DD Audio SL712-D4
The SL700 series is a return to the subwoofers of the 2000s, designed to play music with power and precision!
The SL700 series features an open cast frame, a rigid and extremely lightweight cone, a stiff dual-layer spider, high-density EROM surrounds, and a 3-inch voice coil, allowing these subs to hit hard while maintaining excellent accuracy!
The SL700 series is optimized for frequencies between 30–300 Hz, making it an incredibly good subwoofer for music listening thanks to its precision and power.
The driver's open cast frame is rigid, but it also helps move air around the driver – better efficiency!
The SL712 does not require a large enclosure to perform. The recommended size for a sealed enclosure is as little as 20 L!
