Perlisten D3is – 3 x 8" Passive In Wall Subwoofer

Perlisten Audio D3is – Powered Subwoofer

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. Powered by the 1500W DSP1500A amplifier now in its own chassis, utilizing a 2.8" LCD touchscreen display. Rack mounting hardware is included. All functions and safeties are controlled by a 48-bit data path DSP and 32-bit ARM M4 Cortex processor, able to react in microseconds ensuring sonic accuracy. Grills are optional.

Highlights & Key Technologies

Driver Array & Vibration Isolation
The D3is utilizes three 215mm (8.5") carbon fiber diaphragm drivers (per datasheet and product page spec table; product page overview text references 203mm glass fibre cone drivers), each delivering ±16.9mm linear excursion. 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 is driven by Perlisten's DSP1500A 1500W RMS amplifier in its own chassis, featuring a 2.8" LCD color touchscreen display. Rack mounting hardware is included for mounting in a standard 19" equipment rack. 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. The app (iOS and Android) provides an advanced user interface for customizable turn-on controls, input selection, and multiple PEQ presets. A 10-Band PEQ with 3 user presets is included. Low pass filter is configurable from bypass to 30–160Hz with slopes of 6, 12, 18, or 24dB/oct. Phase is variable from 0–270°. Polarity is switchable between normal and inverted. Configurable auto turn-on and 12V trigger is available via XLR and RCA.

Inputs & Outputs
Inputs consist of one balanced XLR and one unbalanced RCA connection. Outputs consist of one balanced XLR unbuffered, one unbalanced RCA unbuffered, and one Digital AES/2 connection.
