SpeakerCraft SDSi-8 8" Active Subwoofer

The SpeakerCraft SDSi-8 is a compact triple-driver active subwoofer, combining a single 8" high-excursion active driver with dual 8" passive radiators in a matte black enclosure. Its small footprint and powerful output make it well suited to living rooms and home cinema installations where deep bass is wanted without a large cabinet.

Why we like it

• Triple 8" driver configuration (1 active + 2 passive radiators) for deep, extended bass from a compact chassis
• 400W peak amplifier power for a powerful, room-filling low end
• Low frequency response down to 28-29Hz for genuine extension
• USB 5V output to power an optional wireless receiver, plus auto on/off for convenience
• Matte black finish that blends discreetly into most room settings

Installation notes

This is a standalone active subwoofer rather than an in-ceiling or in-wall model, so there is no cut-out or mounting depth to consider. Connect via RCA input from an AV receiver or processor's subwoofer output; the built-in amplifier drives the active driver directly. The USB 5V output is provided to power an optional wireless audio receiver kit, allowing flexible placement away from the main electronics without running long signal cables. Auto on/off lets the subwoofer power up automatically when it detects a signal.
