SpeakerCraft SDSi-15 15" Active Subwoofer

The SpeakerCraft SDSi-15 is a powerful 15" active subwoofer built around a high-excursion active driver paired with dual passive radiators, delivering deep, extended bass from a relatively compact cabinet. It suits dedicated home cinema rooms and serious music listening spaces where strong low-frequency output is a priority.

Why we like it

• Triple-driver design combines one active 15" driver with dual passive radiators for deep bass extension
• 1000W peak amplifier power delivers strong, controlled low-end output
• Compact footprint relative to output, thanks to the passive radiator design
• Auto on/off circuitry and RCA input for straightforward integration
• Matt black finish blends discreetly into most room settings

Installation notes

This is a floor-standing 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 your AV receiver or processor's subwoofer output; a USB 5V output is also provided. The unit features auto on/off switching for convenience. Allow adequate clearance around the cabinet given its dimensions of 502mm (H) x 508mm (W) x 483mm (D).
