ATC SCS120iW Pro 15in Active Subwoofer - In-Wall

About: ATC SCS120iW Pro 15in Active Subwoofer - In-Wall

The ATC SCS120iW Pro is a 15” (375mm) active subwoofer optimized for flush in-wall mounting, featuring a shallower cabinet, and recessed rear input connector panel, maximizing floor space. It is the ideal partner to in-wall mounted mid-field and main ATC monitors in stereo, multichannel, and immersive audio applications. The accompanying R1-300 Pro remote-mounted 7U/19” amplifier offers the user the flexibility to install the amplifier in a suitable wall close to the subwoofer, in a control room rack, or in a machine room, with connections made via NL4 speaker and 5-pin XLR cables (sold separately).
