The EDGE112SP subwoofer features a 12'' woofer with a 3'' Interleaved Sandwich Voice coil. The double ventilated die-cast basket has been designed to grant maximum heat dissipation thereby reducing the power compression level. Mechanical excursion is granted by the DSS (Double Silicon Spider) system, which controls the linearity of the system. The EDGE112SP8 subwoofer is able to handle extremely high powers (400 W AES) both for indoor or outdoor applications. The frequency response reaches 40 Hz with a 125 dB maximum SPL. The cabinet is made of Birch plywood featuring a thick anti-scratch black epoxy paint finish. This model couples perfectly with the EDGE12CXP, EDGE8CXP and EDGE25P satellites. The ideal frequency cut for the EDGE112SP ranges from 125 Hz to 160 Hz.
