The SL700 series is a return to the 21st century style of subwoofers, designed to play music with power and precision!
The SL700 series features an open cast body, a stiff and extremely lightweight cone, a rigid double-layer sub-suspension, EROM suspensions made of high-density material, and a 3-inch voice coil, which allows these basses to hit hard while maintaining great accuracy!
The SL700 series is optimized to reproduce frequencies between 30 - 300Hz, making it an incredibly good subwoofer for listening to music due to its accuracy and power.
The element's open cast body is rigid but it also helps move air through the element = better efficiency!
The SL715 subwoofer does not need a large enclosure to operate. The recommended size of a closed enclosure is a minimum of 25L!!
