mounting hardware is included. Grills are optional but included.

Highlights & Key Technologies

Driver & Engineering
The D3is utilizes three 215mm (8.5") carbon fiber diaphragm drivers with ±16.9mm linear excursion (per datasheet and spec table; product page overview references 203mm (8") glass fibre cone drivers). The sub was designed using proprietary nonlinear modeling techniques to simulate and optimize for real-world driver performance — both free air and in-box — with further refinement via Klippel laser measurements. Proprietary isolation mounts and brackets are designed into the enclosure to reduce overall vibration and noise from transmitting to the adjacent wall.

DSP1500A Amplifier & Control
The D3is includes the DSP1500A 1500W RMS external amplifier in its own chassis, featuring a 2.8" LCD color touchscreen display. Rack mounting hardware is included for mounting in a standard 19" (403mm) rack — occupying two rack spaces with both front and rear mount options included. No internal fans for quiet operation; ventilation flows front to back with no blank rack space needed between multiple units. The Perlisten Audio app (iOS and Android) via Bluetooth Low Energy (BLE) can simultaneously control up to eight Perlisten subwoofer models. All functions and safeties are controlled by a Ti DSP with 48-bit data paths and a 32-bit ARM Cortex M4 processor with double precision floating point math.

Versatile Mounting
The D3is works equally well mounted in-wall or on-wall. Brackets are included for mounting on a wall or within a structure. The in-wall installation supports adjustable stud spacing of 16–24" O.C. The on-wall installation features a bracket depth of 21-3/16" (538.0mm).
