Perlisten D8is + DSP3000A – 8 x 8" Passive Subwoofer + 3kW DSP Amplifier

Perlisten Audio D8is – In-Wall/On-Wall/Freestanding Subwoofer with DSP3000A Amplifier

Dynamic, accurate, fast, slim, beautiful, and massive bass with minimal distortion and zero vibrations. The D8is calls upon all of Perlisten's work over the past decade to create yet another level of fidelity. Push-pull for the ultimate in linearity, dynamics, and power at the lowest levels of distortion — utilizing a unique array of eight 215mm (8.5") carbon fiber drivers accomplishing mechanical force cancelling, with each side acoustically in phase and mechanically out of phase. The force of each driver's motion cancels the force of its opposing complement, resulting in a dramatic reduction of cabinet vibrations at all frequencies. A proprietary, versatile vibration isolation mounting solution supports in-room, in-wall, and on-wall applications, as well as waveforming. Includes the DSP3000A 3kW external amplifier with custom DSP and digital input, housed in a hybrid aluminum/steel chassis with a front-facing 2.8" color touchscreen. Grills are optional. Floor standing base sold separately.

Highlights & Key Technologies

Push-Pull Force-Cancelling Driver Array
The D8is utilizes a unique array of eight 215mm (8.5") carbon fiber diaphragm drivers (per datasheet and spec table; product page detail text references 203mm glass fibre cone drivers) in a push-pull force-cancelling configuration. With each side of the array acoustically in phase and mechanically out of phase, the force of each driver's motion cancels the force of its opposing complement, resulting in a dramatic reduction of cabinet vibrations at all frequencies. Each driver delivers ±18.0mm linear excursion.

DSP3000A Amplifier & Control
The D8is includes the DSP3000A 3000W RMS external amplifier with custom DSP and digital input. Housed in a hybrid aluminum/steel chassis with a front-facing 2.8" LCD color touchscreen, the amplifier can be located on display in-room or hidden in a separate room with other rack-mounted components. It can be placed on an equipment stand or mounted into a standard 19" equipment 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 Vibration Isolation Mounting
The D8is incorporates a proprietary, versatile vibration isolation mounting solution supporting in-room freestanding, on-wall, and in-wall installations, as well as waveforming applications. The steel base is attached to a vibration isolation bracket for freestanding use. On-wall mounting options include outer (4x) brackets spaced 16" O.C. or inner (2x) brackets centered. In-wall installation uses adjustable brackets for 24–29" O.C. studs with eyebolt included; bracket orientation can be up or down. Floor standing base sold separately.
