The Subwoofer Used in World-Renowned Mastering Studios: Hand-Built ATC C6 Sub Plays with Reference-Setting Control, Linearity, Depth, and Accuracy, Features Full "SL" Spec 15-Inch Driver and 450W Amplifier

There are subwoofers, and then there is the ATC C6 Sub. A professional-level powered subwoofer extensively engineered to seamlessly partner with any pair of ATC loudspeakers — or pairs, in the event of a multichannel system — and deliver monitor-like accuracy, C6 handles the lowest of the lows with reference-grade authority, depth, linearity, control, speed, accuracy, and clarity. There is nothing about this speaker that is not devised to perform to an optimal level, and to look like the proverbial million bucks while doing so. To wit: This strikingly gorgeous sub weighs in at 132 pounds, measures 24.6 x 22.8 x 22.8 inches (HWD), and flexes a mammoth 1000W dynamic output. 

Anchored by a full “SL” spec 15-inch low-frequency driver and critically damped second-order low-pass filters, C6 further flexes with a 450W Class G amplifier and active FET momentary gain reduction overload protection. From a specifications perspective, it throws even more weight around with a maximum continuous SPL of 115dB and an amplitude linearly of 30Hz-300Hz. Numbers, maybe, but evidence that it will spoil you with performance that will only be limited by the caliber of your source, amplification, and cabling. 

Hand-built in England and backed by a six-year manufacturer warranty, C6 gives you total command by way of XLR inputs, 180-degree phase adjustment, variable cut-off frequency, and variable gain controls. The knowledge that numerous mastering studios use C6 to shape film soundtracks, ATC’s five-decade-plus legacy of premier audio design are further, and the option to order C6 in a custom veneer are further reasons this subwoofer proudly stands alone.
